Bud i get what your saying. I really would like to get a 1000w w/ switchable ballast and nothing less, but for the amount i have invested in what i got i am pleased so far. Maybe after i can budget some more money to my garden i'll step up, but I have so many hobbies i can't really have everything all at once, plus support a family of five. Besides the max height of my cab is 4' and 1' of which is container height. So all the light needs to do is penetrate 3 feet. Also the tubes are overhead w/ cfl dangling around penetrating the canopy from the sides.
