COB Series – UGR<19, Tri-Colour COB Downlight

Ultra low glare, bright and energy efficient.

LED down lights are found everywhere! In homes, schools, offices and retail stores, and so many more applications.

Traditional downlights are usually sporting a 50 Watt halogen light bulb, these lights are notorious for consuming a lot of electricity and this is partly due to the fact that you need a lot of them to get the right lighting effect.
Our Ultra low-glare LED Circular COB Downlight replaces traditional downlights with an LED downlight that includes a transformer. This ensures that there are no compatibility issues with existing transformers.

The technology in LED downlights has come a long way, even in the last couple of years. The LED downlights of today look fantastic and can save a substantial amount of electricity and associated costs.

Get in touch with us today and see how you can start saving all that money with our LED lighting solutions.
