The Benefits of Natural Light
We’ve evolved into seeing natural light as a guide, and we work and respond to its conditions. However, the contrast of cool LEDs inside with warm sunlight hues outside creates a disconnect that affects our comfort and well-being. Eliminate this disconnect with Ketra’s circadian lighting technology, designed to promote better rest, relaxation, and focus.
How Ketra Mimics Natural Light
Ketra’s Natural Light solution tunes along the blackbody radiation curve of natural light through correlated shifts in color temperature and intensity. As the sun gradually shifts, schedule Ketra’s Natural Light to match the light outdoors throughout the day without you having to lift a finger.

The Color Rendering Index

The color rendering index is the primary way to gauge the quality of lighting fixtures and how well they will interact with specific colors.
What it is
CRI measures how well a light source can render colors in relation to a natural reference point like daylight.
How it's Measured
It is measured on a scale from 0 to 100, with higher numbers correlating with brighter, more accurate lighting.
Why it Matters
LED sources with a CRI of 90 or above boast excellent color rendering capacity, faithfully revealing the colors of your interiors and artwork.

The Power of Precision Optics

Using the power of reflection and refraction, precision optics allow designers and homeowners to deliver lighting exactly where they want it.
