Cheap and easy: search ebay for LED strip. You want the ones that look like actual LEDs encased in rubber, not the semi-led strips. Should cost around $1 shipped for a 12" strip. It comes with two bare wires sticking out of one end. Find an old 12v cell charger of 1 amp or less and wire it up. I don't think it matters which wire goes where. Plug it in. I did that on my reef tank and it lit the tank very nicely for several years and it was even exposed to salt water splashes. I just left it on all the time so no need for a timer either.
