Lutron Lighting Controls
Lutron RadioRA 3 Installation | Lutron Certified Installers since 1998
Wireless smart lighting and automated shading for exceptional homes — professionally designed, installed and programmed by Custom Controls.
RadioRA 3 is Lutron’s mid-range wireless lighting and shading system, designed specifically for homeowners who want the elegance and reliability of Lutron without the complexity of a full Homeworks QSX installation. Launched in the UK in January 2025, it sits between the entry-level Caséta and the flagship Homeworks QSX — delivering professional-grade control, beautiful keypads and Lutron’s world-class reliability. Crucially, it is fully wireless. Using Lutron’s proprietary Clear Connect RF technology — which operates independently of your Wi-Fi — RadioRA 3 can be installed without touching a single wall. It is ideal for retrofits in period homes, renovations, and any project where rewiring is not desirable or practical.

Three components. One seamless experience.
RadioRA 3 unifies intelligent lighting, precise dimming controls and automated window treatments into a single, professionally programmed system.
Intelligent Lighting
Lumaris LED tape and tunable white sources deliver flicker-free dimming from 0.1% to 100%, and a full spectrum from warm 1,800K candlelight to crisp 4,000K daylight — all within the RadioRA 3 ecosystem with no third-party bridges.
Wireless Controls
The Vierti keypad brings a timelessly modern aesthetic to your walls. Pico wireless remotes, occupancy sensors and daylight sensors complete the picture — all powered by Clear Connect RF, not Wi-Fi, for bombproof reliability.
Automated Shading
Lutron is the world’s number one motorised shade supplier. RadioRA 3 integrates wirelessly with Palladiom battery-free shades, roller blinds, Roman blinds and more — giving you complete daylight control alongside your lighting scenes.
No Rewiring Required — Perfect for Existing Homes
RadioRA 3’s wireless architecture makes it the intelligent choice for any property where rewiring is impractical, unwanted or simply unnecessary.
- Period & listed properties — No chasing, channelling or disturbing original fabric. RadioRA 3 installs over your existing wiring.
- Retrofits & renovations — Add smart lighting to one room or an entire home, expanding the system over time as required.
- Clear Connect RF technology — Operates entirely independently of your home’s Wi-Fi network. No signal drop, no dropouts, no interference.

Scenes & Automation — One Button. Your Perfect Room.
We program custom scenes that transform your home at the touch of a button — blending lighting levels, colour temperature and shade positions into a single, effortless moment.
- Welcome Home — Hallway lights glow warm, blinds rise, the kettle corner lights gently on.
- Dinner — Dining room drops to 40%, kitchen worktop lights stay bright, shades close for privacy.
- Cinema — Living room fades to black, bias lighting activates, motorised blackout blinds descend.
- Goodnight — Every light in the property off, exterior lighting activates, shades closed, alarm set.
- Circadian scheduling — Lighting colour temperature shifts gradually through the day, supporting your natural rhythm.
