Performance & Light Output

Rated life 100,000 hours (L70). Delivers direct energy reduction compared to traditional high-intensity discharge systems.

Electrical

Powered by a constant current driver operating on 277–480V AC at 50/60Hz. Delivers high electrical efficiency with a Power Factor >0.90 and Total Harmonic Distortion (THD) ≤20%. Integrated 6kV surge protection protects internal electronics against line-to-line and line-to-ground transient voltage spikes. Includes standard 0–10V dimming. RoHS compliant.

Construction

Housing & Thermal: Precision aluminum housing engineered with radial convection cooling fins. The lightweight, corrosion-resistant housing functions as a high-efficiency passive heatsink, dissipating heat away from LED arrays to preserve lumen maintenance across the rated lifespan in high ambient temperature environments.

Lens & Optics: Features an ultra-durable glass lens built for high-temperature conditions and enduring optical clarity.

Finish: Commercial finish in Black.

Environmental Sealing: IP65 and NEMA 4X rated and UL Listed for wet locations, providing a sealed barrier resistant to dust, moisture, and corrosion. Ambient operating temperature range: −40°F (−40°C) to 176°F (80°C).

Dimensions & Weight: 18.90" Dia × 12.06" H. Fixture weight: 17.2 lbs.
