What to Look for in Damp Location Emergency Lights

  • UL Damp Location Rating: Certified for areas with moisture/condensation (garages, basements, covered entries).
  • Sealed Housing: Gasketed enclosure to prevent moisture ingress and protect battery/electronics.
  • Corrosion-Resistant Materials: Thermoplastic or powder-coated steel/aluminum to resist rust, mildew, and chemicals.
  • Battery Backup: 90-minute runtime to meet UL 924, NFPA 101, and OSHA.
  • Self-Testing Option: Automated monthly/annual diagnostics to simplify inspections.
  • Installation Flexibility: Universal plates + adjustable lamp heads for corridors/stairwells.
  • Upgrade Path: Direct spray/wash-down → choose a wet-location rated fixture.
What is a damp location emergency light?
A damp location emergency light is a UL 924–listed egress fixture designed for humid interiors where moisture is present but no direct water spray. Typical builds use gasketed housings, corrosion-resistant hardware, LED heads, and a 90-minute battery backup—ideal for garages, stairwells, laundry rooms, and covered walkways.

Damp-rated housings use gaskets, corrosion-resistant hardware, and smooth surfaces that resist buildup. Popular constructions include thermoplastic, aluminum, and coated steel for longevity in garages, stairwells, and utility corridors.

All models provide at least 90 minutes of emergency illumination to meet UL 924 and NFPA 101. Many add self-diagnostics for automated monthly/annual checks and remote capacity to power additional heads from one unit.

Installation is straightforward with universal backplates for wall/ceiling mounts, dual-voltage 120/277 VAC input, and adjustable LED optics to aim light along egress paths. For spaces exposed to direct spray or wash-down, upgrade to wet-location rated emergency light fixtures or NEMA-rated emergency lighting.

Damp Location Emergency Lights Spec Guide

Spec Snapshot

  • Compliance: UL 924 listed with a minimum 90-minute runtime; supports NFPA 101. Rated for damp locations (humidity/condensation, no direct spray). Use wet-location/NEMA enclosures for wash-down or exposure.
  • Housing & Ingress: Sealed, gasketed construction with corrosion-resistant hardware and moisture-tolerant electronics for garages, stairwells, vestibules, and covered corridors.
  • Battery & Electronics: Maintenance-free Ni-Cd or lithium (e.g., LiFePO4); solid-state charger/automatic transfer, low-voltage disconnect, AC lockout, brownout detection, push-to-test & status LED.
  • Optics & Output: High-efficacy LED heads with adjustable aim; review manufacturer photometric data to meet corridor/stair spacing targets at planned mounting height.
  • Power: Dual-voltage 120/277 VAC input; confirm wire/knockout locations and conduit path for sealed installs.
  • Mounting: Universal wall/ceiling backplates with keyholes and knockouts; ensure orientation for best sightlines and egress coverage.
  • Diagnostics: Self-testing versions automate monthly 30-second and annual 90-minute tests and report faults—useful for hard-to-access locations.
  • Options: Remote-capable variants to power extra heads (verify available remote wattage/runtime), vandal-resistant housings, and cold-weather packages if ambient dips near freezing.

FAQs About Damp Location Emergency Lights

What qualifies as a “damp location”?

A damp location is an area subject to humidity or occasional moisture—like garages, basements, covered outdoor walkways, or utility rooms. These spaces are not directly exposed to rain or water spray.

How are damp-rated lights different from wet-location lights?

Damp-rated fixtures are sealed to withstand humidity and condensation, but they are not designed for direct water exposure. For areas exposed to rain, hose-downs, or splashes, use wet-location rated emergency lights.

Are these lights code compliant?

Yes. Damp-rated emergency lights that meet UL 924 and NFPA 101 provide the required 90 minutes of backup illumination and meet OSHA life safety standards.

Can I use a standard indoor unit in a damp location?

No. Standard indoor emergency lights are not designed to resist moisture. Using them in damp environments can lead to corrosion, failure, and code violations.

Do damp-location lights include battery backup?

Yes. All models include built-in batteries for emergency operation. See our battery backup units for more details.

Are self-testing models available?

Absolutely. Self-testing emergency lights are available in damp-rated designs and help automate code-required inspections.
