Performance & Light Output

This large-housing area light provides massive scalable illumination depending on the selected wattage and color temperature, engineered to efficiently replace traditional 1000W Metal Halide luminaires. The integrated Type III optics are precisely designed to shape the light distribution, maximizing efficiency and application spacing while minimizing undesirable backlight. The high-performance LED light engines deliver consistent, binned color and maintain a highly prolonged rated life of 100,000 hours based on TM-21 calculations. When properly mounted, the optical design can conform to dark sky requirements to eliminate upward sky glow.

Electrical & Controls

This fixture operates on a dedicated 347–480V AC driver with standard 0–10V dimming functionality (dimmable down to 10%) to seamlessly integrate with facility energy management systems. The robust electrical components maintain a power factor greater than 0.90 and total harmonic distortion (THD) below 20%, heavily fortified by 20kA surge protection to defend against severe industrial power anomalies. The luminaire is comprehensively controls-ready; it supports optional plug-and-play PIR or microwave occupancy sensors, Bluetooth controllers, and 3-pin or 7-pin NEMA twist-lock photocells (all sold separately) to maximize energy savings and security.

Construction & Durability

Engineered to withstand harsh outdoor environments, the luminaire features a rugged, one-piece die-cast aluminum housing finished in a corrosion-resistant dark bronze coating. The integrated heat sink hat optimizes thermal dissipation through advanced convection cooling management, actively extending the life of internal components. The fixture's low-profile design minimizes wind load, and it is 3G vibration rated to ensure structural integrity on tall poles. The optical and electrical compartments are completely sealed against moisture and environmental contaminants, carrying a UL Wet Location listing and an ambient operating temperature range of -40°C (-40°F) to 45°C (113°F).

Installation & Mounting

This fixture is designed for mounting heights ranging from 26 to 50 feet in area lighting applications. To accommodate diverse site requirements, the fixture requires a compatible modular mounting bracket (sold separately). Contractors can easily adapt the luminaire for the specific application by purchasing the appropriate cast aluminum slipfitter, standard versatile arm mount (for square/round poles), adjustable arm mount, wall mount, or yoke mount. Additional optional accessories like external glare shields and back light control shields are also available separately to further customize site illumination.
