Lutron lighting and shading, designed for the evening

The company that invented the dimmer, and still makes the best one. HomeWorks QSX and RadioRA 3 for lighting and blinds, with Ketra where the light itself has to change through the day.

01 The partnership

The dimming is the part you cannot fake.

Lutron hardware wired in is half a system. The other half is the design work: trim levels set per fitting, dimming curves matched to the load, scenes built around eight in the evening rather than noon.

  • Trim levels and dimming curves set per circuit, not left at default.
  • Access to the Palladiom, Alisse and Avienna keypad ranges and to Ketra.
  • Wired and wireless on one platform, planned rather than improvised.
  • Scenes commissioned in the room at the time of day they will be used.

Nobody has ever complimented us on a dimmer. They say the house feels calmer in the evening, which is the same observation from the other end.

03 The brand

Sixty-five years of getting light right.

Lutron was founded in 1961 by Joel Spira, who invented the solid-state dimmer in a spare room and then built a company around getting light to behave. The engineering culture has not really changed: the products are conservative, over-specified, and expected to be on the wall in twenty years.

The residential range now runs from Caseta at the domestic end through RadioRA 3 to HomeWorks QSX, which handles up to ten thousand zones, mixes wired and wireless on one platform, and unlocks Ketra full-spectrum fittings, Rania downlights and the metal keypad families.

04 The range

The families we specify.

The platform is chosen by the building stage and the fitting schedule, not by the budget alone.

FamilyWhat it isWhere we use it

Principal rooms
Ketra fittings
Full-spectrum tuneable downlights and linear. Specified where the lighting designer has asked for circadian behaviour.
Kitchens · Living · Studies
Rania downlights
Precision LED downlights for architectural lighting at the top end, where beam control matters as much as output.
Architect-led schemes
Sivoia QS shading

05 How we specify it

What it costs, roughly.

Lutron pricing is driven by scale, keypad choice and how deep the integration goes. Indicative UK ranges for 2026, supplied, programmed and commissioned.

Band 01

RA2 Select, a smaller house

Eight to twenty-five thousand pounds. A single floor or a modest house, standard keypads, sensible circuit count. A genuine step up from wall dimmers.

Band 02

RadioRA 3, a family house

Twenty-five to seventy thousand pounds. Twelve to twenty zones with engraved Sunnata keypads and wireless shading in a four-bedroom house.

Band 03

HomeWorks QSX, flagship

Eighty thousand upwards. Palladiom keypads, wired shading, Ketra fittings and a hundred-plus zones. Keypad finishes and fitting count move this a long way.

Indicative only. A design visit produces a fixed price.

08 Common questions

Lutron, honestly answered.

If the fitting schedule includes Ketra, or the house is large with wired shading and metal keypads, it is HomeWorks. If the house is finished and you want serious wireless control with minimal disruption, RadioRA 3 does a great deal for less.

In the rooms you spend mornings and evenings in, yes. It changes colour temperature and intensity through the day rather than just dimming, and people notice it without being able to say why. In a utility room, no.

Usually. We check each fitting and driver for dimming compatibility first, because a good system driving a poor LED driver still flickers. Where a fitting will not behave, we say so before you buy the system.

Quiet enough for a bedroom. Wired Sivoia QS motors are the quietest, battery Triathlon slightly less so. We would rather you heard one running before deciding.

They do not, but it is the difference between a keypad a guest uses and one they avoid. Engraving is cheap next to the rest of the system and we recommend it in every shared space.

Yes, and it often does. Lutron holds the lighting and shading layer, because a button press should feel immediate, and the wider platform handles everything else.
