Battery Backup Emergency Lights

battery backup emergency lights provide essential illumination during power outages, ensuring safe egress and code compliance in commercial, industrial, and public facilities. Required by NFPA 101, OSHA, and local codes, these self-contained LED fixtures activate automatically to light hallways, stairwells, and exit routes. Explore wet-location emergency lights, recessed emergency lights, and low-profile architectural emergency lights.

Buyers Guide Tips

What to Look for in Battery Backup Emergency Lights

  • UL 924 & runtime: Verified 90-minute battery backup with compliant photometrics.
  • Battery chemistry: Ni-Cd, NiMH, or Li-ion/LiFePO4—compare recharge time, temperature range, and cycle life.
  • Diagnostics: self-testing emergency lights automate monthly/annual checks.
  • Mounting & power: Universal plates; dual-voltage 120/277 VAC inputs; adjustable heads for corridor spacing.
  • Environment: Damp/wet ratings as needed; for harsh sites consider NEMA-rated emergency lights.
  • Remote capacity: remote-capable emergency lights with battery backup to power extra heads.
💡 What is battery backup emergency lighting? A system that seamlessly switches from AC to internal battery power during an outage, providing regulated illumination for at least 90 minutes as required by national life safety codes.

All models feature internal, maintenance-free batteries—Ni-Cd, NiMH, or lithium-ion—that switch on automatically during a power failure. Each unit delivers a minimum of 90 minutes of emergency lighting to keep paths of egress visible. LED designs provide bright, efficient output while reducing maintenance and operating costs.

Installation is straightforward: universal mounting plates and dual-voltage inputs (120/277 VAC) come standard on most units. Aim light precisely using adjustable heads to cover warehouse aisles, corridors, or open floor plans. For automated maintenance, choose self-testing emergency lights; in corrosive, wash-down, or dusty environments, upgrade to NEMA-rated emergency lights.

Expanding coverage? Use remote-capable emergency lights with battery backup to power additional remote heads from a single fixture—streamlining layout and simplifying service.

FAQs About Battery Backup Emergency Lights

How long do battery backup emergency lights stay on?

Compliant units provide at least 90 minutes of illumination during a power outage per UL 924 and NFPA 101.

What batteries do these lights use?

Common chemistries include Ni-Cd, NiMH, and lithium-ion/LiFePO4. Lithium options are lighter, recharge faster, and offer longer cycle life.

Do I need to test them?

Yes—perform a monthly 30-second functional test and an annual 90-minute full-discharge test. Self-testing models automate these checks.

Where should they be installed?

Place units along paths of egress—corridors, stairwells, exit doors, and large open areas—to maintain required illumination levels during an outage.

How do I verify compliance?

Check for UL 924 listing, confirm 90-minute runtime, and review the product’s testing/diagnostics features to support NFPA 101 readiness.

Can I retrofit existing fixtures?

Often yes. Some systems support remote heads or battery backup kits. Verify electrical compatibility, available wattage, and mounting before specifying.

How long do batteries last before replacement?

Typical service life is 3–5 years depending on chemistry and environment. Routine testing helps identify when replacement is due.

Do I need damp or wet-location ratings?

Use damp-location units for humidity or condensation. Choose wet-location models for direct spray, wash-down, or exterior exposure.
