Description
Generation 2 CHM-9-XH20 LED High Density White COB Array
Luminus Chip-on-Board (COB) LED series offers a complete lighting class solution designed for high performance illumination applications. The selection covers a wide lumen range from less than 400lm to over 25,000lm, all major color temperatures and can deliver color rendering greater than 95 at 2700K and 3000K and R9 greater than 90. These breakthroughs allow illumination engineers and designers to develop beautifully lit spaces without sacrificing efficacy, brightness and overall quality.
