Yeah, another Googler. I am oe but I do not drege up decades old posts,
I
just use it because...

But the thing is you are really not supposed to din halogen lamps
because
then the halogen is not sufficiently activated to allow the filament to
operate in the higher range, which is the whole idea of halogen lamps.

Its all about the; "halogen cycle" - vapourised tungsten recirculates and
condenses back on the filament. Under a critical temperature, it deposits
on
the inside of the envelope just like regular bulbs.


but slowly. And when full powered it then cleans itself.


You'd have to get the quartz envelope seriously hot to do that - like
glowing so white it gave off UV.


AIUI they're self cleaning at rated voltage.
