We find that the curly fluorescent bulbs, as someone above called them, do poorly in situations where heat collects, lasting a few short months (2-3). Some of our fittings are flush with the ceiling, and CFLs won't fit; and we have returned to the old style incandescents for those. Replacing these fixtures would be expensive. The CFL packages say they have short lives in heated situations, which seems to be the case in many fixtures.

I know of no U. S. or Canadian made CFLs. The ones we have are mostly made in China, but I think we did have some made in Mexico. None has lasted over a year, so they are proving expensive.

The 5 year claim is nonsense. We find it is troublesome to try to get replacements under the guarantee and have stopped trying.
