If you live in a newer home, look up. See those light fixtures your floodlights screw into? I plan on buying 4 of those(all I can fit) and putting them onto my lid. Ill cut the holes smaller than the lip and just seal them on with seal-all. Then I plan on usin a normal 110V screw socked to put in the top for the lights.
So If you can imagine it... the light housing will be OUT and BOVE the box and the very surface of the bulb itself will be just as high as the lid would be.

Also NorCal, I was going to probably use 2 LED's 138Red/30Blue, and 2 of the highest wattage Soft Whites I could find. I got some actual output 26W right now but for that little rubbermaid... I think it'd do the trick. Maybe just ONE LED and THREE CFL's?

Pics are on my scrogging box thread.
