Performance & Light Output

Engineered for high-efficiency illumination, this luminaire delivers up to 7,323 lumens with an impressive efficacy reaching 154.8 lm/W. The fixture utilizes a diffuse polycarbonate lens to minimize glare across wide operational areas while delivering accurate color representation with an 84-86 CRI. High-quality surface-mount LEDs ensure long-term luminous stability, providing an L70 lifespan rated for 100,000 hours of continuous operation.

Electrical & Controls

Operating on a universal 120-277V constant-current driver, the fixture supports standard 0-10V dimming protocols and includes built-in 2.5kV surge protection. It maintains a high power factor of 99.9% at 120V to ensure efficient electrical consumption. During grid interruptions, the factory-installed battery backup automatically engages to supply 90 minutes of emergency power. The fixture is also fully compatible with standard 0-10V controls and optional passive infrared (PIR) or microwave occupancy sensors (sold separately) for enhanced automated energy management.

Construction & Durability

Built to endure rigorous sanitation procedures and harsh environments, the housing is molded from IK09 impact-resistant polycarbonate and sealed with durable gaskets. The unit achieves strict IP66 and NEMA 4X classifications, completely repelling dust, hose-directed water, and corrosive agents. It holds a UL94 5VA flame classification, is NSF certified for public health environments, and operates safely in ambient temperatures up to 104°F (40°C).

Installation & Mounting

Designed for versatile deployment, this 4-foot luminaire features 1/2-inch openings for secure conduit and cord entry. It ships standard with stainless steel spring clips for rapid surface mounting to ceilings or walls. For complex industrial configurations, the unit is fully compatible with optional chain mounts, junction box adapters, angled surface mounts, or vandal-resistant brackets (sold separately).
