Composed of Multiple Light Sources
Tunable white light typically features “warm” or “cool” light sources limited between 2,700K and 3,000K. Ketra fixtures contain multiple primary light sources, which combine their unique spectrums of light for a greater color gamut that designers can dial in for any application or aesthetic.

Beyond Orange, White, and Blue

Tunable smart bulbs usually offer "warm" or "cool" tones, typically limited to a range of 2,700K to 3,000K. Ketra fixtures, however, feature multiple primary light sources that blend their distinct spectrums to create a broader color gamut. This allows designers and homeowners to fine-tune lighting for any application or aesthetic.

Why Natural Light Matters

We naturally respond to the rhythms of sunlight, using it as our guide as the day progresses. However, the stark contrast between cool indoor LEDs and the warm hues of natural sunlight can disrupt our comfort and well-being. Ketra’s lighting solutions bridge this gap, enhancing your focus, relaxation, and sleep.

How Ketra Recreates Sunlight

Ketra’s Natural Light technology mimics the natural light spectrum by adjusting along the blackbody radiation curve, seamlessly shifting color temperature and intensity hour by hour. As the sun moves, Ketra’s Natural Light can be scheduled to synchronize with outdoor light automatically.

CRI: The Color Rendering Index

The color rendering index (CRI) is the key metric for assessing the quality of lighting fixtures and their ability to accurately reproduce specific colors.

What It Is

CRI measures how accurately a light fixture renders colors compared to a natural reference point, such as daylight.

How It’s Measured

CRI is measured on a scale from 0 to 100. The higher the number, the brighter and more accurate your lighting is.
