I have 2 of theses lights for a total of 1000watts. With just one oscillating fan I can keep temps to 80F I also just built 2 lights with boards from Photo Fantom Designs. About 200 watts. Theses boards are killing it in veg. @Donaldj I think I tagged you on both of these builds. I think I tag you on everything I do. lol. I hope its not annoying
