Circadian Lighting Design in Los Angeles
GWI received CEDIA’s Best Lighting Solution award for our circadian lighting work in Los Angeles. We design Lutron Ketra systems that actively support sleep quality, daytime focus, and energy levels — because light is biology, not just aesthetics.
🧬 The Science
Dr. Satchin Panda’s research at the Salk Institute established that light is the primary regulator of the human circadian clock. Morning blue-enriched light activates the system. Evening warm light prepares the body for sleep. GWI programs Ketra systems around this science.
💡 Lutron Ketra Technology
Five independent light sources per fixture — red, green, blue, warm white, and cool white — enabling true spectral accuracy at every color temperature. The only residential fixture that can genuinely replicate natural daylight progression.
🎬 Scene Design
Every scene is designed for how the client actually lives — morning activation, work focus, family dinner, movie mode, sleep preparation. Programming that feels intuitive because it’s built around biology.
What is circadian lighting and does GWI install it?
Circadian lighting uses tunable spectrum technology to support the body’s natural biological clock — providing morning blue-enriched light for energy and evening warm light for sleep preparation. GWI installs Lutron Ketra circadian lighting in Los Angeles luxury residences and received CEDIA’s Best Lighting Solution award for this work.
