Wet Location Emergency Lights — UL 924 outdoor egress fixtures with battery backup

Wet Location Emergency Lights

Wet location emergency lights—also called outdoor emergency lights—are egress light fixtures engineered for direct exposure to rain, humidity, and wash-downs. These units provide battery backup for the path of egress.

Buyers Guide Tips

What to Look for in Wet Location Emergency Lights

  • Ingress protection (degree of protection): Specify IP65/IP66 or NEMA 4X for direct rain, spray, and wash-down; use gasketed doors and sealed conduit entries.
  • Egress compliance: Confirm UL 924 listing with a verified 90-minute runtime at the stated temperature range.
  • Temperature rating: Check minimum/maximum ambient; add cold-weather heater kits for freezer docks and winter climates.
  • Materials & corrosion: Thermoplastic, fiberglass, or powder-coated aluminum with stainless hardware and protection against corrosion for coastal/chemical exposure.
  • Lamp heads & optics: Adjustable LED heads; select lumen package/beam to meet corridor and door foot-candle targets.
  • Power & charging: Dual 120/277 VAC, solid-state charger, automatic transfer, brownout protection, and low-voltage disconnect.
  • Battery chemistry: Ni-Cd or lithium sized for temperature and recharge time; verify service life and maintenance intervals.
  • Diagnostics: Self-testing availability with clear status/fault indicators and a manual test switch accessible from floor level to speed inspections.
  • Mounting & sealing: Wall/ceiling options; ensure gaskets, weep holes, and drip edges are oriented correctly during install.

Whether you're lighting stair towers, outdoor walkways, loading docks, or mechanical rooms, wet location emergency lights (our most common outdoor emergency lights) ensure safe, code-ready egress during power outages. Most units are UL 924 compliant and meet NFPA 101 and OSHA life safety codes, delivering at least 90 minutes of runtime. For interior corridors and general-purpose egress, see our battery backup emergency lights.

Choose models with a wet location rating and the right degree of protection—IP65/IP66 or NEMA 4X—plus options for high-lumen output and tamper-resistant enclosures. Fully enclosed internal components and water-resistant housings in thermoplastic, fiberglass, or powder-coated aluminum withstand rain, humidity, UV, and physical abuse in exterior environments.

💡 Pro Tip:
Use outdoor emergency lights in any area exposed to water, spray, or wash-downs—like car washes, parking structures, commercial kitchens, outdoor stairwells, and marine-grade enclosures.

Wet Location Emergency Lights – Spec Guide

  • Ingress protection: Specify IP65/66 or NEMA 4X for direct rain, hose-down, and spray; require gasketed doors and sealed conduit entries/hubs.
  • Egress compliance: UL 924 listing with verified 90-minute runtime at the stated ambient; coordinate illuminance/spacing with NFPA 101 (AHJ).
  • Temperature range: Confirm min/max ambient; add cold-weather heater kits for freezer docks/winter climates and high-temp options for boiler/mechanical rooms.
  • Materials & corrosion: Thermoplastic, fiberglass (FRP), or powder-coated aluminum with stainless hardware; consider marine/coastal finishes and anti-UV stabilization.
  • Lamp heads & optics: Adjustable LED heads; select lumen package and beam (spot/flood) to meet door/corridor foot-candles and target spacing at mounting height.
  • Power & charging: Dual 120/277 VAC, solid-state charger, automatic transfer, brownout protection, low-voltage disconnect, and surge suppression.
  • Battery chemistry: Maintenance-free Ni-Cd or lithium sized for ambient and recharge time; verify service life and PM intervals; consider remote-capacity models if needed.
  • Diagnostics: Self-testing capability for automated monthly 30-sec and annual 90-min tests; require floor-visible status/fault indicators for quick inspections.
  • Mounting & sealing: Wall/ceiling options; verify gasket compression, weep-hole orientation, drip edges, and conduit sealing to prevent water ingress.
  • Durability & impact: Specify impact-resistant lenses, vandal-resistant hardware, and IK/impact considerations for exposed sites and high-traffic areas.

FAQs About Wet Location Emergency Lights

What is a wet location emergency light?

It's an emergency lighting fixture certified to operate safely in environments exposed to rain, hose-down spray, or direct moisture. These lights are UL wet-location rated and fully sealed against water ingress.

Where are wet-location emergency lights typically used?

Common installation areas include parking decks, outdoor stairwells, walk-in freezers, industrial wash-down zones, and any exterior location exposed to the elements.

Do these emergency lights meet code requirements?

Yes. All models are UL 924 listed and compliant with NFPA 101 and OSHA life safety code requirements, including 90 minutes of emergency egress runtime.

Can they handle freezing temperatures?

Many models include low-temperature battery packs or internal heaters for reliable operation in cold-storage areas, freezers, or outdoor structures during winter months.

Do wet-location units include battery backup?

Yes. All models feature a sealed internal battery backup that activates during power outages. See our full battery backup emergency light collection for more options.

Are self-testing models available?

Absolutely. Many self-testing emergency lights are also wet-location rated, making code-required inspections easier in hard-to-reach or high-mount environments.

Do these lights turn on at night or by motion?

No. Wet-location emergency lights activate only during emergencies, such as power failures or fire alarm events. For lighting with motion sensors or dusk-to-dawn control, explore our wall pack light collection.
