Make an Efficient 40 watt Electronic Ballast Circuit
From my experience the ballast uses some of the power but it somehow pushes more power in to the lamp no matter it's rating. Sort of like pushing a 120v incandescent bulb at 140vac instead of 120vac, it's brighter and uses more power but won't last as long. I also have some "green" shop light and it uses 65w no matter what 4 foot tubes I put it in, I tried the stock 40w, 32w and even a 28w and the kill-a-watt said 65w no matter which one was in there. the 28w tubes looked the brightest, but there wasn't much difference.
