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

Blackened Steel Triple Dimmer Switch – Hand-Finished Darkened Steel Triple Dimmer

A Blackened Steel Triple Dimmer Switch is designed for spaces where lighting needs flexibility, but the finish still needs to feel distinctive and design-led. With control over three separate lighting circuits from one plate, it helps simplify the wall while giving the room a stronger sense of intent. Hand-finished in-house, the darkened steel surface brings timeworn character and an industrial heritage feel, creating a fitting that feels established, grounded and full of depth.

The feeling
This is lighting control with presence. The triple dimmer format keeps the wall cleaner and more resolved, while the Blackened Steel finish introduces a darker, richer kind of contrast than standard black. It feels architectural and grounded, with an aged quality that gives the room more character and makes the detail feel as though it belongs there.

Where it works best
Ideal for larger rooms where multiple layers of lighting need their own control. Think kitchen diners with pendants and wall lights, living rooms with feature and ambient lighting, or bedrooms where practical brightness needs to shift into a softer evening mood. A triple dimmer gives you independent control over each lighting element while keeping the wall finish more cohesive and visually calm.

Why it works
When several light sources need managing, separate switches can quickly make a wall feel overworked. A triple dimmer keeps everything together on one plate, giving you the flexibility to control each circuit independently while maintaining a cleaner, more considered look. In Blackened Steel, that practical function gains extra depth, helping the switch become part of the room’s wider material story rather than just a necessity on the wall.

The design detail
The Blackened Steel finish is hand-finished in-house, creating a darkened steel surface with real depth and timeworn character. It has an industrial heritage feel that’s richer and more nuanced than flat black, with an aged, established look that feels architectural and grounded. Combined with the clean proportions of the plate and matching dimmer knobs, it turns an everyday fitting into a detail that feels deliberate, substantial and full of atmosphere.

How to style it
Pair it with matching Blackened Steel switches and sockets for a cohesive look across the room, especially in interiors where darker finishes help anchor the overall scheme. It works beautifully with natural stone, aged timber, concrete, limewash walls, deep paint tones and layered neutrals, where the finish can add depth and structure without feeling overly stark. If you want the room to feel settled, characterful and architecturally resolved, Blackened Steel brings a darker finish with real substance.
