LEP luminaires scale to high lumen output needed for high mast lighting without sacrificing efficiency and lifetime as LED and HID sources do. LEP saves up to 75% energy while producing equivalent visibility. Long Life: LEP sources last 3-5 times longer than HPS sources, reducing costly maintenance at poles as high as 100ft in the air. LEP luminaires provide tremendous maintenance savings as well as mission-critical reliability for ports, airports, and industrial yards. Light Quality: The full color spectrum provides a greater than 2x advantage over HPS in nighttime visibility.
