I've done this with some lettuce lights for my vegetarian wife but now need to do so for some garage with lights.
Why not but more tubes? The quality is bad, the 3 tube lights from HD are 40$ and flimsy (but have awesome reflectors) and they're larger.
I have a number of Philips ballasts, 4x. I had planned on driving them at 2x (1 ballast runs 2 tubes, doubles up)
Running a kill-a-watt meter shows nominal consumption at 75 watts, doubling 1 tube takes it to 85 watts. Doubling both tubes is 95 watts. Quite a bit under what I expected. Ballast factor is only 0.89
Photos of the ballast are attached. Reading up on how they are designed it looks as if the reactance capacitance would need to be modified of I wanted to push more than 250ma.
Reading the parts here.. Any suggestions where to mod? I haven't found anything on the web about modifying the ballast itself.
