Dimmer Switch Buying Guide

How does a dimmer switch work?

A dimmer switch adjusts the power supplied to a compatible light fitting, allowing you to increase or reduce brightness to suit different tasks and moods.

Will a dimmer switch work with LED bulbs?

Yes, but the LED bulb must be marked as dimmable and compatible with the dimmer. Always check the dimmer's minimum and maximum load range and the requirements of your lighting before installation.

What does the gang number mean?

The gang number indicates how many individual dimmers are fitted to one faceplate. A 3-gang dimmer switch, for example, can control three separate lighting circuits from a single plate.

What is a rotary dimmer switch?

A rotary dimmer switch uses a knob that turns to adjust the brightness. Rotary controls offer precise adjustment and are a popular choice for traditional and contemporary interiors.

How many gangs do I need?

Choose the gang configuration according to the number of lighting circuits you want to control from the same position. A 1-gang dimmer controls one circuit, while 2, 3 and 4-gang versions control multiple circuits.

Which dimmer switch finish should I choose?

Choose a finish that coordinates with your other electrical accessories and interior hardware. Brass and antique finishes complement traditional interiors, while matt black, chrome and stainless finishes suit modern schemes.

Can I install a dimmer switch myself?

Electrical installation should be carried out by a qualified electrician in accordance with applicable UK wiring regulations, including BS 7671. Check the dimmer specification and LED compatibility before installation.
