E-Lite Smart series LED high mast lights are designed to provide the best combination of horizontal and vertical illumination for expressway, freeway interchanges, industrial sites, docks, sports facilities, airports and other large area applications. The 450W high mast light produces 43,296 lumens of high intensity light while drawing significantly less power and achieve up to 70% reduction in energy cost compared with incumbent high intensity discharge systems. The high mast light incorporates 5 sealed LED light engines each consisting of 216 high brightness Cree XT-E LEDs. The precision control TIR type optics are designed to optimize application efficiency, improve uniformity and minimize glare. The high mast light features a highly efficient thermal management system that provides thermal path junction through the aluminum heat sink for excellent thermal transfer. The high power factor and low THD LED electronic driver is equipped with over-voltage, under voltage, short-circuit and over temperature protection circuit. The rugged, die-cast aluminum housings are IP65 rated and polyester powder coated to withstand extended outdoor exposure for exceptional durability and long term reliability. Optional integrated sensors offer enhanced control options for lighting management and increased energy savings.
