Led color shift

NettetWhile the tradeoff between color quality and efficacy has remained in the era of LED lighting, a light source efficacy as high as greater than 200 lm/W allows LED downlights to make a nice balance. At a bare minimum, residential recessed lighting should provide color rendering capability that gets close to that of incandescent and halogen lamps.
