950? Is that because of the bloom stimulator? I'll have to go check my ballast....I know it's not digital but it does go back and forth from hps/mh. I remember asking at the time whether I should go with several 600's vs 1000 for my room (8 waterfarms) and he told me 1000 was better than several lights and I'll be damned if I remember the why. I also asked him about conversion bulbs etc and the discussion came down to the best way to go. In his view the best way to go was 1kw switchable and i don't remember digital entering the conversation.

PS....mine is 120v
