The lights in our church are incandescents on dimmers. 150W light bulbs
cost $3 apiece and only last 750 hours (weren't they $2 just a couple of
months ago?) and these lights are in enclosed fixtures and *really* hard
to reach. Little screw-in halogen capsule lights are slightly more
efficient, cost $6, and last 2000 hours. I also suspect traditional
150W lamps will get expensive and/or hard to find soon.

So I'm looking for bushings to screw into medium-base Edison light
sockets to adapt them to single-ended halogen lamps. I've seen
medium-base to candelabra adapters, but this is a "mini candelabra"
thread, not normal candelabra base -- also it needs to be temperature
rated for at least 150W lamps. Any idea?
