NEMA Rated Exit Sign and Emergency Light Combos – Durable Solutions for Harsh Environments

NEMA-rated exit sign and light combos are engineered to perform in the most demanding conditions—offering all-in-one egress safety with protection against water, dirt, dust, and corrosion. These weatherproof, impact-resistant units combine an illuminated EXIT sign with integrated emergency lighting, all enclosed in NEMA 4X or NEMA 12-rated housings. Perfect for industrial washdown rooms, chemical plants, refrigerated storage, outdoor mechanical areas, and sanitary environments, they are built to last where traditional fixtures fail.

Each combo fixture meets UL 924, NFPA 101, and OSHA emergency egress standards. Inside, the self-contained battery delivers a full 90 minutes of backup lighting during power loss. Outside, the enclosure—often made of UV-resistant polycarbonate, fiberglass-reinforced plastic, or powder-coated aluminum—is fully gasketed and sealed to block out moisture, chemicals, and airborne particulates. Security-grade fasteners and sealed optics help prevent tampering and water intrusion in high-abuse zones.

Designed for versatility and compliance, most models support dual-voltage operation (120/277 VAC), and include field-selectable arrow indicators and adjustable LED lamp heads that provide targeted illumination. High-efficiency output using MR16 or ultra-bright LEDs ensures excellent spacing and coverage. Many fixtures feature self-testing circuitry that performs automated diagnostics, helping you streamline maintenance tasks and remain inspection-ready at all times.

Mounting is made simple with universal installation kits supporting ceiling, wall, or pendant configurations. Whether you're upgrading an existing warehouse or designing a compliant food-processing facility, these units offer efficient installation and robust long-term operation.

If you need other heavy-duty safety fixtures, explore our range of weather-sealed NEMA exit signs, moisture-resistant emergency lights, or UL wet-location exit sign combos for additional industrial-grade configurations tailored to harsh environments.

Frequently Asked Questions

❓ What does a NEMA 4X or NEMA 12 rating mean?

NEMA 4X and 12 ratings indicate the fixture is sealed against dust, water spray, and corrosion. NEMA 4X adds protection for outdoor or washdown areas, while NEMA 12 is ideal for indoor industrial use with non-corrosive liquids and dust.

❓ Can these combo units be used outdoors?

Yes. NEMA 4X-rated units are suitable for outdoor and wet environments, including rain, hose-downs, and high-humidity locations.

❓ Are the LED light heads adjustable?

Most models come with fully adjustable lamp heads that can be aimed to optimize corridor and stairwell illumination during an emergency.

❓ How do I know if my combo unit is functioning properly?

Units with self-testing diagnostics will automatically perform monthly and annual tests. An indicator light will alert you if maintenance or battery replacement is needed.

❓ Where are NEMA-rated combos typically installed?

These units are commonly used in food processing areas, manufacturing plants, wastewater treatment facilities, outdoor exits, and other rugged or wet environments where traditional exit signs and lights would fail.
