Performance & Light Output

At 320W, the fixture delivers up to 51,000 lm (169 lm/W max efficacy). Output scales proportionally at 295W and 255W settings. CRI is 80 across all configurations. Rated functional life is 50,000 hours.

Smart & Control Features

The 65-1173 features an integrated low-voltage 3.5mm auxiliary control receptacle supporting modular sensing and automated facility lighting control:

• 0–10V Continuous Dimming (Standard): Standard dimming control compatible with commercial 0–10V dimmers.
• Sensor Compatibility (Accessory): Accepts field-installable sensors directly into the integrated waterproof port.

Compatible plug-and-play sensors include the Satco 12-Meter PIR Sensor (catalog # 86-238) and 15-Meter Microwave Sensor (catalog # 86-239) — sold separately. Field sensor adjustments must be managed using the required handheld programming remote (catalog # 86-237, sold separately).

Electrical

Powered by a constant current driver operating on 120-347V AC at 50/60Hz. Delivers high electrical efficiency with a Power Factor >0.9 and Total Harmonic Distortion (THD) <20%. Integrated 6kV surge protection protects internal electronics against transient voltage spikes. Includes pre-wired 0–10V dimming leads. RoHS compliant.

Construction

Housing & Thermal: Die-cast aluminum housing engineered to function as a high-efficiency passive heatsink, dissipating heat away from LED arrays and internal driver circuits to preserve lumen maintenance across the 50,000-hour rated lifespan.

Lens & Optics: Equipped with an IK10 impact-resistant polycarbonate (PC) lens delivering a 90° beam angle.

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

Environmental Sealing: IP69K rated and UL Listed for wet locations, providing a robust barrier resistant to high-pressure thermal washdowns and moisture ingress. Ambient operating temperature range: −40°F (−40°C) to 131°F (55°C).

Dimensions & Weight: 24.21" L × 14.76" W × 2.44" H. Fixture weight: 15.60 lbs.

Installation & Mounting

Standard Hardware: Ships standard with a 41" suspension kit for quick overhead installation.

Mounting Options: Direct surface or rigid mounting supported via a dedicated yoke mount bracket kit, sold separately.
