LED Exit & Emergency Lighting
Exit signs and emergency lighting for life-safety systems—egress fixtures specified by code requirements, mounting conditions, and backup duration.
LED exit and emergency lighting supports code-compliant egress visibility during loss of normal power across commercial, industrial, and public buildings. These systems are configured to provide exit identification and emergency illumination in accordance with established life-safety requirements, assisting facilities in maintaining inspection readiness and operational continuity. For specification criteria related to emergency duration, system configuration, and regulatory alignment, consult the exit and emergency lighting buying guide to support compliant planning.
This collection includes exit signs, emergency lighting units, and combination fixtures commonly specified for corridors, stairwells, and open interior spaces. Products are typically evaluated based on visibility performance, emergency duration, electrical configuration, testing provisions, and UL 924 listing to assist designers, contractors, and facility teams in maintaining compliant life-safety lighting systems.

Technical FAQs for Commercial LED Exit and Emergency Lighting
Engineering reference: See our exit and emergency lighting buying guide for code considerations, battery requirements, testing protocols, and fixture selection used in life-safety lighting systems.
What is the purpose of LED exit and emergency lighting?
Exit and emergency luminaires are installed to help provide visibility during power interruption so occupants can locate egress pathways and navigate toward building exits. These systems are typically required by life-safety codes and must remain operational when normal power is unavailable.
What is the difference between exit signs and emergency lights?
Exit signs identify the path of egress, while emergency luminaires provide illumination along that path. Many facilities deploy both fixture types together within LED exit and emergency lighting systems to support safe building evacuation.
When are emergency lighting systems required?
Requirements are generally established by building and life-safety codes and typically apply to occupied commercial structures. Areas such as corridors, stairwells, assembly spaces, and exit pathways commonly require illumination during loss of normal power. See the exit and emergency lighting buying guide for regulatory context.
How long must emergency lighting operate during a power failure?
Many life-safety standards require emergency luminaires to provide illumination for a defined duration sufficient to support safe evacuation. Battery capacity and system configuration should be verified to ensure alignment with applicable codes.
What are emergency backup drivers and when are they used?
LED emergency backup drivers allow selected luminaires to continue operating at a reduced output during a power interruption. They are often used when maintaining illumination from the primary fixture supports the overall egress strategy.
How should fixture placement be determined for egress pathways?
Placement should support continuous illumination along the path of travel while minimizing shadows that could obscure obstacles. Photometric evaluation helps confirm that light levels remain adequate throughout the egress route.
What is the difference between maintained and non-maintained emergency fixtures?
Maintained luminaires operate during normal conditions and remain illuminated when power is lost. Non-maintained fixtures activate only during an outage. Selection should reflect the operational strategy of the facility.
Do exit signs require continuous power?
Exit signage is typically energized at all times so that the egress path remains clearly identified. Integrated battery systems help maintain visibility when normal power is interrupted.
How important is testing for emergency lighting systems?
Routine testing helps verify that batteries, charging circuits, and lamps operate as intended. Many facilities follow scheduled testing intervals to help confirm system readiness.
What electrical characteristics should be reviewed before specifying emergency fixtures?
Confirm input voltage compatibility, charging requirements, circuit configuration, and transfer behavior during a power interruption. Electrical planning should support reliable activation when normal power is lost.
Can emergency lighting be integrated with standard ceiling fixtures?
Some facilities incorporate emergency drivers into overhead luminaires such as LED troffer lights or LED panel lights to help maintain illumination along egress routes while preserving ceiling consistency.
What correlated color temperature is commonly specified for emergency lighting?
Color characteristics are often selected to remain visually consistent with surrounding luminaires so that transitions during a power interruption do not create confusion within the environment.
How does fixture visibility influence emergency preparedness?
Luminaires positioned where occupants can easily identify the direction of travel help support faster recognition of exit pathways during an outage.
What factors influence long-term serviceability of emergency lighting systems?
Evaluate battery accessibility, component replaceability, charging design, and warranty terms before standardizing a fixture family. Consistent equipment across a facility can simplify inspection and maintenance planning.
How do exit and emergency fixtures fit into an overall lighting strategy?
Life-safety luminaires operate alongside general lighting systems to help maintain visibility during abnormal conditions. Integrating emergency capability into the broader lighting plan supports operational continuity.
