10 reasons to choose aLED ALOG100 borosilicate glass lenses

A few years ago we released our own borosilicate glass optics series named aLED ALOG100. This series contains six different glass lenses with angles from 20° to 160°. These glass lenses have so many good features, and in this blog post, you’ll understand why aLED ALOG100 is so popular and why you should really consider them in your next luminaire design.

1. Made of high-quality borosilicate glass

As mentioned already above, aLED ALOG100 glass lenses are made from borosilicate glass. Borosilicate glass is one of the most durable glass materials and it’s known for its light transmittance through the lens compared to plastics and lower-quality glass. Therefore, we can say that borosilicate glass is the best glass material used in glass optics.

2. Always true spectrum

Normal lenses and diffusers tend to shift the color temperature of the LED and also the spectrum and color temperature can change at different angles. Because of the high-quality borosilicate glass, the spectrum stays the same at every angle. In addition, the color temperature stays also same.

3. Withstands ultra-high temperatures

These glass lenses can be used even in extreme conditions. High-quality borosilicate glass makes the aLED ALOG100 glass lenses withstand hot temperatures (up to +450°C). This means that these lenses can be used in hot ambient temperatures or with high-power COB LEDs. This gives a great advantage over regular silicone lenses, as they don’t stand so high temperatures.

4. Easy-to-use holder

Borosilicate glass series

All six aLED ALOG100 lenses share the same aluminum holder. This holder is made from high-quality aluminum and has a black anodized coating. Why this feature is important? It gives the possibility to luminaire manufacturers to easily change between different light beam angles, as the different glass lenses share the same screw holes. The designer can design a luminaire for example with a 120° angle, but there is always the possibility to make the same luminaire from angles between 20° to 160°. Even for a small “limited edition” batch as it is so easy to change.

5. High Compatibility with different COB LEDs

Different sizes of COB LEDs are compatible with ALOG100 glass lenses. You must only remember that the LES size can affect how wide the light beam angle is. You can find the chart below how the angles change with standard Citizen COBs. If you use COBs even with smaller LES sizes, like Citizen high intensity COBs, you can have even more narrow light beam angles.

6. Easy to recycle

aLED borosilicate glass lenses

ALOG100 glass lens contains only three detachable parts: glass lens, aluminum holder, and silicone gasket. This makes the lens easily recyclable as the doesn’t contain mixed materials that are often hard to recycle.

7. Super high efficiency with borosilicate glass

One of the most important feature of optics is efficiency. In other words, how much light can pass through the optic. aLED ALOG100 glass lens series efficiency is up to 93%. In conclusion, only 7% of the light is lost to the optics.

8. Comfortable antiglare finish

Four of six aLED ALOG100 models have an antiglare finish. Antiglare finish reduces the annoying glare that comes from the luminaire. Luminaires with antiglare optics give a more comfortable working environment. For instance, in warehouses or factory lines, as they don’t irritate the eyes.

9. Flexible product for multiple applications (500lm – 40 000lm)

The first application for aLED ALOG100 glass lenses that comes to mind is of course industrial use, but there are endless possibilities for the series. You can achieve from very narrow light beams to wide light beams that cover large areas. In addition, they can be used with many different lumen packages for example from 500lm to 40 000lm.

10. Long lifetime, no yellowness

One ultimate feature of glass material, in general, is how it will always hold pure color. For instance, some silicone materials will turn yellow in time. The yellowness of course affects the color temperature of the luminaire, so the color temperature can change warmer in time.

Here are only 10 reasons, but I could make plenty more. You can also download a brochure from the link below. From the brochure, you’ll find more precise information about the products and also mechanical drawings. If you have any questions about these glass lenses, you can always email us at info@light.fi

Tero Explains: What is EPREL for light sources? 2/3

The first article of this 3-part blog post series was dealing with the near-term history of European directives and regulations related to energy efficiency and different energy-related products (ErP), not only energy-using products (EuP).

