so i have 2 different sets of 1k watt dimmable balasts . On the cali balasts it goes 500-750-1000- and super lumens. On the 2nd set of balasts it goes 400-600-1000- and super lumens. I was planning on running all 4 at 600 dimmed down on my 1k hortilux hps bulbs. Now 750 isnt 600.. so its 750 watt equivalent? Whats the draw on power g9nna be like basically 750 watts and 600 watts actual useage? As of now i been running 2 1k hps bulbs so adding 2 more light set ups and dialing everythong to 600 and 750? I hear 600 watt is more efficient lumens at about 90k and 1k is only at 120k gove or take a lil bit. But with 750 what should i be expecting? And is that 500 option means 500 watt? Thank you for any input.
