Performance & Light Output

The luminaire produces 20,000 lumens at a crisp 5000K daylight color temperature, achieving an excellent efficacy of 133 lumens per watt. The integrated Type III optics generate an asymmetrical forward-throw light pattern that directs the majority of the light forward and equally on both sides, which is ideal for extending pole spacing along streets and perimeters. The LED light engine delivers a color rendering index (CRI) of 70 and maintains a rated lifespan of 50,000 hours based on TM-21 calculations.

Electrical & Controls

This roadway light operates on an electronic universal 120–277V AC driver with standard 1–10V dimming capabilities. The electrical components maintain a power factor greater than 0.90 and total harmonic distortion (THD) below 20%, securely protected by built-in 10kA surge suppression. It comes factory-equipped with an integrated photocell to enable automated dusk-to-dawn lighting without the need for additional networked controls.

Construction & Durability

Engineered for harsh outdoor environments, the fixture features a heavy-duty cast aluminum housing finished in a durable silver gray powder coat. The LED drivers mount directly to the die-cast back housing to provide optimal heat sinking and prolonged component life. The luminaire is 3G vibration rated to ensure structural integrity against wind and traffic vibrations on tall poles, and the housing is completely sealed against moisture and environmental contaminants, carrying a UL Wet Location listing and an operating temperature range of -40°C to 40°C (-40°F to 104°F).

Installation & Mounting

Designed for standard roadway and area lighting applications, the 150W fixture features an aerodynamic profile with an EPA of 0.4711 to minimize wind load. The housing includes a convenient removable door for easy access to the electrical compartment during wiring and maintenance. It mounts natively to standard horizontal mast arms for straightforward pole installations.