Starting from Kioto 2005, this process has then proceeded to the situation, where new kinds of regulations have been taken into use, concerning many energy-related products, the latest of those being light sources.

Since 1st September 2021, the insertion of light sources into the EPREL (European Product Registry for Energy Labelling) database has been possible officially. Some problems have occurred in the technical insertion process and also in decisions over which component is a light source and which component is not. The term ’light source’ is defined in the European Commission Regulation EU 2019/2020 laying down ecodesign requirements for light sources and separate control gears (Single Lighting Regulation, SLR).

In this blog post, you can learn how light sources are categorized and what this categorization means in each case.

Categorizing the light sources – is the light source removable or not?

I shortly presented the terms of ’containing product’, ’light source’, and ’separate control gear’ in my earlier blog post in this series. SLR requires that the light source and separate control gear are removable so that the luminaire/fixture can be called the containing product. If not removable, the whole fixture itself has to be regarded as a light source.

Here starts the categorization. I concentrate on light sources in this post. The easiest case is a containing product without a light source: Not Applicable (it is just an empty luminaire body that has no light source included). The second easiest case is the LED lamp that you can buy from a retail store. Then it is not containing a product but only a light source. The sales package in store should include an energy label and other information defined in SLR regulation. Additionally, the lamp information should be added to the EPREL database.

Then let’s proceed into the case(s) where containing product includes the light source.

The first question is that is the light source itself removable? If it is, then it has to fulfill light source requirements defined in Ecodesign/SLR regulation. It is enough that the light source is removable from the containing product without breaking the light source. The containing product is allowed to still deteriorate in that case, but not the light source.

Then there is the next case. If the light source is NOT removable without breaking it, then the whole lighting fixture is considered a light source. The sales package of the containing product has to include an energy label and also other information defined in SLR regulation.

So, the key point is the question, is the light source removable or not? The question, is the light source replaceable or not, is not relevant otherwise than for the end-user that is you or me, a consumer. The supplier (or manufacturer) has to inform in their technical representation, why the light source is not replaceable. This technical documentation should also include information that “this containing product includes a light source the energy efficiency class of which is X”. X can vary from A to G in the new energy efficiency classification. Light source information together with the energy efficiency class must be found in the EPREL database.

Requirements defined in SLR/Ecodesign Regulation

There are several requirements defined in SLR/Ecodesign regulation. These are:

  1. Energy efficiency requirements
  2. Functional requirements
  3. Information requirements (markings)

Energy efficiency requirements

First of all, energy efficiency requirements demand that power consumption of a light source can’t exceed Pon,max (W), which is defined for different light sources in the 2019/2020 SLR regulation. Pon,max depends on many parameters, some of them are real and measurable values and part of them are computational values or factors/multipliers. Computational values are based somewhat ”loosely” on the real world.

If you measure for example your LED board/module in the integrating sphere, and the light source is defined as a non-directional light source (NDLS), you can use all lumens that you measure in your sphere as useful luminous flux (term defined in SLR regulation). If you have a directional light source (DLS), the regulation defines which portion of light you can use for this directional light source. Usually, the measurement for the DLS light sources is better to carry out with a goniometer that can measure light intensity at different angles unlike with integrating sphere which collects all the light rays and integrates them for the spectrometer through an optical fiber.

This relates essentially to EPREL energy class information because you define the energy class according to the following equation:

hTM = (Fuse/Pon) x FTM

where hTM is total mains efficacy, Fuse and Pon are LED parameters (useful luminous flux and power consumption of the measured LED board, COB LED, or any other light source) that are measured from the light source and FTM is a multiplier that is 1.00 for mains light source (MLS, e.g. AC LED) and 0.926 for the non-mains light source (NMLS, e.g. LED board that needs a separate control gear for operation).

