Wet-Location LED Emergency Light – Dual 1 W Heads, Vandal-Resistant Design, 18 ft Spacing — Features & Specs
The LEM54-N4 wet-location thermoplastic LED emergency light delivers dependable, code-compliant egress illumination for outdoor entries, breezeways, wash-down areas, and harsh indoor environments. Two adjustable 1 W LED heads provide up to 18 ft spacing on a 3 ft path (sample photometrics), powered by a 90-minute Ni-Cd battery. Its slim, UV-stable polycarbonate housing is UL 924 listed for wet locations, and the stainless hardware with waterproof shield/gasketing resists corrosion, hose-down spray, and impact.

Key Features
- Two fully adjustable 1 W LED heads; sample photometrics indicate 18 ft center-to-center on a 3 ft path at 7.5 ft mounting height (~12 ft on a 6 ft path).
- 90-minute emergency runtime with typical 24-hour recharge.
- Dual-voltage 120/277 VAC input; solid-state transfer, low-voltage disconnect (LVD), brownout protection, and push-to-test.
- UV-stable, corrosion-resistant thermoplastic (UL 94 V-0) and stainless hardware in a vandal-resistant design.
- Wet-location construction for damp, wet, and hose-down areas (gasketed shield and fasteners).
- Ceiling or wall mount: universal 3"/4" J-box pattern and rear keyholes; optional IHB bracket for poles, strut, and I-beams.
- Finishes: Black or White. Compact profile: 13.3" W × 5.8" H × 5.4" D.
Applications & Design Notes
Choose this model for sites that need a tough, compact wet-location LED egress fixture with straightforward installation and predictable spacing—exterior vestibules, covered landings, loading alcoves, rooftop access doors, cold-room anterooms (above 10 °C), and wash-down corridors. The 36° beam helps you cross-aim the two heads to overlap footprints and minimize shadows at stair treads and ramps. For projects requiring remote heads or higher wattage, consider remote-capable alternatives in our weatherproof emergency lights collection.

FAQs
Can this unit be mounted on the ceiling outdoors?Yes. It supports wall or ceiling mount with a universal J-box pattern. Ensure the box is weather-tight and seal conduit penetrations for wet zones.
How do I achieve the 18 ft spacing noted?Mount around 7–8 ft and cross-aim the two heads to overlap beams. Always confirm foot-candle levels at 90 minutes under site conditions and local code.
Do I need a remote-capable model instead?This model is not remote-capable. If you need to drive remote heads from the fixture, consider a remote-capable wet-location unit or a higher-capacity NEMA 4X MR16 platform.
