While the recommended ambient light level for restrooms is low, lighting the walls and
putting some brightness on the ceiling will increase the perceived brightness of the
space. Increased light levels are appropriate at the sink or counter near the mirrors.
Occupancy sensors should control the lighting in restrooms where luminaires are
frequently left on for an extended period of time. Ceiling mounted, ultrasonic sensors
recognize occupants even in a space with high partitions. Locate and aim the sensor to
switch on when the door opens and then turn off after a pre-determined amount of time.
