In the summer of 2010 the California Lighting Technology Center (CLTC) and Philips Hadco produced an adaptive solution that combined a dimmable LED source and a mounting collar equipped with occupancy sensors. The collar provides 360-degree occupancy sensor coverage. This demonstration involved whole-head replacement of the existing luminaires, but results could also be achieved with a retrofit kit. The new luminaires feature good color quality, improved efficiency and a longer lifespan. Adaptive controls enable the luminaires to reduce power to 50% during vacant periods and increase to 100% light output when occupants approach. Switching between the two light levels maintains adequate light for security and wayfinding while maximizing energy savings. 

Features & Benefits:
  • Adaptive light output based on occupancy
  • Long life source (60,000 hours) reduces operating and maintenance costs
  • CCT: 5000K; CRI: 70
  • Easy to install and retrofit
  • Compatible with a wide range of architectural shells
