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.



Halogen has a build in cycle to keep the filament healthy.
That does not work at a lower temperature.
So running it at the wrong voltage will cause it to fail
early.

Why? If there is almost no filament evaporation (which is the case at, say, half
or 3/4 voltage) why would it fail sooner? The halogen thing might not kick in at
low voltage, but then it's not needed.
