Xeleum Lighting today announced the introduction of its new Athena Series Stairwell LED Light Fixture. Specifically designed for use in stairwells that may be unoccupied for long periods of time, it automatically provides 100% light levels only when the space is occupied and dims to a power saving level of approximately 20% when the space is unoccupied. The combined use of occupancy sensors and LED lighting makes possible dramatic reductions in energy consumption, with savings of up to 85% over conventional stairwell fixtures that do not employ these two features.
