Note: per-CCT lumen breakdown by wattage is not published in the RAB H15B/480 specification sheet; contact RAB Lighting for full photometric data.

Smart & Control Features

The H15B/480 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 (confirm 480V compatibility with RAB Lighting).

Certifications & Rebates

UL Listed for wet locations. DLC Premium listed — product code S-N13W3S. To verify rebate eligibility with your utility provider, visit designlights.org and search product code S-N13W3S. RoHS compliant. IES LM-79 and LM-80 tested per IESNA standards.

Typical Applications

• Large warehouses and distribution centers on 480V service — eliminates step-down transformer cost and complexity for facilities already wired at 480V
• Heavy manufacturing and industrial facilities — black finish preferred for dark ceiling aesthetics; 480V input aligns with standard industrial panel configurations
• Cold storage and freezer warehouses — rated to -40°F (-40°C) for dependable cold-start performance at industrial voltages
• Covered loading docks and car washes — UL wet location listing and IP65 rating handle direct moisture exposure
• Maintenance and operations facilities — selectable wattage right-sizes output to task area without rewiring