The updated measurement software can calculate hTM value directly when you first choose in the software, is your light source NDLS or DLS, and is it NMLS or MLS light source. So spectrometer first measures luminous flux and power consumption and calculates LED luminous efficacy, and then by using a correct multiplier for your light source, calculates total mains efficacy that defines the energy class. For example, in the case of an LED board with separate control gear, this multiplier is 0.926 (see the previous paragraph). Then you can add your LED light source to the EPREL database by filling in all public information, and the EPREL database creates the final energy label for your light source. For market surveillance, you have to add also other technical information, that is not publicly available for everyone.

Functional requirements

Then there are functional requirements. They include many parameters that also depend on the used control gear (LED driver in our case).

  • CRI index ≥80 (outdoor and industrial applications are the exceptions)
  • Power factor cosf (certain limits, depending on the control gear used)
  • Lumen maintenance factor (LED and OLED light sources) àbased on L70B50 value in hours
  • Survival factor (LED and OLED light sources) àrelated to the lumen maintenance factor
  • Color consistency (LED and OLED) àhas to be MacAdam 6-step or lower
  • Flicker PstLM (LED and OLED), depends on the control gear à PstLM≤1.0
  • Stroboscopic effect (LED and OLED), depending on the control gear à SVM value≤0.4

Two last values are defined at full load condition.

Information requirements (markings)

Finally, there are information (marking) requirements.

The surface of the light source itself (not package marking):

  • Useful luminous flux (lm)
  • CCT/Correlated color temperature (K)
  • For directional light sources (DLS), also radiation angle (°)
  • Depending on the size of the light source, the priority is 1) Luminous flux, 2) CCT and 3) radiation angle.

Packing information:

For all light sources, which are sold separately in an independent packaging (but not in a containing product) through a point-of-sale, there are several requirements regarding the packing information. Some of these are mentioned below. It is to be noted that the three first ones shall also be marked on the surface of the light source, given that there is space for all three.

  • Useful luminous flux (lm)
  • CCT/Correlated color temperature (K)
  • For directional light sources (DLS), radiation angle (°)
  • Electrical interface details
  • L70B50 lifetime (hours)
  • On-mode power (Pon)
  • Standby power (Psb)
  • Networked standby power (Pnet)
  • CRI/Colour rendering index
  • Indication if CRI<80 (note; the application must allow it)
  • Indication if the light source is designed for non-standard conditions
  • Warning sign, if dimming is not allowed or can be realized only with specific dimmers
  • Warning sign, if the light source contains mercury

As an alternative to text, the information can also be given in the form of graphs, drawings, or symbols. Besides this information, the packing must show the energy label.

If a light source is being sold as a part of containing the product (and the light source is removable), the requirements are different. In this case, there can’t be any energy label on the containing product packaging. The packaging must indicate the following:

  • Information on whether the light source is replaceable or not, must be shown on the packaging (in the case of end-user sales) or on a free-access website
  • Information if the light source can be replaced only by a professional

As an alternative to text, the information can also be given in the form of graphs, drawings, or symbols.

Conclusion

This is what SLR is in a nutshell. And how you define energy class for your light sources. For printing the label from the EPREL database, you can ask help from the EPREL help desk or your local officials.

In the third, and the last, article of this blog post series, we concentrate on the effects that these regulations may set for the whole lighting industry. As you can see, many parameters depend also on the driver/control gear that is used with the light source. How this affects the component (light source and/or control gear) selections to make genuinely Eco-designed containing products, this we will discuss in the last part of this series.

Meet our new Category Leader

At the beginning of September, Oskari Viitaniemi started in our lighting component sales team as a category leader for power supplies. He will bring a lot of knowledge of sales and logistics to the team with his great experience in the field. His time will mainly go into sales, but he will be also part of the product development team.

We want to introduce Oskari to you better, so we will be asking him a few questions.

What is your role and what does it entail?

I am a category leader. My responsibilities will sharpen in the following months, but I’m part of the sales team and I will get one product category to lead. The last month I have been working a lot with LED drivers and with aLED AURA+ series, so maybe that will give a little bit of clue.

What drew you to the company?

The LED industry has always fascinated me. There are so many new things to learn about LED lighting which intrigued me. Also, I believe lighting is very important in our lives and a good chance to save energy.

