Emergency & Exit Lighting
Emergency and exit lighting switches on automatically when normal power fails, lighting escape routes and marking exit doors so occupants can leave a building safely. NLS sources self-contained and central-battery emergency luminaires and illuminated exit signs built to IEC 60598-2-22, sized for the escape-route autonomy time a project's fire strategy specifies, for hospital and industrial buildings across Saudi Arabia.
Emergency and exit lighting is the life-safety layer that activates the instant normal power is lost, whether from a utility outage or a fire-related shutdown, and stays lit long enough for a building's occupants to reach an exit. The category splits into two supply architectures: self-contained luminaires with an integral battery and charger inside each fixture, simple to install and add to an existing circuit, and central battery systems where one battery bank in a dedicated room feeds all emergency luminaires on a building through a monitored circuit, which centralizes maintenance and testing at the cost of a more involved cable design.
IEC 60598-2-22 sets the particular requirements for luminaire construction, and the required duration a fixture must stay lit, typically 1, 2, or 3 hours depending on the building's evacuation strategy, comes from the fire engineering or life-safety design rather than a fixed universal number. Illuminated exit signs (running or static pictogram) follow the same duration logic and need to stay legible from the specified viewing distance for the sign size chosen.
Hospitals carry the strictest emergency lighting requirements of any building type NLS supplies into, since corridors, operating theatres, and critical care areas can't tolerate a gap between power loss and emergency light activation, and a central battery system with a monitored self-test function is generally the specified approach over standalone self-contained units. NLS already supplies hospital and aviation infrastructure across Saudi Arabia, and sources emergency and exit lighting for exactly this class of critical building alongside industrial facilities where the same escape-route logic applies.
A project team typically sends the fire strategy's required duration, the self-contained or central battery architecture specified, and a fixture count or layout, and NLS returns a matched product recommendation and USD quote. Central battery components generally carry a longer lead time than standard self-contained fixtures because the battery bank and charger unit are sized to the specific building load.

Frequently Asked Questions
What's the difference between self-contained and central battery emergency lighting?+
Self-contained fixtures carry their own battery and charger, simple to install fixture by fixture. Central battery systems feed every emergency luminaire in a building from one monitored battery bank in a dedicated room, which centralizes testing and maintenance but needs a more involved cable design, and is generally specified for hospitals and larger critical facilities.
How long must emergency lighting stay on during a power failure?+
The required duration, typically 1, 2, or 3 hours, comes from the building's fire engineering or life-safety strategy, not a single fixed rule. Hospitals and large occupancy buildings usually specify the longer end of that range.
Who supplies emergency and exit lighting for hospitals in Saudi Arabia?+
NLS sources self-contained and central-battery emergency and exit lighting matched to hospital fire-strategy requirements, alongside the hospital and aviation infrastructure NLS already supplies in Saudi Arabia.
