• Sensor Compatibility (Accessory): Compatible with field-installable PIR and microwave occupancy sensors.
• Lightcloud Blue (Accessory): Compatible with Bluetooth mesh controllers for wireless group control, automated scheduling, and occupancy sensing.

Compatible plug-and-play sensors include the PIR40, PIR20, MVS50, and MVS20 series — sold separately.

Electrical

Powered by a Class 1 constant current driver operating on 120–277V AC at 50/60Hz. Integrated 6kV + 6kV surge protection protects internal electronics against line-to-line and line-to-ground transient voltage spikes. Includes pre-wired 0–10V dimming leads. Factory-equipped with a 6-foot cord. RoHS compliant.

Construction

Housing & Thermal: Precision die-cast aluminum housing. The housing functions as a high-efficiency passive heatsink, dissipating heat away from LED arrays and internal driver circuits to preserve lumen maintenance across the 100,000-hour rated lifespan.

Lens & Optics: Features a durable polycarbonate lens.

Finish: Commercial finish in White formulated for high resistance against corrosion and surface wear in demanding industrial facilities.

Environmental Sealing: IP65 rated and UL Listed for wet locations, providing a sealed barrier resistant to dust and moisture ingress. Ambient operating temperature range: −40°F (−40°C) to 122°F (50°C).

Dimensions & Weight: 12.19" Dia × 8.06" H (with hook). Fixture weight: 6.4 lbs.

Installation & Mounting

Standard Hardware: Ships standard with a 3/4"-14 NPT hanging hook accessory for quick suspension installation.

Mounting Options: Compatible with rigid pendant mounting via the PM KIT (sold separately) and direct surface mounting via the SM KIT (sold separately).

Wiring: Includes a factory-installed 6-foot cord for power input and 0–10V dimming leads.
