Advanced Lighting for a Better Life

Lighting Solutions That Adjust to Your Lifestyle Throughout the Day

Achieving the perfect lighting in your home every time requires more than basic dimming capabilities. How can you move beyond the traditional flat dimming of lights in your Seattle area home? Tunable lights provide “warm dimming” by adjusting color temperature as they transition from cool blue colors to warm amber colors.

Though lower-end tunable lighting solutions are available through DIY installations, Ketra lighting systems from Lutron offer the ultimate efficiency and elegance – whether you live in Bellevue, Seattle, Mercer Island or beyond. Only Ketra circadian lighting delivers automated indoor natural lighting throughout the day, intuitive control through Lutron HomeWorks QS integration, and elegant fixture varieties. Obot Electric and Wipliance harmonize to provide a seamless, turnkey solution for design, installation and customization of your KETRA system.

Each evening it's easier to wind down with warm, amber hues that promote relaxation and sleep. Set your preferences based on your bedtime routine or run with Ketra's automated lighting settings.

Excellence Delivered Every Time


Why should you go with Ketra lighting fixtures instead of other lower-end tunable lighting solutions? Although many bulbs promote circadian lighting, none deliver the precision and optics of Ketra fixtures. Ketra offers full spectrum tunable lighting by combining white LED with red, green, and blue light. Though most tunable lighting solutions have device and design limits, Ketra lighting systems offer unprecedented variety in both bulb designs and integration possibilities.

Embrace the Ketra Difference
  • Expand to pendant, linear, and luminaire fixture models.
  • Tunable lighting extends from 1,400K to 10,000K.
  • Tightly packed LED design delivers uniform color optics.
