Performance & Light Output

This large-housing area light provides massive scalable illumination from approximately 27,030 to 40,650 lumens depending on the selected wattage and color temperature, easily replacing traditional high-wattage HID luminaires while achieving an efficacy of up to 149 lumens per watt. The revolutionary OpticSwap system allows installers to change the light distribution pattern using an under-door frame and latch design for quick, tool-free lens changes. The fixture comes with a Type III lens installed and a Type V lens included in the box, while Type II and Type IV lenses are available separately. The high-performance LEDs 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 dedicated 277–480V 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%, protected by built-in 6kV surge protection. It is comprehensively controls-ready, featuring an integrated NEMA/ANSI C136.10 3-pin twist-lock receptacle equipped with a shorting cap. For automated dusk-to-dawn operation, this fixture is explicitly compatible with the optional Keystone 277-480V twist-lock photocell (KT-TLP-HV-3PN), sold separately.

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 bronze color. 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

This specific "NM" (No Mount) model is designed for maximum site flexibility, meaning mounting hardware is not included in the box. To complete the installation, the fixture requires a compatible Keystone accessory mount (sold separately). Contractors can choose from five contractor-friendly mounting options: a universal slipfitter, trunnion, adjustable pole mount, fixed pole mount, or wall adaptor.
