Buying Guide
- Backup duration: Determine whether 90 minutes or longer is needed based on egress requirements and building codes.
- Light output and coverage: Compare lumens and beam patterns. For long corridors, prioritize higher total lumens and wider lenses.
- Installation flexibility: Look for universal mounting options, swivel heads, and easy-release components to simplify maintenance.
- Durability and location: Choose flame-rated housings for indoors and die-cast aluminum for outdoors or damp locations.
- Self-diagnostics and test features: Self-test diagnostics help ensure readiness without manual testing; consider remote test or EZ test options if maintenance is a concern.
- Environmental compatibility: Confirm IP ratings (Wet/Dry location) and temperature ranges align with installation sites.
- Compliance: Ensure fixtures meet UL 924 or equivalent standards for emergency lighting in your jurisdiction.
Frequently Asked Questions
What is self-diagnostic emergency lighting?
Lighting fixtures that automatically check their own battery, lamp, and circuitry status and report faults without manual testing.
How long should emergency lights operate during an outage?
Most commercial fixtures provide 90 minutes of backup illumination, but some models offer longer runtimes.
Can emergency lights be used outdoors?
Yes, many models feature weatherproof housings and IP ratings suitable for wet or damp locations.
What maintenance is required for self-diagnostic lights?
Regular inspections and battery replacements per code; self-diagnostics reduce manual testing needs but do not eliminate required maintenance.
Do I need to match fixtures to a specific wiring or control system?
Yes. Verify voltage compatibility (e.g., 120–277V) and confirm any photocell or external control integration.
