This is the SkyVista: an artificial skylight that brings realistic skyscapes into your home. It has a fairly lightweight design, so you can install these the same way you would a flat panel light. SkyVista units have white, warm, and evening clouds.
The light coming out of these units conforms very closely to natural daylight. Both models (Nimbus 6.6 and Nimbus 12.3) can be ordered on Indiegogo).
