Downsize your luminaire with new HC-series

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
