There are many situations where halogen lamps are dimmed successfully.

** Not many - ALL !!

I won't gainsay any of your other remarks. But I've seen this.

** Maybe you have seen a QI lamp fail early - so have I.

No, it's apples-to-apples, as I said.


** Blatant lie.
The mogul-base floods were just like really big, ordinary incandescents.


** My properly detailed example proves you wrong.

Dickhead.

It isn't a perfect solution, because otherwise the bulb would never fail.
So what? The numbers are as I posted--about a 20x lifetime increase.


** Shame the QI lamp example I posted PROVES you wrong.

You're out of your depth on this one,


** Fraid you have already DROWNED !!

What a pathetic fake and damn liar.

**** off.

Have a 10Watt, 12Volt Hologen lamp for a christmas decoration. But the
mains tranformer I have is only 6 Volts.

Apart from being a bit dimmer, would there be any other consequences running
at the lower voltage? Thanks.

it should work properly. Sure it's darker, but this may be ok for
cristmas decoration. Your lamp lives longer running with lower voltage.

Greets and happy holidays.

Consider theatrical halogen lamps, anything from 500 watts to 2000 watts
run at anywhere between 3% and 100%, tho it's rare for some instruments to
ever be run at full stick for any length of time, some lamps can be at
less than full voltage for hours on end.

The lamps last just fine ( I have some which have been in service for 10
years or more (HPL575))


** Plus the BILLIONS of 12V QI downlights that use dimmers at any setting
the owners like.
