Rated life 100,000 hours L70. Note: per-wattage × CCT lumen breakdown is not published in the RAB H17XXLB specification sheet; the figures above represent the full range across all configurations. Contact RAB Lighting for full photometric data by wattage and CCT setting.

Smart & Control Features

The H17XXLB supports two factory-configured control options and is compatible with the full RAB Lightcloud Blue wireless mesh sensor ecosystem:

• 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 variants PIR20B/LCB and MVS20B/LCB also available.

Remote control accessory (catalog# MSR1) available for field adjustment of wattage and CCT without ladder access. Occupancy sensors available in high-ceiling (PIR40B · MVS50B) and low-ceiling (PIR20B · MVS20B) variants.
