The DS Series Luminaire is designed as a direct upgrade replacement for traditional dusk -to-dawn security light units. The Luminaire offers easy mounting. The rugged, corrosion -resistant, die-cast aluminum housing is outfitted with stainless steel hardware and an epoxy coating that offers an extremely long service life and excellent weather resistance. The DS offers multiple light distribution options to improve the visual experience for your specific application. While not commonly available on traditional HID or competing LED products, the DS offers a full line of roadway distribution patterns.
