A dimmer switch allows you to adjust the brightness of a light to the exact level you want. You can dim the light for a cosy atmosphere or switch it up to full brightness when you are cleaning for instance. We sell dimmer switches from Nexa, BG and Cotech. The type of dimmer switch you need depends on the type of light it is to be used with. Incandescent bulbs and halogen bulbs work with all types of dimmer, but to dim LED lights you need an LED dimmer capable of controlling the electronics built into the LED light. For modern homes we have smart, wireless dimmer switches. We also have more traditional manual rotation dimmer switches, both single and double. Bear in mind that the installation of a dimmer switch must only be carried out by a competent, registered electrical installer. This applies even if you are replacing an existing light switch with a dimmer.
