SL SERIES
LED STAIRWELL FIXTURE Save up to *80% energy savings compared to traditional fixtures
INNOVATIVE TECHNOLOGY WITH STATE-OF-THE-ART PERFORMANCE SL Series LED Stairwell is specifically designed for use in stairwells where the space is often unoccupied for long periods of time. The fixture reaches full power only when the stairwell is occupied, otherwise resides at a power-saving dim light level. SL Series LED Stairwell has a built-in occupancy sensor and a intelligent wireless RF system that links multiple fixtures, providing light both above and below the occupied location.
*80% Energy Savings
Fixtures function equally well in hallways, restrooms, laundry facilities or any area that is often unoccupied.

When the stairwell is unoccupied, fixtures run at a low pre-set level of 6 watts input power. 7½’ mounting height, provides an average of 2 ft candles illumination on the stairwell landings. As soon as occupancy is sensed by any of the fixtures, an RF signal is transmitted to the fixtures on the floors immediately above and below the floor on which the motion is sensed. These fixtures then all switch to full input power mode of 22 watts and provide an average of 10 ft candles illumination on the stairwell landings. This same sequence takes place for occupants on multiple levels and thus assures that occupants will never be walking towards dark spaces. As occupants walks up or down the stairwell, the sensors detect their motion and automatically send RF signals to the fixtures in each occupants’ direction of travel, causing those fixtures to illuminate at full power. Once there are no longer occupants in the stairwell, the fixtures return to low power after a specified amount of time, which is configurable on-site from 1-30 minutes.
