Another use I have seen for these was stores that sell bulk honey.
(where you bring and fill your own container and buy what you need).
There would be an incandescent bulb (unknown wattage but quite bright)
underneath the can near the tap
in order to provide enough heat so the honey would flow reliably in
winter,
or in air conditioned shops.
In this case, the only purpose for the bulb was as a heater.

Technically true as it cannot work on its own, it at least needs a
socket and cable.
Another issue that might come about is that as CFL use becomes
widespread,
we might start seeing more and more light fittings designed and
manufactured
with only CFL in mind, and putting in an incandescent might melt or
burn them from the heat.
The other interesting argument one could make is that 99% of light
fittings that I have seen have
"60w maximum" labelled on them.
About the only safe fittings for 100w bulbs would be naked lamp
fittings without any covering, or specifically deigned fittings -
probably with
ceramic sockets and high temperature cables..
Therefore they could argue that the 100w bulb is indeed a heater as it
can't be used in most lighting applications.
I suppose in that case they could claim that they are a "heatingOn 20/10/2010 2:38 PM, kreed wrote:

Nope, the plastic retaining ring on standard sockets cracks due to the heat
when used with 100W globes for any length of time. I've replaced stacks even
when using only 60W globes and a non enclosed light fitting.
Right.

When you think about it, in any decent sized incandescent a lot of
the filament
heat must travel directly up the metal stems and to the base,
this must heat up the base and socket enormously.
Probably doesn't do a lot of good pointing a bulb upwards as it would
get hotter
without the base to act as a "heatsink" ?
One place I lived in had a 150w (philips) bulb in the toilet light
fitting, &
the socket had gone a funny brownish colour from heat stress and was
replaced. The previous owner
had liked to read in the loo for long periods and due to eyesight
problems, needed a bright light,
even in the day.
I replaced it with something more sensible, as I don't go to the
toilet to sunbake
but I still have that 150 watt "heater" around here somewhere.
