Best cheapest option is 315W CMH lights on low frequency square wave ballasts, preferably from Philips. The square wave maximizes efficiency by eliminating the time the lamp spends at or near zero voltage, making them the most efficient option, right up there with DE HPS.Well i dont know if your right or wrong. The lines ive had them gone if i use brightness on my phone. Yea but im cool off LED for now kinda pricey.
If you really want more watts per lamp, the revolution micro DE fixture is best of both worlds; DE power AND low frequency square wave driver, pretty sexy!