How do you feel so far after 3 weeks of working here?

I am very excited, but to be honest, last month has been tough as I started in a new company, a new role, and a new field. There is a lot to learn. Although, it will take a while for me to learn everything I need to know as it is not possible to learn everything all at once.

You have received a lot of training these past few weeks, what is the most interesting thing you have learned so far?

I think the most interesting thing I have learned is colour rendering Index because I had never heard of it before coming here. It is interesting how much a small change in the value affects the light quality.

What are some of the new things you have learned and is there anything that has affected the way you might think or changed your view on things?

Previously, I thought any LED light you buy from the store is the best you can get but now I know what to look out for when buying them and that has changed the way I shop for light-related products, and also my view of the lighting industry. It is more complex than I initially thought.

What do you find most interesting in the lighting industry?

The almost complex amount of possibilities to light up the world. Like different features in drivers will give you different results in the controlling light.

What do you like to do in your free time? Any fun facts?

I like to play disc golf, ride my bike in the woods and play sports. Friends are very important to me, so I like to hang out with them and do sports with them.

Do you have a favourite product yet?

Yes, I have already fallen in love with the aLED AURA+ drivers. I think they are great and quality drivers for different kinds of lighting applications. If I had to choose a driver, I would probably choose a DIP switch driver, because of its flexibility.

What do you find most challenging so far?

Not most challenging but most time-consuming is to understand the lighting industry language and also to find the right solutions for a customer.

Is there anything you would like to say to our customers?

So far, I have noticed that we have great knowledge and an amazing team spirit in the office so our customers shouldn’t hesitate to ask us for help.

Now we are almost at the end of the year. What do you especially expect from the year 2022?

I am not very sure yet. I want to get deeper into the industry this autumn. As I gain more knowledge, then I think I will know what to expect.

If you have any questions, please contact Oskari Viitaniemi by email oskari.viitaniemi@light.fi

Tero Explains: The New EU Regulations coming on September 1/3

In this blog post series of 3 articles, our technical sales Tero Nurmi will tell you about the new EU regulations which will take part on 1st September 2021. In this blog series first Tero will tell you, what are these two different regulations: Single Lighting Regulation (SLR) and Energy Label Regulation (ELR). After that, Tero will go deeper into the subject of how this really affects the lighting industry.

What is ErP? 

ErP is the abbreviation of Energy-related Products. It also refers to Energy-related Products Directive (ErP) 2009/125/EC that replaced the old Energy-using Products Directive (EuP) in November 2009. The original EuP was taken into use in 2005 to fulfill the Kioto agreement requirements for reducing carbon dioxide emissions.

The ErP broadened the range of products that were covered in EuP. Earlier only directly energy-consuming (or using) products were covered. Now ErP directive also covers the products related to energy. This could be for example water-saving taps, etc.

The idea is to cover the whole product supply chain: design stage, production, transport, packaging, storage, etc.

Products that comply with this new ErP directive are recognized from CE -marking. In this case, the CE -mark covers product safety and energy efficiency requirements. 

How this relates to lighting? 

If we take the new directive, ErP EU 2019/2020, we can divide it into two groups concerning ecological design requirements:

  • Light Sources 
  • Separate Control Gears 

These requirements can also be applied to luminaires. The luminaires are so-called containing products that contain a light source(s) and control gear within the luminaire.

The development has gone further: now these ”ecodesign” principles are applied to the smallest possible units that can be considered as light sources. In this text, we do not go too much into details. I’ll explain everything more precisely in the further blog posts.

In December 2019, the European Commission published two different regulations: Single Lighting Regulation (SLR) and Energy Label Regulation (ELR). The former is also called Ecodesign Regulation for Lighting. SLR defines performance requirements, which are product-specific, for energy-using and energy-related products, while ELR includes labeling requirements for selling the products in the EU market.

There is a general state of mind that both these regulations, SLR and ELR, will apply from 1st September 2021.

