Nothing's more depressing than a windowless room. And the thought that those who need sunlight the most (children, hospital patients, trauma victims) may habitually be deprived of it is profoundly unsettling.

Lightglass doesn't claim to replace the sun, but they do make a pretty persuasive case for how to brighten up windowless spaces—both from an emotional and physiological perspective.

It's a simple concept with an on-target execution. The modules are beautiful architectural elements made of aluminum and glass. The integrated LED illumination ranges from 2200-6500 K, simulating the fluctuations in light during a typical cloud-free day, "changing in color and intensity throughout the day, just like sunlight through a real window."
With an increasing amount of research showing that circadian rhythm is crucial to health, Lightglass' duplication of these subtle changes in the intensity of light can brighten spirits and improve energy, two factors that enhance productivity in a school or office setting, as well as speed healing in healthcare venues.
