It ain't rocket science, but I thought some of you might like to see how I resurrected some old industrial light shades to be new-old lights for my '20s garage. I used off-the-shelf parts from HD, but with some adaptation. A 1 1/2" ferrule was just right to fit through the top opening, but the hex was too big to fit in deep enough to let the threads protrude. My cheapie lathe made short work of the aluminum fittings, cutting down to a cylinder and then turning a taper above it. No great precision required; I just eyeballed it. A locknut holds the shade onto a standard 4" octagon box cover through a 2" hole cut with a hole saw. A flat fixture bracket mounted on two 10-32 x 2 machine screws allows the depth of the socket in the shade to be adjusted. I wanted truss head screws, but settled for flatheads, then had to do the extra step of countersinking. The sockets are really great for this. They're porcelain and mount on the standard 1/8" IP threaded tubes you so often find in light fixtures. The backs are closed, so the connections are protected from the elements (and those pesky insects). And, they're very sturdy. I had to bend the tips of the fixture brackets down at the ends so they'd fit inside the octagon boxes. Normally, they would attach to the cover screws. I used 2 1/8" deep boxes to allow lots of socket depth adjustment. Putting it all together, I was able to put 23W CFL's in deep enough to get them above the rim, so the light isn't shining right in your eyes from across the room. The 44W CFL's I had wouldn't go that deep, but I found some others that have smaller diameter ballasts, and will go an additional 2" or so. I'm going to put 100W metal halides in four of them where I need a LOT of light; waiting on bulbs and ballasts now. So far, I'm really pleased - a big improvement over bare bulbs!
