Performance & Light Output

This large-housing area light provides massive scalable illumination from approximately 22,970 to 42,770 lumens depending on the selected wattage and color temperature, easily replacing traditional 1000W HID luminaires while achieving an efficacy of up to 147 lumens per watt. The revolutionary OpticSwap system allows installers to change the light distribution pattern (Type III, Type IV, or Type V) using an under-door frame and latch design for quick, tool-free lens changes. The high-performance LEDs deliver a color rendering index (CRI) greater than 80 and maintain a highly prolonged L70 rated life of over 100,000 hours. The fixture features a True U0 design for dark-sky-friendly performance that eliminates undesirable sky glow.

Electrical & Controls

This fixture operates on a universal 120–277V AC driver with standard 0–10V dimming functionality to seamlessly integrate with facility energy management systems. The robust electrical components maintain a power factor greater than 0.95 and total harmonic distortion (THD) below 20%. It is comprehensively controls-ready, featuring an integrated NEMA/ANSI C136.10 7-pin twist-lock receptacle that comes standard with a 3-pin photocell and shorting cap for instant dusk-to-dawn capabilities. The receptacle also accepts compatible optional networked smart controls or standalone sensors (sold separately) for advanced site management.

Construction & Durability

Engineered to withstand harsh outdoor environments, the luminaire features a heavy-duty, die-cast aluminum Series 2 large housing with massive heat sinking, finished in a durable white powder coat. Its low-profile design improves application site aesthetics while minimizing wind load on tall poles. The fixture carries an IP65 rating to completely protect internal components from dust and water ingress in wet locations, operating reliably in extreme ambient temperatures ranging from -40°C (-40°F) up to 50°C (122°F).

Installation & Mounting

The luminaire streamlines site installations by including a pre-installed slipfitter mount directly in the box, designed to slide securely over standard 2-3/8-inch pole tenons. This adjustable slipfitter allows contractors to easily dial in the exact aiming angle required for the site, which is especially useful on tall poles. For unique application requirements, the fixture can also be adapted using compatible optional adjustable pole mounts or wall mount brackets (sold separately).
