Schedule a ConsultationKetra: Where Lighting Becomes Wellness Infrastructure
Lutron Ketra is not just another smart lighting system. It’s a biologically-tuned illumination platform that dynamically adjusts color temperature and intensity throughout the day to mirror natural light — supporting your circadian rhythm, alertness, and sleep quality. GWI is one of Los Angeles’ leading Ketra installers, deploying this technology in estates across Bel Air, Pacific Palisades, Beverly Hills, and Malibu where clients invest in their environments as seriously as their health.
16,000 Shades of White
Ketra fixtures produce any white from 1,400K warm amber to 10,000K cool blue-white — with 16 million color combinations. Morning light is energizing; evening light winds down naturally.
Natural Dimming Curve
Standard LED dimmers shift color as they dim — a yellow, flat quality that looks artificial. Ketra’s Natural Dim technology maintains accurate color rendering at any intensity, matching candlelight at low levels.
Circadian Programming
GWI programs Ketra scenes that track the sun’s arc — waking your home with energizing light at 6,500K, transitioning to warm 2,700K by 9 PM. Integrated with Lutron RadioRA 3 and Control4.
Designer-Grade Fixtures
Ketra’s A-series retrofit bulbs and dedicated fixtures work in standard housings. For new construction or remodels, GWI specifies Ketra-native recessed and surface fixtures from the Lutron/Ketra catalog.
A GWI Ketra Installation in Practice
A recent GWI project in Pacific Palisades deployed Ketra across 6 bedrooms, a primary suite, home gym, and open living areas. The system runs a programmed circadian arc during the week, shifts to entertaining scenes on weekends, and automatically dims when the homeowners’ Apple Watch detects sleep mode via HomeKit. The client’s sleep quality feedback six months in: measurably improved. This is the intersection of smart home technology and wellness that GWI was built to deliver.
