The product description provided by the supplier is:

Prizm® Aircraft Cabin Lighting is premium, fully configurable white lighting with full color capability. Prizm allows you to program the perfect white lighting for your cabin design: bright, cool white for a sophisticated, modern style; soft, warm white for a comfortable, cozy feel; or anything in-between. In addition, Prizm can be easily adapted to the phase of the flight to enhance passenger comfort, increase productivity, and reduce jet lag.  That’s not all, Prizm also provides the option for full spectrum color lighting so you can set unlimited custom practical moods. All of this controlled by existing cabin lighting controls or any carry on device via the mobile app.
 
Available for upwash, downwash, lower accent, galley, lavatory, and cup holders, Prizm® Aircraft Cabin Lighting can be installed in your airplane at a price that is competitive with basic white-only lighting options.
