dimmable cfl/ccfl in 4 inch cans
We asked our contractor for dimmable CFLs, and they installed a handful of 4" Lithonia Lighting L3R cans. The problem is that they can't seem to find bulbs to fit them, since the dimmable bulbs tend to be longer than others. It looks like a bulb would need to be shorter than 4" long to fit inside the can (and I assume we'd probably want it closer to 3" so you don't see too much of it).
They tried out a couple dimmable CFLs and they both stick out of the end considerably. Neither of them dim very well (I'd say less than 50%), and one of them routinely decides it would rather be a strobe light.
Any suggestions for bulbs that would fit these fixtures, give good light, and be dimmable? I hear that CCFLs tend to be smaller and give better quality light, though I haven't been able to find one shorter than 4".
