LED’s offer several inherent advantages for Outdoor Illumination due to their size, longevity, and energy saving potential. Within a system, LED’s can surpass many of the shortcomings of HID-based systems in uniformity, glare control, and full-spectrum light output. Specialized optics that “vector” the LED’s raw light output, careful control of the LED operating temperature, and a mechanical enclosure that will protect the LED’s over their lifetime are all part of the new Optical Modules from U.S. Architectural Lighting.