SLR and ELR, and especially their application to LED light sources, will be handled more elaborately in forthcoming posts. 

The New Citizen Generation 8.5: Maximize the LES lumen output

Two weeks ago we launched the new product, aLED SUVISPOT, which is all about the greatest color rendering there is. However, sometimes the application doesn’t need great color rendering. We are now talking about industrial lighting and some outdoor lighting like in the sports fields. In these cases, the lumen output is more important than color rendering.

In this blog post, I’ll tell you about a new product from Citizen which is the answer to all high lumen output needs. It’s Citizen generation 8.5.

Citizen generation 8.5 has two main features. First, you can drive it with 300mA per diode, which is 120mA higher than in basic generation 8. Second, it has higher efficacy than in generation 6. These two features combined give you the opportunity to maximize the lumen output of the LES. Let’s get more into that.

Features of the new 8.5 Generation COB LEDs

  • Ra70min 
  • MacAdam 3step
  • 5% better lumen efficacy than in generation 6
  • Higher maximum driving current – 300mA
  • Available in all regular Citizen COB sizes
  • Up to 82 000 lumens
  • Great compatibility with aLED ALOG100 glass lenses
    • Angles from 20° to 160° and street light lens 140°x70°

Maximizing the lumen output of the LES

All Citizen COB LEDs has four different LES sizes. Because the LES size affects how optics work, LES sizes are often one of the principals of the technical luminaire design. Here we will give you some examples of how Citizen generation 8.5 LEDs can be used. In addition, we will tell you the maximum lumen output of each LES size. Because our aLED ALOG100 glass lens series goes so well with these LEDs we will use them too in the examples.

What is LES? – LES comes from the words Light-emitting surface.
In the nutshell, it means the size of the light area.

Maximum lumen output examples

The next examples are all generated with a simulator. Note that, actual values may differ by the application. All examples use the same aLED ALOG100 borosilicate glass lens (ALOG100-045). In the lux values, the optic’s efficiency has been noted.

Ø9,7mm – 5 758 lumens

This first example is something that I think is really interesting. Here is the smallest COB LED which LES diameter is only 9,7mm. From this tiny LED you can get almost 6000 lumens. This is 1300 lumens more than with generation 6 equivalent products. 

In other words, with this LED you can make luminaires with high lumen output and a very narrow beam angle.

Ø14,5mm – 14 429 lumens

As I said before LES size affects the light distribution. Here we use the same ALOG100-045 glass lens as in the previous example. However, the LES size is now 14,5mm, so the light beam angle expands to 30 degrees. This means that even though we have now three times more lumens, the lux values stay almost the same. But note that the diameter of the light beam (@14 meters) is now 1,5 times bigger.

Also, with this LED you can get over 3000 lumens more than with generation 6 equivalent product.

Ø22,0mm – 38 370 lumens

In this example we are getting 38 370 lumens from LES size 22mm. This is over 8000 lumens more than with generation 6 equivalent product.

This solution gives you tremendous amount of light to very wide area.

Ø32,8mm – 77 204 lumens

This last example is something extreme. Here we are getting the highest lumen output on this series. With the biggest COB LED (LES Ø32,8mm) you can get 77 2004 lumens with 612W. Which is over 16 000 lumens more than with generation 6 equivalent product.

Where to use Citizen Generation 8.5 COB LEDs?

Now that we have gone through some examples, and maybe you have already invented a couple of uses for the LED yourself, I will tell you application ideas for the new generation LEDs.

As this series’ color rendering index is only Ra70, it is not meant for places where you want to make the colors pop. That is because generation 8.5 COB LEDs are great for industrial use, where you need a lot of light and the height of luminaire can be really high. Warehouses, airports, and sawmills are great places to use these LEDs.

Also, when you need a lot of light and a narrow light beam angle, you should note this generation. 20° light beam and 5700 lumens is a really tough duo.

