i did this with a 65w"500we" cfl socket with a 105w "1000we" cfl bulb. it burnt my bulb. im guessing it would do the same with a hps bulb but maybe a fire at the end.... thats just my guess. i wouldnt do it.
ok so i got a light mover and a bulb today plus what i had a sun system and remote ballest. i got a 5.5x7.5 ' closet going to use 4x7 for grow area. any idea would be great still need to figure out what type of system im going to run
