Heck LOWES and HD have 2 bulb 4Ft florescent fixtures for as low as $11 each, Purchase those then get the replacement LED bulbs, take out the Ballast, and away you go, I replaced the bulbs in my 2 bulb units and wow, I can see things better than ever, I did not know the Pace could be lit up like that. I got the 5500 -6000K bulbs and the are bright as a full sunny day. I guess if you wanted to you could also get the replacement ends for the florescent fixtures and build you a box and wire it up. The ones I did were set up so both prongs on one end were power and the other was ground. (I actually had to replace the parts on one end as I knocked it off and broke both of them.) from 2 to 4 bucks a pair.
