Product Specications
CREE SMARTCAST™ TECHNOLOGY
Cree SmartCast™ Technology changes the paradigm of lighting control. With the
press of a single button, Cree SmartCast™ Technology enabled luminaires and
controls create their own secure network and auto-associate to form logical groups
throughout every space. Integrated sensors and robust wireless communication
included in every luminaire combined with revolutionary OneButton™ Setup enables
automated setup and conguration of luminaires and wall controls. With no extra
wires or interfaces, Cree SmartCast™ Technology products reduce installation time
and complexity.
CREE TRUEWHITE® TECHNOLOGY
A revolutionary way to generate high-quality white light, Cree TrueWhite® Technology
is a patented approach that delivers an exclusive combination of 90+ CRI, beautiful
light characteristics, and lifelong color consistency, all while maintaining high luminous
efcacy – a true no compromise solution.