A New aLED KIDEFLEX LED Strip – Save energy up to 84%

We talk a lot about energy saving in general lighting, but somehow we have forgotten that in LED strips. In this blog post, I will present a new aLED product: The aLED KIDEFLEX LED strip. It’s a new kind of LED product that can save energy up to 84%.

Energy-saving in the LED Strips

In the regular lighting market, it is always very important to think about the energy efficiency of the lighting fixture. However, in the age of LED stripes, I think we have forgotten that. Just a couple of years ago we all wanted to change the light bulbs to LED bulbs because of the energy saving. Now we are decorating residential and commercial buildings with hundreds of meters of LED strip. That isn’t always the most ecological option as their regular wattage per meter is 10W and they can go up to 50W/m.

Often, we are making lighting designs that produce too much light. This way we are making lighting pollution as we use more light that we need. For instance, porch or balcony lighting doesn’t need 1000lm/m. 250lm/m is enough for a beautiful and energy-saving solution of decoration.

A New Life Changing LED Product

Reel of aLED KIDEFLEX LED strip
CAF1000-160-930-001

At Arrant-Light Oy green thinking is very important to us. This is why we wanted to design modern LED strip with super high efficiency and differ the ones in the market. Now we are coming out with the first professional high efficiency CRI90 LED strip.

aLED KIDEFLEX LED strip is a new type of LED strip. Here are some of the great features of the strip:

  • Super high efficiency – efficacy is >145lm/W @3000K
  • Ultra even light – up to 160 LEDs/m
  • The best color quality – color rendering index CRI >90
  • Consistent quality – MacAdam 3-step
  • Super durable attachment – uses high-quality 3M tape
  • Lower wattage solution – better heat management equals to longer lifetime

aLED KIDEFLEX LED strip’s efficacy is >145lm/W @3000K. Regular LED strips’ efficiency is approximately 75lm/W. That means that our LED strip can produce the same amount of light with two times less power. Saved power equals saving energy and money. Let’s get more into that.

aLED KIDEFLEX LED strip is now available in:
  • 250lm/m – 1.6W/m
  • 500lm/m – 3.5W/m
  • 750lm/m – 5.25W/m
  • 1000lm/m – 7.0W/m
  • Color temperatures from 2700K to 6500K
  • 24Vdc
  • width 8mm

Do you need lumens or watts in lighting?

That is one basic question what we need to think. Many LED strips are marketed only with the power per meter. There are LED strips from 3W to 44W per meter and you should try to pick from them the best for your application.

What you really need is lumens. You need to think about how much light do you need in your application. For instance, decorative, indirect and general lighting needs a whole different amount of light. Many lighting guides stick to how much power do you need in certain places. The power of the LED strip tells really nothing about how much light you are getting as it’s all depending on the efficacy.

Let me give you some examples.

Example 1: Save energy in decorative lighting

Calculation about saving energy in lighting

In the picture above we are comparing two LED strips: a regular LED strip and the new aLED KIDEFLEX LED strip.

For decorative lighting, 250lm/m is enough. That gives you a beautiful atmosphere that you are looking for decorative purposes. However, the common thought is that 10W/m is the power you need. That’s way too much and you are wasting energy.

As you can see, our LED strip has high efficiency, so we can produce 250lm with only 1,6W. This means that you can save 42W energy in only 5 meters.

Example 2: Save energy in indirect lighting

calculation about using same amount of light but saving energy

In the picture above, we are again comparing our aLED KIDEFLEX LED strip to a regular CRI 80 LED strip. In this example, LED strip is going to be used in indirect lighting. This means that we will need more lumens. Therefore, 750lm/m is the right amount of light.

As our LED strip has very high efficiency, two times more compared to regular ones, we can produce the same amount of light almost with half power. In other words, you can save only in 5 meters 23,75W power.

Example 3: Save energy in new residential buildings

In previous examples, we only talked about 5 meters. Now let’s compare LED strips in the bigger picture.

