Description

The Knightsbridge CL2191PC is a 1-gang 2-way intelligent dimmer supporting loads of 10-200W for incandescent and halogen, or 5-150W for dimmable LED. The dimmer uses a rotary knob for both on/off control and smooth dimming adjustment, housed behind a polished chrome rounded-edge faceplate with a matching chrome dimmer cap.

Designed for residential lighting control where dimmable bulbs are installed, the unit supports both trailing-edge and leading-edge dimming modes, with trailing-edge set as the factory default for LED compatibility. Mode switching, trim adjustment and reset functions are accessible via a front-facing button on the rotary knob, allowing the dimmer to be reconfigured when bulb types or fittings change without removing the plate. The 2-way configuration supports control from two switch positions, typical for stairwells, hallways and rooms with multiple entry points.

The polished chrome finish provides a mirror-like reflective surface that suits contemporary and classical interiors where chrome hardware is already present. The rounded edge gives a softer profile than square-edge plates and sits closer to the wall at 7.5mm projection. Built-in overload protection, overheat protection and an inrush current limiter prevent damage from transient loads when bulbs are switched on. The dimmer fits a standard 25mm minimum back box depth and connects via screw terminals with an earth connection required.

Knightsbridge recommends using the dimmer with a single lamp type per circuit — mixing different LED brands, wattages or lamp technologies on the same dimmer can cause flickering, reduced dimming range or incompatibility. Where a lighting circuit contains multiple lamp types, a broader-compatibility dimmer or separate circuits may be needed.

Frequently Asked

What bulbs is this dimmer compatible with?

The dimmer supports dimmable LED (5-150W), halogen (10-200W) and incandescent (10-200W) bulbs. It ships pre-set in trailing-edge mode for LED compatibility. Leading-edge mode is accessible via the front button for halogen or incandescent loads. Not all LED bulbs are dimmable — check the bulb packaging before use.

How do I switch between trailing-edge and leading-edge modes?

Press and hold the front-facing button on the rotary knob for approximately 3 seconds until the dimmer cycles to the next mode. The mode can be toggled between trailing-edge (for LEDs) and leading-edge (for halogen/incandescent) without removing the faceplate. Refer to the Product Specification Sheet linked above for full instructions.

Can I mix different bulb types on the same dimmer?

Knightsbridge advises against mixing different lamp brands, wattages or technologies (e.g. LED and halogen) on the same dimmer circuit. Doing so can cause flickering, reduced dimming range or incompatibility. Use a single bulb type per dimmer for reliable performance.

What back box depth is required?

A 25mm minimum back box depth is needed. The faceplate projects 7.5mm from the wall once installed, giving a low-profile finish suitable for most residential installations.
