I have 3 or 4 of these that I'm going to replace (well, SANTA is going to replace...). As my lights are covered, I don't need the good-looking pendants. They are black Coralvue pendants. They have 400w DE bulbs in them, but I believe they also take 250w DE bulbs. They are in very good condition. They will be inexpensive...
