Electrical & Controls

Each fixture is equipped with a universal driver supporting either 120-277V or 277-480V input, ensuring compatibility with standard commercial and high-voltage industrial power systems. Standard 0-10V dimming allows seamless integration with occupancy sensors and automated facility controls.

Construction & Durability

The round housing is constructed from rugged, copper-free aluminum to resist corrosion in caustic chemical environments. The impact-resistant lens protects internal components from vibration stress common in heavy industrial settings. The complete luminaire is IP66 and NEMA 4X rated, with an operating temperature range of -40°C to 55°C. The 80W model measures 13.3″ L × 13.3″ W × 6.81″ H; the 150W and 200W models measure 14.6″ L × 14.6″ W × 7.4″ H.

Compliance & Certifications

This series is certified for hazardous locations including Class I, Division 2, Groups A–D (flammable gases/vapors) and Class II, Division 1 & 2, Groups E–G (combustible dusts), as well as Class III (ignitable fibers). IP66 rated. UL listed. DLC listed for utility rebate eligibility.

Installation & Mounting

Each fixture includes a factory-installed 25-degree stanchion mount for secure, fixed-angle positioning. The mount attaches directly to standard industrial conduit, providing a rigid installation that mitigates vibration in demanding operational zones.
