NO.
Using LEDs in an EM can get a lot of reactions both ways, and that's understandable.
What i cant for the life of me figure out is how people are advising you to pay 150 dollars for this shit, recockulus.
Go to comet and buy bulk warm white [or sunlight..whatever) and do it for way cheaper.

Spoilers, paying someone to color match every insert is a total waste
Edit: I ASSume these are all 44s like EMs, so im looking at a picture and there cannot be more than 50 insets so fuck it, let's color match.
3-4 red, 3-4 yellow, 15 (tops) white, 10 green (assuming all rollovers ares green. Large guess 25 white for GI, large guess 25 for Backbox (remember when using LEDs in the Blackbox its not needed to fill every socket, it'll be too bright).
I got like 88 lights there which is probably too many; at 69 Cents a pop. Whilst I am a scientist math is not my field, but I dont know how we get to $150.
