I just put up a 24X24 shop with 10ft walls, white metal ceiling with metal 3' up on the side walls then wood siding the rest of the way to the ceiling, also with concrete floors.. for lighting I put up 4-(sets of 2) 4ft T5 H.0. lights.. obviously you would need a few more sets of lights but the T 5's put out a ton of light.. they are a 2 bulb light and since my ceiling is white metal I bought just the light, i didnt need the reflective shroud. I got each set for around $26, works great.. and I wired 2 TV hook-ups along with surround sound before I had the foam blown in..its a great spot to have a few beers and work on the sleds or quads
