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:
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.
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
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.

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
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
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
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
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
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
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
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
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
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.

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.
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.
– 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.
Do you want know more about the Lifud drivers and what we have in our selection? You can visit www.lifud.com to see the whole selection. Send a request about the products to firstname.lastname@example.org or by calling +358 20 246 2300
Have you read our blog about the sustainability of our components? You can read it here.
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
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.
Below you can download datasheets about our linear LED modules.
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.
Generally, we can say that LEDs are environmentally friendly and recyclable. They have a long lifetime and low power consumption. They don’t contain hazardous substances, for example, mercury as compact fluorescent lamps do. In this blog post, I will present to you four environmentally friendly luminaire component choices.
LED That Don’t Need a Driver
Have you ever looked inside the driver? In the picture above, you can see the inside of the small-sized one. Drivers are made of many different materials and components. That’s why they are hard to recycle. The fewer components product has, the easier it is to recycle. For example, an aluminium heatsink is easy to recycle, because it contains mainly aluminium.
Drivers are the most fragile parts of the luminaire. In general, they can be the first component that breaks from the luminaire.
All traditional LEDs needs a driver to work. Except for AC COB that can be connected straight to the mains power. Because AC COB doesn’t need a driver, luminaire can be a lot smaller than before. This gives more flexibility for the design. At the same time, you can save in logistics and packing. You can read more about AC COB from our blog post.
Same Lumen Output with a Smaller Luminaire
Size is an important feature when designing environmentally friendly luminaires. When you use less material the luminaire gets smaller. And by downsizing the luminaire you can save in logistics and packing.
One great way to make the luminaire smaller is Citizen’s HC COB. It has higher efficacy and lower terminal resistance. This means that you can use a smaller heatsink. Therefor luminaire gets smaller the and you can still get the same lumen output. As a result, it makes HC COB more environmental choice. Read more about HC COB from here.
The Right Amount of Light and Less Light Pollution with Right Optics
When we talk about LEDs, often we come up with light pollution. We can say that almost all outdoor light that doesn’t have a purpose is light pollution. This means that light always needs a target.
When you replace the old light sources (for example HPS-lamps) with same powered LED, you get a lot more light. This is not environmentally friendly. You get a lot of unnecessary light and same time create light pollution.
When we design luminaires with the same lumen output than before, LED saves energy. This is because LED has less than 10% of the incandescent lamp’s power consumption. That’s why it is important to think about lumens, not power when replacing lamps with LEDs.
LEDs light comes from a very small area and from a flat surface, so it is easier to control than a light bulb. In street lights, most of the light pollution comes from light that goes up and away from the road. It is important to choose optics for the luminaire which are designed to minimize the light pollution.
Control the Luminaires with Sensors
There’s a lot of different sensors for different applications. The most familiar ones are the on/off-sensors. They automatically switch the light >on and off by movement. They save energy, as the light can never be accidentally left on. This type of sensors is already generally used in public spaces.
Another great way to save energy is to use daylight sensors. They react to the light that comes from the outside. This way you can maximize the benefits of the sunlight. For example, during the day, you don’t need as much artificial light as in the evening. Read more about sensors from this blog post.
We have already made big steps in ecology, but still, we have a lot to do. We need to think about the packing of the luminaire and logistics. It’s important to minimize the amount of plastic used in packing. Also, we need to think alternatives for air freight. Small choices really matter.

