• Calibrated tristimulus XYZ CCT delivers closed loop CCT/daylighting directives to application microprocessor
  • I²C and serial UART interfaces with simple text or register-based commands to control and configure key light tuning supervisory functions
  • Calibrated-for life nano-optic silicon interference filters for XYZ, CCT, DUV and lux
  • Additional master I²C for add-on ambient light sensing
  • 20-pin LGA 4.5mm x 4.7mm x 2.5mm, -40°C to +85°C


  • Maximizes system flexibility and lowers overall manufactured costs while adding precision to tunable white luminaires and lamps
  • Easy integration with flexible interface options to support any standard application host microprocessor
  • Eliminates light-by-light factory calibration for most tunable white and daylighting luminaires
  • Built-in support for daylighting/daylight harvesting systems
  • Compact lighting-capable package with no added optics required
