i have a digital ballast, and i blew my first hps bulb, it was a $100 eye hortilux at that.. now. i'm only sticking with digilux and i have also heard good things about sunpulse.. sunpulse are mh's that are made for digital ballasts.. i know you said you don't need a mh, but these bulbs come in all different k ratings and you just pick the k that you need for that stage of growth.. i have heard some really good things about these bulbs, and think that is the way i'm going to be going in the future when the funds are there... i used an mh bulb for flowering in this grow, and i have to say, i think you get much better resin production from mh's than you do with hps bulbs do to the increase in uv light output from mh's..
