The module automatically switches between trailing edge and leading edge dimming modes depending on the load connected, supporting 10-150W incandescent, 10-150W mains halogen, 10-150W low-voltage halogen with electronic transformers, and 5-150W dimmable LED lamps.\u003c\/p\u003e\n\u003cp\u003eInstalled as a single-gang grid module within a modular grid plate assembly, the dimmer operates via push on\/off and rotary dimming control. The rotary dial adjusts brightness smoothly across the supported wattage range, while the push function provides hard on\/off switching independent of the dimmed level. Two-way operation means the dimmer can be controlled from a second switching location elsewhere in the circuit, making it suitable for staircases, hallways and rooms with multiple entry points.\u003c\/p\u003e\n\u003cp\u003eThe module includes overload and over-temperature protection to prevent damage from excessive load or prolonged high-temperature operation. An integrated Inrush Current Limiter reduces the effects of high start-up currents when switching on high-wattage or multiple lamps. The white finish on the rotary knob and push plate matches Knightsbridge's matt white grid plate range. The module requires a 35mm minimum back box depth and fits grid plates supporting 25mm module width.\u003c\/p\u003e\n\u003cp\u003eKnightsbridge recommends using no more than 10-12 individual lamps per dimmer to maintain consistent performance, and advises checking lamp manufacturer specifications before pairing dimmable LEDs with the module, as not all \"dimmable\" LEDs respond identically to trailing or leading edge control.\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.
