The 40 gal tank is 36" long, so 48" wouldn't fit. I also had a pair of Ho ballasts sitting in the garage unused. These are for "24-96 inches total length". The way the schematic showed, I insulated the yellow outputs, and ran one end of the bulb with red, the other with blue, to configure the ballast for one bulb. It is rated to push 90 watts to 96" total length. Under 72" total length, the power factor is greater than 85%, as well. So, I have a pair of 36" bulbs, one actinic, one50/50, running in theory at 90 watts each. They are very warm to the touch, and the ballasts are running pretty warm. Nothing is terribly uncomfortably hot. I can hold my hand on the bulbs for several seconds before it gets too hot. I'm rather pleased so far. I'll just have to let time do its thing to see how the bulbs last.

Current Tank Info: 40gal, and a 110 gallon.