In the picture above, you can see a calculation of energy-saving in a brand new home. Right now we are building new modern homes that can use 500 meters of LED strip to decorative lighting. This means that, If you change the regular 10W/m LED strips to our energy-saving option you can save 4200W/h. This is a lot more ecological choice. In addition, saved energy equals to saved money. This means that you can save over 1000 euros annually in electricity bills in the European electricity price level.

In conclusion, small change can make big difference.

How do you know how much light do you need?

Let’s go through some examples about how much light do you need in certain places.

Decorative lighting – 250lm/m

lighting in handrail

250lm/m is great for decorative use, such as floor moldings, handrail, stairs and balcony railing. 250lm/m gives you atmospheric lighting without wasting too much energy and it doesn’t make the decorative light too bright.

More illuminating decorative lighting – 500lm/m

indirect lighting in hall way

500lm/m can be used almost in the same applications as the 250lm/m, but when you want a little bit more light or you can use it as indirect lighting if the need for light isn’t high.

Indirect lighting – 750lm/m

indirect lighting in bathroom

750lm/m is great for indirect lighting. For instance, in bathrooms (Note! aLED KIDEFLEX LED strip needs profile when used in bathrooms. We have over 100 different LED profiles in our product range.)

General lighting – 1000lm/m

LED strip in the kitchen

1000lm/m is great when needed a lot of light. For instance, in the kitchen below the cabinets, or in the offices. 1000lm/m gives you a lot of light and helps you work with detailed work tasks.

In conclusion, you need to think about how much light do you really need. And remember, in the examples above we are only talking about 5 meters. It’s really a short distance in LED strips. The reality is that homes and industries are using dozens or hundreds of meters of LED strip in their applications. This means a huge energy-saving option when changing to a high energy-efficient LED strip.

Arrant-Light Oy Wishes Merry Christmas and Happy New Year!

Dear Customers and Partners,

It is the time of the year again where we can wind down and enjoy this year’s achievements with family and friends. All our customers and partners are part of the Arrant-Light family. Without you all, we would not exist.

There were lot of happenings in 2019, but to Arrant-Light Oy the highlight was our company celebrating its 35th Anniversary in November. I clearly remember, when my father Tarmo started contemplating about founding his own company and ended he up taking that brave leap. He always had the drive to develop and bring the most efficient, advanced and long-lasting products to the markets and the customers. By founding his own company, he was able to carry out his own visions and ideas and further them on his own terms.

We continue to strive to uphold the teachings and traditions he has given us. This is one of the reasons why we have been able to maintain the relationship with some of the customers and partners from the very beginning. This reflects well, how to us, the customers, their needs and satisfaction has always been a priority in everything we do.

We have channeled our Christmas gift funds to charity this year again. Through the SaveThe Children -foundation, we are supporting the youth education and through the Scout District we are donating the opportunity to attend the Otava 2020 camp in Turku Archipelago next summer to a few children from less fortunate families.

Once more, I would like to thank all our customers and partners for a successful year and on behalf of myself and the company to wish Happy holidays and success for the coming year 2020.

Best wishes,
ARRANT-LIGHT OY

5 ways to reduce packaging waste and make them more user-friendly

Recycling of the carton boxes

To us, it’s very important how the components that we import have been packed. Our aim is to minimize the excess packaging waste, to avoid plastic and to design a packaging that is user-friendly, easy and effortless to handle. The same goes with our components as well. In this blog post, I will be explaining 5 ways, how we minimize the amount of waste in our packaging and make them easier to use.

1. No excess plastic

It’s easy to use bubble wrap to protect the products for shipping. How ever, we prefer to favor alternative methods, so the packaging will produce the least amount of waste. For the past few years, we have brainstormed with our suppliers on how to minimize the amount of plastic in packaging. For example, from now on, our products will not be packed in individual plastic bags.

2. The packaging materials must be easy to recycle

Sometimes cardboard packages have been stapled with metal staples, which makes recycling more difficult. We opt to use plastic- or paper tape to secure them instead.

