Can a dimmer be used with halogen lamps?
You can use a dimmer with a halogen lamps but some low voltage halogen lamps require a special dimmer. Particles from the filament in a halogen bulb will cycle from the filament to the inside of the quartz envelope and back while in operation. Halogen bulbs used on a dimmer will last longer if they are set to full “ON” for two minutes before being turned off — this helps the particles from the filament complete their cycle.
