Smart & Control Features

The H17B supports two factory-configured control options:

• 0-10V Dimming (standard): Dims to 10% via standard 0-10V DC circuit, Dim to Off capable. Compatible with most commercial building control and energy management systems.
• Lightcloud Blue (accessory): Add PIR40B/LCB or MVS50B/LCB sensor/controller accessories for wireless Bluetooth mesh group control without additional wiring. Low-ceiling sensor options PIR20B/LCB and MVS20B/LCB also available.

Remote control accessory (catalog# MSR1) available for field adjustment of wattage and CCT. Occupancy sensors available in high-ceiling (PIR40B · MVS50B) and low-ceiling (PIR20B · MVS20B) Black finish variants, each with standard or Lightcloud Blue (/LCB) options.
