I bought these green and white porcelain antique lights in perfect condition on Ebay:
Just installed them today.
I bent some 1/2" conduit with a pipe bender, then threaded, bead blasted, coated with SPI epoxy primer and finished them off with PPG black acrylic urethane. I painted the just the top cap of the fixture black too as it was painted cast iron.
I installed one on the left side wall also but I don't have power to that one yet. I couldn't get the color balance right for this shot because the new light is incandescent and the lights under the canopy are recessed CFLs.
