M/H lighting
Are DE the way to go for M/H? I have read that 150w DE are brighter that 175w mogul type. Would a 150w DE be good on a 90 gal tank then as a two lamp setup? Just dreaming about M/H again. I am still worried about heat and the noise of fans. Last question, how do you match ballasts with lamps? I have read too much that it is getting confusing.
thanks for any info.
