-Two four foot long LED shoplights (At least at my local store they're now selling a Honeywell model with a slightly higher (4500 lumens) light output.)
-Light socket adapter with two outlets
Total was roughly $80 with tax.
In the picture above I also bought longer hooks just in the case the ones that were included weren't long enough to go through drywall and "bite" enough into the stud but I didn't need them.
Installation was easy. I used a stud finder to find the studs in the ceiling, drilled pilot holes for the hooks, screwed them in and mounted the lights. I mounted one in the front and one in the rear centering them as best I could. Using the light socket adapter greatly simplified installation as instead of having to hardwire them in I just needed to plug them in. They also work with the existing light switch this way. The plugs on the lights are grounded so I needed the three prong to two prong adapters in order to plug them in. The cords aren't very long so I used one extension cord as well.
Before. (Excuse the mess. Putting up a shed to get a lot of this stuff out of the garage is next on my list for the spring.)
After. As usual, the pictures don't totally do it justice but even my wife was impressed with the difference.
