Other VARILIGHT Dimmers

My dimmer just turns the lights on and off; I cannot dim them.

This problem is usually caused when one of the components in the dimmer has failed, usually due to a plasma. Plasmas can be caused when a mains halogen light bulb (e.g. GU10) fails. For this reason we recommend only using good quality mains halogen bulbs from well-known brand.

If a dimmer exhibits this fault it will need to be replaced.

The best type of dimmer to use with mains halogen bulbs is a VARILIGHT V-Plus IR series dimmer. The rapid on-board overload protection can usually turn the dimmer off so quickly that it survives a spike in the mains supply.