3. No wasted space in packages

Transporting air across the globe is very un-ecological and expensive. That is why we want our packages to contain the products, and not packaging waste and air. This is an efficient way to reduce shipping costs. We also ask our suppliers to pack the drivers directly into boxes, without individual packaging.

4. No excessive waste

The use of strain relieves in drivers divides the opinions and to some luminaire manufacturers, they are just waste. Therefore, it is possible to choose to order the majority of our drivers with or without the strain relieves. This is another way to reduce the amount of waste.

5. Stickers – the solution for easier storage

As well as the packaging materials, we have made our products more user-friendly with stickers. For example, our aLED-cooling element cartons have stickers on the side with a picture of the product and the key information. These make storing easier when the products are easily found.

Arrant-Light Oy is the new official distributor of the Lifud-drivers in Scandinavia and Russia. The Lifud drivers we import has customized packaging without excessive plastic. The original plastic trays have been replaced with cardboard option, and the drivers are not individually packaged. This way the luminaire manufacturer doesn’t need to worry about the high quantity of waste from the packaging materials of the components, therefore speeding up the production process.

aLED Modules – high efficacy and quality

aLED LED nodules

aLED products are Arrant Light Oy’s own line of LED modules. 

We have been designing and producing LED modules since 2008. Our LED modules have been used for mass production luminaires and also for projects that need a special solution like in hospitals, automotive industry, safety light, and architectural lighting. We have dozens of standard LED modules at stock for instant deliveries. Also, we can quickly design and produce customized LED modules and prototypes for your needs.

We always use the best components for our LED modules, for example highly thermally conductive aluminum PCB and high reflective PCB solder mask. These features will make the LED modules and final product more efficient. We have chosen all components precisely and they fulfill our high-quality standards. 

We can produce LED modules exactly for your requirements.

  • Color rendering index (Ra80, Ra90, and Ra95)
  • Different color temperatures (1850K, 2200K, 2500K, 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, 6500K and also special colors)
  • Tunable White and Dim-to-Warm
  • RGB and RGB-A
  • Different shapes of the module
  • Constant current and voltage

We Always Test our LED Modules

our integrated sphere

With our integrated sphere, we can measure LED modules and luminaires up to two meters in length. This way we can always get precise information about light quality and electrical features. In the production line, all our LED modules are already measured, but we still measure some modules of every production batch with integrated sphere. We want to be sure that current, voltage, lumens, efficacy, spectrum and color rendering index are what we promise. This way we can check that our products are uniform, high-quality and with the specs agreed.  

If you use our aLED modules, we can offer an additional measurement service for your luminaire’s photometric values.

Season’s Greetings From Arrant-Light Oy

Dear Customers and Partners,

It has come again the time of the year when all jobs have been done and it is time to spend a peaceful and relaxing Christmas holiday with our families.

Past year has been globally very unstable and time of the big changes. It feels like everything has changed and we are starting to live in the other world than we are used to do. One of the biggest news has been alerting information of global warming and how fast the climate has already changed and will be changing. We as companies and persons working at the lighting business, we are in the positions where we can do a lot to make our products more efficient and require better quality. That way we can make our part to moderate climate change and help the Earth to save. Our future choices can be a big and important part of this huge and needed change in the world.

We at Arrant-Light Oy have done this year a lot of work to find out how we can make our products more efficient and give them longer lifetime. We have also done many studies and investments what comes to the packing materials. We should think of how we can make them better recyclable and how we can avoid using the unnecessary plastic on it. It is a benefit of all of us, that we try to use every day higher quality, higher efficient, and eco-friendly parts and components in our products. I hope that in the future we can have together open discussion of these topics and make together our products all the time better and better and that way get them meet today’s environmental requirements.

As many years earlier, we have used our Christmas present funds for the Save the Children Organization. Donated funds will be used for local young people who need economical support to finish their studies and help them to go forward in their life.   
It is again our pleasure to thank all of you for the past year 2018 and for the good co-operation.

I wish You a peaceful Christmas Holiday time and all the success for coming Year 2019.
