Performance & Light Output

Engineered to replace traditional 3-lamp F32T8 fluorescent fixtures, this unit produces between 4,080 and 6,800 lumens with a high efficacy of up to 142 lm/W. The luminaire features an 80 CRI rating for accurate color rendering and utilizes a diffuse polycarbonate lens to minimize glare. High-quality surface-mount LEDs maintain consistent luminous output with an L70 lifespan of 100,000 hours, ensuring long-term operational reliability.

Electrical & Controls

Operating on a standard 120-277V universal driver, the fixture supports 0-10V continuous dimming for integration with energy management strategies. The electrical architecture includes 2.5 kV built-in surge protection and maintains a high power factor of up to 99.9% at 120V. During grid interruptions, the integrated battery backup immediately engages to supply 90 minutes of emergency power. This unit is also compatible with optional passive infrared (PIR) and microwave (MVS) occupancy sensors (sold separately) for enhanced automated control.

Construction & Durability

Built for severe conditions, the housing is constructed from impact-resistant IK08 polycarbonate sealed with high-temperature silicone gaskets. The fixture achieves stringent IP66 and NEMA 4X ratings, guaranteeing defense against windblown dust, high-pressure hose-directed water, and corrosive elements. It is UL listed for wet locations, NSF certified for sanitation, and holds a UL94 5VA flame rating, operating securely in ambient temperatures up to 104°F (40°C).

Installation & Mounting

The washdown fixture is designed for adaptable deployment across complex industrial infrastructure. It ships standard with quick-mount stainless steel snap-on brackets for rapid surface mounting to ceilings or walls. For suspended applications, V-Hook brackets are also supplied, alongside tether cables that ensure stability and ease of wiring during the installation process.
