AAMOI, how do you know they couldn't take a CFL? Is it an electrical
or a mechanical problem? We have two such lights (PIR-operated
bulkhead lights), different designs, and I fitted them both with CFLs
a couple of years ago, no problem.

Might have been triac operated. The CFL load would cause latching and
triggering problems.

OK, but can you tell that by looking at them while walking past on the
street?

Absolutely. I can see any of them quite distinctly from the light
quality, whether
it's walking past them in the street, walking into a hotel room, or
anywhere else.

The one application that I would consider for CFLs is outside,
overnight security
lighting, because basically I don't have to look at the light from the things.
