wow -.- i have 3 bulbs in place 2 120 watt cfls and 1 125 (they ran out of 120's) so according to what you said im way over the 2000 lumens range. Should i stick with one then? the box is about 4'8" tall and my light setup does not shift in any direction. Now that i remember do you know anything i can use as an adapter for computer fans?? ( i hooked one up directly to the power line and fried. (test fan, got plenty more hehe)
