Can't quite think this through. Work has just fitted a 23W CFL in an
Anglepoise type desk lamp, replacing an 11W - I asked for a brighter bulb.

I've noticed that the shade gets very hot - maybe a little less than a
CH radiator. But still hotter than I would expect. I've also noticed
that the sticker inside seems to indicate CFL max 11W, and incandescent
max 60W.

I've pointed all this out to them, but the thinking seems to be that if
it's OK for 60W, then 23W will be fine, and they can't explain the 11W.

Is this about right? Work asked me to tell them if it gets worse - but
short of burning the building down, I'm not sure what sort of thing I
should be looking for.

Slow work day . . . :-)

CFLs will have a vastly shortened life is the electronics in the base of
the bulb get too hot. Hence the CFL rating given on your fitting. A LED
might be a better bet.
