Square Wall Stairway ID

SQW4 STW | IndirectDirect | Aluminum | 3 .5” | LED

The ADA-compliant Square Wall Stairway I/D luminaire is specifically designed for stairway applications. Pre-installed in the luminaire is an embedded nLight® occupancy detection sensor that is pre-programmed to remain at either 10% or 50% illumination when the stairway is unoccupied and brighten to 100% illumination once occupancy is detected.

Square Wall Stairway I/D can be specified with digital lumen management to deliver constant lumen output, extend LED longevity and save roughly 10% in energy use over Square's lifetime.

Square luminaires feature glare-free, Softshine® comfort optics and eldoLED® drivers that provide smooth, flicker-free digital dimming.
