Im an oldschool hid light user....this technology has me dumbfounded in a good way. 42" above! Now that's a light man!
hey man, i still use my magnetic ballasts and batwing reflectors, i keep it oldschool, lol...i hate spending money on something if its just an upgrade to something i got that already works...pulling 6-8k out my ass for new lights, i might as well wait to set a new spot up and then splurge lol..i guess ive done that enough in the past and learned my lesson, im not making money if im spending it lol
ive heard of ppl getting away with 30-36" above canopy just fine, room environment will play a huge role...
im still holding out for the bml spydr 1200 to come down in cost, it out produces
gavita per 4x4 area, and takes about 400 watts less..also count in the less cooling you will need
