The Athena Series (XASW02) LED Wall Mounted Stairwell fixture is specifically designed for use in stairwells where the space is often unoccupied for long periods of time. It reduces energy usage by up to 80 percent by automatically providing fully ON light levels only when the space is occupied and returns to power saving dim levels when the space is unoccupied. These fixtures function equally well in hallways, bathrooms, laundry rooms, or any area that is frequently unoccupied.
