The spectrum issue is exactly why I went with 3 different "white" LEDs. I'm also running two different royal blue LEDs (XP-E and XT-E). They give off slightly different spectrum. It's still not the same as a t5 bulb, but I am definitely covering more than the cool white and royal blue builds that seem to be popular. Eventually, I will add a few oddball colors like red, green, etc.
