The ability to produce light without heat, plus an exceptionally long life make the green-technology LED Lumiglas luminaires ideal for heat-sensitive processes and use in applications where exceptional reliability and long operating life are required. Two versions of the Lumiglas UL35-LED lights are currently available—a small housing using three high-capacity diodes rated at 121 foot-candles or a slightly larger housing using six high-capacity diodes that produces 242 foot-candles illumination. Both provide service well beyond that of conventional filament light sources in the same compact package.
