Smart & Control Features

The H15 supports two factory-configured control options:

• 0–10V Dimming (standard): Dims to 10% via standard 0–10V DC circuit. Compatible with most commercial building control and energy management systems.
• Lightcloud Blue (accessory): Add PIR40/LCB or MVS50/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: PIR40 (PIR, max 12m, IP66) and MVS50 (microwave, max 15m, IP65) available with or without Lightcloud Blue integration.
