Bicolor LED lights sound like a great idea. However does mixing dissimilar lights result in high quality color across the entire range of color temperatures? Or will the entire range of light be sub-par from the manufacturer compromising the LED diode in order to make the two emitters mix?
We extensively tested a bicolor LED from a very well respected LED manufacturer to better understand the issues. We measured the CRI (Ra), CRI (Re), TLCI, CQS, TM-30-15, and color temperature to determine how the color quality stacked up across all levels of brightness (dimming) for the entire color temperature range.
The results are very … illuminating!
