Wet location emergency lights automatically switch on when power goes out and illuminate pathways toward exits in areas where the lights may be exposed to water. They may be rated for a specific degree of protection from water drips, splashes, or sprays. Emergency lights can stay lit for at least 90 minutes to guide evacuations and allow first responders and maintenance staff to find their way when working within buildings during an outage. Also known as egress or bug-eye lights, they run on batteries or have a battery backup to operate independently of hardwired fixtures. Emergency light units must be installed and regularly tested in accordance with local safety codes. Mounting them at the recommended spacing provides coverage to meet code-specific illumination levels along the path of egress and eliminate dark spots without overlighting.
