The dimmer comes pre-set to trailing-edge mode, which provides smoother dimming performance with most modern LED bulbs, and can be manually switched to leading-edge mode via the front control knob for compatibility with older incandescent and halogen lamps.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential installation in living rooms, dining areas and bedrooms where dimming control is needed, the dimmer fits a standard 25mm minimum back box depth and uses a screwless cover plate that clips onto a separate metal sub-frame. The matt black finish provides a low-sheen surface that pairs with contemporary and industrial interiors, and the matching black dimmer knob sits flush with the faceplate when fully rotated down.\u003c\/p\u003e\n\u003cp\u003eThe front-facing control knob allows for manual adjustment of minimum and maximum brightness levels (trimming), mode switching between trailing-edge and leading-edge, and factory reset if the dimmer needs to be reconfigured. Built-in protection includes overload protection, overheat protection and an inrush current limiter (ICL) to prevent damage from sudden current spikes when lamps are first powered on. The dimmer is constructed from premium-grade steel with an IP20 rating for dry indoor use.\u003c\/p\u003e\n\u003cp\u003eFor consistent dimming performance, use lamps of the same brand, model and wattage on the circuit. Mixed lamp types or wattages on the same dimmer can cause flickering, uneven dimming curves or premature lamp failure.\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.
