I've got a 2 bulb 48" setup that I retro fit into a dual flourescent AGA strip light. It has the bulbs (2 months old), waterproof endcaps, reflector all housed in the strip light fixture. The ballast is long gone though, you can get a ballast for $35 from Hellolights http://www.hellolights.com/22elarovhoba.html and it will fit in the enclosure just above the reflector.
It's very easy to wire up I even have extra wires, screw caps and the ARO ballast comes with instructions.
