Why doesn’t Kichler use RGB in it’s LED accent lights?
Creating white light by combining red, green, and blue is great for certain applications and will definitely be part of the future of white light for general illumination. There are however some weaknesses with this method. First, each LED color degrades at a different rate creating a color shift issue over time that is very difficult to mange. Second the “binning” issues become 3x more difficult to resolve. Very complicated (expensive) electronics are required to overcome these issues. Third, it is difficult to optically combine the three colors well enough not see color separation around the edges. Cannot have beam too close to objects. Lastly, higher CRI values are currently impossible with RGB.
