Smart & Control Features

The H15XLB 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.

Remote control accessory (catalog# MSR1) available for field adjustment of wattage and CCT on 0-10V models. Occupancy sensors: PIR40B (PIR, max 12m, IP66) and MVS50B (microwave, max 15m, IP65) available with or without Lightcloud Blue integration. Order /LCBS suffix for factory-installed Lightcloud Blue sensor; /LCBS/E for Lightcloud Blue with emergency battery backup.
