These are my old burm cages. I was looking through my photo archive to try and find good pics of the caging I had around the light/ceramic bulbs. This is the best pic I could find. At the far end is a 250 watt ceramic, in the middle was a 100 watt white light and at the end was a 100 watt black light. The caging around the 250 watt ceramic bulb were made to the specs that came along with the bulb. I think it was about 2 feet down from the top and about 18" across........I would have made it smaller than that though.
If I find a better pic I'll post it. The pic was taken on Dec 10, 1999.
