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.
Other then that, for a decoration a dim bulb is no problem,
