XAL Recover Hospital Room

An interesting healthcare lighting product called “Recover” from Austrian firm XAL addressing circadian rhythm control for hospital rooms.  A wall-mounted fixture for indirect ceiling lighting, Recover features a spectral tuning capability with pre-programmed playback that matches the different color phases of a typical daylight sequence.  It’s a simple but elegant concept.

What I don’t see in the literature, however, is exactly what selection of LEDs they use for the different color channels.  Which leads me to question:  Are they really controlling the ~455-460nm wavelengths (which is the wavelength controlling circadian rhythm) or is this just an RGBW or RGBA color mixing system (which would not properly vary blue-light control)?

Here is the PDF brochure for the product category: xalrecover2014deen
