Re: Buzzing sound with GU10 (mains halogen) fittings

["Simon Coates" <ecolume@xxxxxxx>]

Chris,

The lamps are 'ringing'.  The filament is resonating because of the
modified
sinewave from the dimmer.  Change your brand of lamp.  Use
either
Sylvania/Osram or Philips, or other decent branded lamp.  Lamps
ringing was
very common years ago, esp. RO80s reflector lamps.
You could also change to low voltage fittings and lamps - this would be
much
cheaper in the long run.

Regards

Simon
