Smart Lighting description

The Smart Lighting Director adds closed-loop sensing, providing tuning directives to an existing smart light architecture. Sensor-hub expansion capabilities include native support for various ams environmental sensors for added IoT flexibility. Non-networked versions support stand-alone color/lumen maintenance and daylighting functions for new designs and retrofits.
