i have 2 1000w magnetic hps ballasts and like 7 1000w hps enhanced spectrum hortilux hps bulbs. i need to downgrade to at least 600w for my current situation and i was wondering if i got some dimmable ballasts and ran it at 600w if my 1000w bulbs would still work? and if so i heard something about some of the digitals not being compatible with the horti bulbs. any1 kno anything about that?
