The module switches automatically between leading-edge and trailing-edge dimming modes depending on the load type connected, supporting 10-150W for incandescent and mains-voltage halogen lamps, and 5-150W for dimmable LED lamps. The rotary knob provides dimming control while a push-action on the same knob switches the circuit on and off.\u003c\/p\u003e\n\u003cp\u003eDesigned for installation into Knightsbridge grid plates (Screwless, Flat Plate, Raised Edge, Metal Clad), the module occupies one grid position and requires a minimum 35mm back box depth. The 2-way configuration allows the dimmer to be wired in parallel with a standard 2-way switch elsewhere on the circuit, so the lighting can be controlled from two separate locations. Overload and over-temperature protection cut power automatically if the load exceeds the dimmer's rating or if internal components overheat during operation.\u003c\/p\u003e\n\u003cp\u003eThe anthracite finish is a dark grey with a subtle metallic sheen, sitting between matt black and brushed steel in tone. The module's steel and ABS construction provides durability in residential and light commercial installations. An inrush current limiter inside the module manages the initial surge when multiple LED or halogen lamps are switched on simultaneously, reducing stress on both the dimmer and the lamps. Knightsbridge recommends limiting the number of lamps on a single dimmer to 10-12 units to avoid inrush current issues, even if the total wattage remains within the 150W maximum.\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\u003e56.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e23 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e22 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
