Gunmetal grey 1G LED dimmer with gold diamond etched knob. A stylish and modern dimmer plate, not your usual finish. This is an anthracite gunmetal and is very unique. The striking diamond etched contrasting dimmer knob really sets it off. These are screwless so the front plate clips on and hides the fixings. They are also flatplate so you will need 35mm deep recessed back boxes to fit these flush. The LED dimmer module supplied is trailing edge and rated to 150 watts of LED. It includes a small mechanical potentiometer to adjust the dimming range. They are a very good quality dimmer and work with a wide range of dimmable LED lamps. They will dim my entire range of LED lamps.
