Which dimmer do you need?

Choose the dimmer type that matches the bulbs on your circuit:

  • Standard dimmer: For traditional tungsten bulbs with a total load between 60W and 400W
  • LED dimmer: For LED bulbs or lower-load circuits with a total load between 5W and 150W
  • To work out the total load, simply add together the wattage of all bulbs connected to the circuit
  • Not suitable for low voltage lighting 12V/24V DC e.g. under cabinet strips
  • Smart bulbs should be kept on a standard on/off light switch and controlled via an app

Black Triple Dimmer Switch – Matt Black Triple Dimmer

A Black Triple Dimmer Switch is the kind of detail that makes a lighting scheme feel sharper, calmer and more intentional. Designed to control three separate lighting circuits from one plate, it helps larger rooms work harder without making the wall feel overcomplicated. The matt black finish brings crisp contrast and strong visual definition, giving practical lighting control a more architectural edge.

The feeling
This is lighting control with confidence. In black, the overall effect feels grounded and deliberate, adding structure to the wall while keeping the room visually uncluttered. It brings a clean, contemporary edge to the space, but still feels warm enough to sit comfortably within layered, lived-in interiors.

Where it works best
Ideal for larger rooms where different types of lighting need to work together. Think open-plan kitchen diners, living rooms, bedrooms with multiple lighting zones, or spaces with pendants, wall lights and secondary lighting all in play. A triple dimmer gives you independent control over each element while keeping the overall finish more streamlined.

Why it works
When several lights need separate control, too many switches can make a wall feel busy. A triple dimmer keeps everything together on one plate, so the scheme feels cleaner and more resolved. It gives you the flexibility to shape the mood of the room throughout the day, while the black finish adds clarity and contrast that helps anchor the wider design.

The design detail
The matt black finish gives this switch its bold architectural character. It creates crisp contrast against lighter walls and a more integrated, tonal look against darker schemes, making it a versatile choice across a wide range of interiors. With its clean lines and matching dimmer knobs, it feels quietly dramatic rather than harsh — a functional fitting that still earns its place visually.

How to style it
Pair it with matching black switches and sockets for a cohesive, well-resolved look, especially in spaces where contrast and definition are part of the design direction. It works beautifully with warm whites, plaster tones, natural wood, concrete, stone and deeper paint colours, where the matt finish can either sharpen the palette or blend into moodier schemes. Use it to echo black-framed glazing, darker hardware or architectural lighting for a room that feels joined up and intentional.
