What part of CFL lamps overheating and catching on fire goes
right
over your head?

It only happens extremely occasionally.


A hell of a lot more often than with incandescent lamps.

More often I've seen excessive heat from an incandescent making the
fitting
brittle, the danger not being fire directly, but the fitting collapsing
later
on.

A lot of incandescent fixtures are not designed for safe operation of
CFL
lamps.

Explain.


You really don't know anything, do you? Some fixtures hold in the
heat. The incandescents & ceramic sockets can handle the heat, but the
thermoplastic in the CFLs melt, the electrolytics overheat and they
fail, or catch on fire.


When I first started using them about 17 years ago, I thought I had
a few light fixtures that were way too hot, and I worried about that.
By using CFL's I would be usinf less electricity and the fixtures were much
cooler.
If it was an incandescent fixture in the first place, they automatically
hold a fire for a very short period and suffocate it usually. I would worry
more about CFL's NOT in fixtures, I have one CFL in the front yard 24/365
and it probably gets real hot in the summer day, but so far its going
without
problems. Fully air sealed anyway.

Why do you have it on on a hot summer's day?



Cause I don't turn the switch off and on. I just leave it.
I do have parts to update my front lawn post including some spots
to illuminate some trees, and they will have a photo switch. I hope
the switch works on CFL's. I was going to check if this switch used a relay.

I don't need to illuminate my front lawn, there's a bloody streetlamp there!

When I eventually get round to building the pond and lighting it, I may have to
black out that side of the streetlamp (it's the old hemispherical dome
variety).


The trouble with street lights, only 10% of the light hits the street.
The rest just blinds you.
