Recently installed a halogen light fitting with 10 arm x 20w 12v G4 bulbs.
The light switch is a 2 x dimmer (1 for the above light, 1 for 2 x 100w normal bulb wall lights).
When the wall lights are on everything is ok. When the ceiling light is on there is a buzzing noise emitted from the light and also the dimmer does not work effectively - does not respond to dimmer as efficiently as the wall lights.
Can anyone advise (a) what the problem may be, and (b) how to rectify it?
