Ketra fixtures deliver high-fidelity, naturalistic light that shifts in color temperature and intensity across the course of the day, mirroring the qualities of natural daylight. The technology behind Ketra supports human-centric lighting design and precise creative control for residential and commercial spaces.

For more on the effect of light on human health, see the TED talk by Mariana Figueiro, Director of the Lighting Research Center at Rensselaer Polytechnic Institute in Troy, NY.
