Default [Q] dimmer switch for halogen floor lamp

When they are RUN at the rated voltage and power. If you dim them the
tungsten is deposited on the quartz and short of heating the quarts to
white hot (above poster's remarks) the tungsten is going to STAY on the
quartz, not recoating on the filament.

** That is merely one person's opinion, not backed up with evidence.

Wiki says differently :

https://en.wikipedia.org/wiki/Haloge...on_performance

Stage lighting uses dimming all the time with halogen lamps and there is
no blackening or short life experienced - the lamps run much longer as
expected.

The claim that the "halogen cycle" puts metal back on the filament is true
but it does not deposit it back where it came from so has little effect on
lamp life.

Most halogen lamps are low voltage or high powered - so in both cases the
filaments are thicker than typical non halogen examples.


Wrong ....



** So they are actually thinner are they ??


FOAD you ridiculous, know nothing bloody troll.
