1 Gang 2 Way Push-on/off Intelligent Rotary Dimmer - 100-1000W.

The V+ series dimmer switch, designed for all incandescent lighting circuits, including mains or low voltage halogens. This dimmer is recommended for use with halogen loads. The soft start feature gently increases the power supplied to a lamp when the dimmer is first turned on, allowing the lamp to warm up gradually, reducing failures caused by stress on halogen lamps when they are switched on. 

This switch is suitable for:

• mains voltage incandescent lamps 
• GU10 or similar good quantity halogen lamps 
• good quality dimmable low voltage lighting transformers

This switch is not suitable for LED lamps.
