Performance & Light Output
This LED dusk-to-dawn light produces 6,200 lumens at a crisp 5000K daylight color temperature, achieving an excellent efficacy of 138 lumens per watt. It utilizes breakthrough LEDs and precision-engineered optics to provide uniform and exceptional illumination that effectively replaces up to 250W traditional metal halide area lights. The high-performance LED light engine delivers a color rendering index (CRI) of 70 or greater and maintains a highly reliable estimated lifespan of over 50,000 hours, significantly reducing maintenance needs.
Electrical & Controls
The luminaire operates on a universal 120–277V AC driver designed for stable commercial use. The electrical system maintains a power factor of 0.90 or greater and total harmonic distortion (THD) below 20%. For maximum energy savings and site security, the fixture comes standard with an included 120-277V photocell that automatically turns the light on at dusk and off at dawn, eliminating the need for manual switches or external timers.
Construction & Durability
Engineered for harsh outdoor environments, the fixture features a durable die-cast aluminum housing finished in a standard dark bronze polyester powder-coat. The traditional dusk-to-dawn design has been modernized with softened edges for a versatile look that complements many applications. The housing is UL and cUL listed for wet locations, guaranteeing reliable operation in extreme ambient temperatures ranging from -40°C (-40°F) up to 40°C (104°F).
Installation & Mounting
The SDD series area light is designed for highly adaptable and straightforward site installation. The fixture can be mounted directly to a flat wall surface straight out of the box for perimeter security applications. For extended reach and traditional pole-mounted street or yard lighting configurations, the luminaire is fully compatible with an optional pole mounting arm kit (sold separately).
