Costco has a special on Feit LED utility/shop lights... 3700 lumens / 38 watts / 4100k / $32
Great bang per buck compared to other current LED options. I got nine for my little 288SF man cave... 116 lumens per SF.... what an enormous difference.
I have them "temporarily" staged while I figure out what to do with the ceiling. They're very light weight and easy to install/position and include a short small steel cable for hanging.... currently attached to a zip tie around the rafters on each end.
I peeked inside one and the tubular housing is a diffuser shaped to look like an icky $16.99 T8 fixture... it could've been a narrow sleek 1/2" thick panel.... ah well.