Nowadays LEDs have great efficacy and lifetime. They produce more and more light with less power. I think that it’s less important to increase efficacy because we have already reached what the market demands. What else we need from the light than a lot of lumens? In this blog post, I’ll compare the differences between white LEDs.
We all know that LEDs are available in different color temperatures. For example, Citizen 6 generation’s LEDs are available from 2700K to 6500K. They are also available in different color rendering indexes. Color rendering index simply means how well a white light source can show, or render, colors compared to sunlight. We know that the color rendering index does not always tell the whole truth (You can read more from this blog post).
Nowadays we need a light source that has good efficacy and color rendering, and it doesn’t hurt if the light source can be customized to use in many different luminaires. We want light source that brings colors vivid and alive. Also, design interiors with relaxing atmosphere.
Let’s look into what else affects the quality of light than the color rendering index and color temperature.
White without greenish tone
IMAGE: Black line in the picture is B.B.L. Red circles indicate below B.B.L. LEDs.
In some projects, we want a light source that makes white look whiter. Some LEDs may turn white into light green. Traditional white LEDs’ color temperature chromaticity is on or very near B.B.L. (Black Body Locus). Citizen also produces below B.B.L. LEDs. Their color temperature is below the B.B.L. line. As you can see in the picture, above the line is greenish colors and below the line is reddish colors. Below B.B.L. LEDs make white look pure white and it also renders red colors better. This way we can create light that doesn’t have a greenish tint.
Below B.B.L. LEDs are very popular in shop lighting and everywhere where brisk atmosphere is needed.
The general color rendering index (CRI) is defined as an average of the sum of first eight R-values. However, these first eight indexes are rather less saturated colors, while indexes R9-R12 represent highly saturated colors. This means that the same CRI doesn’t mean same color rendering.
The Citizen’s Vivid LEDs make colors seem brighter with better color contrast. The spectrum of light has been designed to have as good as possible saturation. This way Vivid LEDs can render bold colors vividly. With better saturation, you can read easier for example newspaper under the Vivid LEDs.
Below you can see a picture where Vivid LEDs are compared. The higher the bar is, the better the color renders. The comparison is done to halogen bulb (0= halogen bulb performance).
Great use for Vivid LEDs are places where good color rendering and concentration is needed, for example, clothing and cosmetic stores, art galleries, schools, hospitals, and offices.
There are two different Vivid LEDs:
Brilliant Vivid – Very high color contrast.
Natural Vivid – High color contrast.
Vivid LEDs are meant to be combined. Use Brilliant Vivid as spotlights to bring color and textures up, and Natural Vivid as base light because it has better efficacy but has still very good color rendering and contrast.
Change the color temperature of light
Everyone is now talking about “human-centric” -lighting in the lighting industry. It means that by changing the color temperature you can maximize productivity and improve concentration or create comfortable atmospheric feeling. Citizen’s Tunable White is a great solution for “human-centric” -lighting. Its color temperature can be changed freely from 2700K to 6500K. This means that you can achieve warm light like incandescent lamp and daylight with only one module. In addition to changing the color temperature, you can also dim the brightness.
Early Tunable White products have been big sized modules. Citizen’s Tunable white is as small as the COB. This means that you can make a lot of smaller Tunable White luminaires than before. The small size also gives more even light. The spots between cool and warm dies are practically invisible, which guarantee more smoothly light.
By connecting Tunable White into the right control unit, you can change the color temperature and brightness according to the time of day.
Light that gets warmer by dimming
One of the features of the halogen lamp is that when dimmed its color temperature changes warm-toned. Citizen’s Dim-to-Warm COB-LED does the same thing.
Dim-to-Warm is a COB-LED, so you don’t need any complicated special features from the driver, like two-channeling or programming features. Ordinary triac dimmable driver is enough. Dim-to-Warm COB has preset dimming curve, so when you dim it, its color temperature changes automatically just like halogen.
I hope that this blog post gives you some new thoughts for designing the luminaires. When you use any of the LEDs that I just presented to you above, you’ll get a luminaire that has more to provide than just ordinary light source. This way you can have competitive advantage.

New series of LED, Citizen High Current COB LED is now available. What is High Current COB LED or in other words HC-COB? What new possibilities does it give to us? I’m going to tell you all that in this blog post.
HC-COB is COB that has same LES and package sizes as the previous Citizen generations. Compared to previous generations the HC-COB has higher efficacy and Tc and wider wattage and lumen range.
With new Citizen HC-COB, you can achieve lots of great advantages compared to previous LED-generations. You can downsize luminaire or get more lumens with the same size of the luminaire. So, there’s a possibility to use it in different ways. Let’s get into that.
Downsize your luminaire
Luminaire downsizing has become a trend in the luminaire industry. Nowadays luminaire size must be as small as possible to design luminaires that are cost-effective with less visibility. In public spaces, track lights are in general use. When you downsize those luminaires, you get space that is more spacious and airy.
HC-LED has higher efficacy and maximum Tc. So, you don’t need so large cooling system with it. This means that you can use a smaller heatsink to downsize the luminaire. Same time you can reach same lumens as today.
Luminaire downsizing means that you can make big savings, for example in aluminum, logistics and packing. As a result, it makes HC-COB more environmental choice.
At the same time when luminaire gets smaller, you can reduce system cost of luminaire. Smaller heatsink is cheaper than the bigger one. And as I said before, we can make big saving in packing materials and logistics when luminaire gets smaller. See the diagram below about how you can save in luminaire system cost.
As a result, you can make lighter and cost-effective luminaires that are more environmentally friendly.
Here’s an example of luminaire downsizing. In this example, we are changing COB version 6 to HC-series. The result is that you can get even more lumens with less LEDs.
Get more lumens from your luminaire
What if you don’t want to downsize your luminaire? Do you want more lumens with the same luminaire? With HC-COB that is possible too.
When you keep the same heatsink or luminaire design and just change the LED to HC-COB, you can get more lumens. This gives you more lumen package options and flexibility in one luminaire design.
Let’s see an example if COB version 6 is replaced by HC-series.
As shown above, you can get even 17,8 % more lumens with HC-COB.
What kind of lumen packages does HC-COB offer?
2700K, 3000K, 3500K, 4000K, 5000K and 6500K
Ra70, 80, 90, 97 and Below BBL
Lumen range from 500lm up to 77 000lm
Same size than previous COB generations
