Description

The Knightsbridge 2-gang 2-way leading edge dimmer supports 40-400W incandescent loads or 3-100W LED loads per gang, with push on/off operation and rotary control for each circuit. The white square edge plate is moulded from thermoset resin with a 9mm projection and anti-microbial properties tested to ISO 22196:2011, making it suitable for residential and commercial installations where hygiene is a priority.

Designed for two-way dimming control from two different locations, the dimmer allows a single lighting circuit to be dimmed from either switch position. This configuration suits staircases, hallways and larger rooms where control is needed at both ends. The leading edge dimming technology works with resistive incandescent loads and compatible dimmable LED bulbs, though compatibility varies by LED manufacturer and model — always check with the bulb supplier before pairing.

The 86mm square faceplate fits standard UK single-gang or dual-gang back boxes with a minimum depth of 35mm. The square edge design has visible screw fixings at top and bottom, and the white finish coordinates with standard white electrical accessories across residential and light commercial settings. The dimmer is rated IP20 for indoor dry locations only and carries certification to EN 60669-2-1.

Frequently Asked

What's the difference between leading edge and trailing edge dimming?

Leading edge dimmers are designed for resistive loads like incandescent and halogen bulbs, and some dimmable LEDs. Trailing edge dimmers are typically better for capacitive loads like low-voltage transformers and most modern LED drivers. Check with your LED bulb manufacturer to confirm which dimmer type is compatible before installation.

Can this control LED bulbs?

Yes, the dimmer supports 3-100W LED loads per gang. However, not all dimmable LEDs are compatible with leading edge dimmers — compatibility varies by bulb brand and driver design. Test with a single bulb before completing the installation, or contact the bulb manufacturer for confirmation.

What does 2-gang 2-way mean?

2-gang means the plate controls two separate lighting circuits, each with its own rotary dimmer control. 2-way means each circuit can be dimmed from two different switch locations, such as at either end of a hallway or at the top and bottom of a staircase.

What back box depth is required?

A minimum 35mm back box depth is needed to accommodate the dimmer module safely. Standard UK single-gang or dual-gang back boxes at 35mm or 47mm depth will work.
