So I had an old fluorescent 4' tank light that "hummed", so it got put away... Then I had an idea... Cheap amazon dot com led strip lights (waterproof kind) in daylight white with the 3M adhesive back. I got a 12 foot strip and power supply for just under $20!! Took the old fluorescent tube out of the fixture and ran the LED strip inside the reflector... Wha-Laa... Nice mellow LED in a 4' fixture... I'll see if I can get some pics that show it...
