The dimmer supports both trailing-edge and leading-edge dimming modes, selectable via a front-mounted switch, making it compatible with most dimmable LED, halogen, and incandescent bulbs.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential lighting control, the dimmer suits living rooms, bedrooms, and dining areas where variable light levels are needed from a single wall switch position. The push-on\/push-off rotary action turns the light on or off at the last-set brightness level, while rotating the cap adjusts brightness smoothly across the full range. Pre-set in trailing-edge mode for LED compatibility, the dimmer can be switched to leading-edge mode for older halogen or incandescent loads using the front knob.\u003c\/p\u003e\n\u003cp\u003eThe smoked bronze finish is a dark metallic pewter tone that sits between brushed steel and aged bronze, pairing well with industrial, contemporary, and transitional interiors. The screwless cover plate clips onto a separate metal sub-frame, leaving no visible fixings on the wall once installed. Built-in overload protection, overheat protection, and an inrush current limiter prevent damage from transient current spikes when bulbs are switched on.\u003c\/p\u003e\n\u003cp\u003eFor consistent performance, avoid mixing different lamp brands, wattages, or technologies on the same dimmer circuit. The dimmer requires a 25mm minimum back box depth and fits standard UK wiring layouts with screw terminals for live, switched live, and earth connections.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e87.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e87.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e4.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e21.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.

Leading-edge mode suits older incandescent and high-wattage halogen bulbs. The dimmer ships pre-set in trailing-edge mode; the front knob switches between modes if needed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this dimmer control multiple LED bulbs on one circuit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, provided the total load stays within 5-150W for LED and all bulbs are the same brand, model, and wattage. Mixing different LED types or wattages on the same circuit can cause flicker or uneven dimming.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat back box depth is required?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA 25mm minimum back box depth is needed.
