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.
100W lamps aren't bright enough, even if I get the brightest ones available. (and they may be disappearing soon too) I've stocked up on them anyway while I can, but that's not the direction I wanna go.
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? This shouldn't be that hard, but I'm not sure anybody makes an adapter like this. Maybe I should be looking for replacement sockets...
