in that thread linked to the guy with six bulb tek fixture, he had no white light, just purple, green, and pink. maybe it just looked like this but i am looking for the best 4 bulb configuration for a t5 fixture and can agree with going with no actinincs but i was thinking i needed 10000k spectrum. what do you guys think would be the best 4 bulb t5 config. to keep sps?
