What’s Covered in This Guide
Overview: Choosing an Exit Sign
Choosing the right exit sign for your facility is an important part of emergency planning and code compliance. Today’s market offers a wide range of exit sign types, each with specific applications, price points, materials, maintenance requirements, and design aesthetics. Whether you're looking for high-end finishes or budget-friendly models, understanding the differences can help you make an informed decision.
LED Exit Signs are popular for their energy efficiency, long lifespan, and affordable pricing.
Non-Electrical Exit Signs
For indoor applications, you’ll first need to decide between electrical and non-electrical exit signs. Electrical exit signs use LED (light-emitting diode) technology to illuminate EXIT in red or green. Non-electrical signs include:
- Photoluminescent exit signs – glow in the dark after absorbing ambient light.
- Self-luminous exit signs – exit sign powered by tritium gas and require no external power source.
Non-electrical models are ideal for off-grid installations and offer operating lifespans of up to 25 years without electricity or maintenance.
LED Exit Signs
LED exit signs are a smart choice when power is readily available. These cost-effective models start under $20 and come in thermoplastic housings—typically in white or black. All include integrated battery backup systems for 90-minute operation during power outages.
Cast Aluminum Exit Signs offer durability and upscale design finishes.
Die-Cast Aluminum Exit Signs
Die-cast aluminum exit signs are a premium option featuring rugged housings in brushed aluminum, black, or white. These signs combine LED efficiency with architectural appeal. They are suitable for a wide range of applications—from factories to fine dining establishments—and are highly resistant to corrosion and wear.
In accordance with the National Electrical Code (NEC) Article 700-16, emergency lighting and exit signs must operate for 90 minutes during a power outage. All electric signs with backup batteries comply with this standard. While the NEC provides national guidelines, always follow your local authority having jurisdiction (AHJ) for final approval.
Aluminum Exit Sign Technology
Modern aluminum LED exit signs consume less than 5 watts of energy and provide 8–10 years of continuous use. Compared to older incandescent exit signs, they offer dramatic savings in power and maintenance costs over their operational lifespan.
Understanding LED Technology in Exit Signs
LEDs (Light Emitting Diodes) are cooler, more durable, and longer-lasting than incandescent bulbs. This advancement has enabled compact, stylish, and energy-efficient exit sign designs—perfect for businesses seeking both form and function.
Today’s exit signs range from sleek acrylic edge-lit models to rugged steel units certified for hazardous locations. With so many styles available, it's wise to consult with local code officials and product experts to ensure the right solution for your needs.
Edge-Lit Exit Signs
Edge-Lit LED Exit Signs offer high-end appeal with modern aesthetics.
Edge-Lit LED Exit Signs are the premium choice for contemporary interiors. These models use a high-grade acrylic panel etched with “EXIT” lettering and illuminated from the edge by hidden LEDs. Available in surface and recessed mount options, Edge-Lit signs offer a seamless, low-profile look unmatched by standard signs.
Outdoor & Harsh Environment Exit Signs
For exterior applications, you can choose between:
- Wet Location LED Exit Signs – Feature sealed fiberglass housings to resist rain, snow, dust, and humidity. Optional internal heaters ensure battery backup performance in freezing temperatures.
- Tritium-Powered Exit Signs – Powered by tritium gas and require no electricity, battery, or maintenance. These signs are especially popular in remote or outdoor environments.
Self-luminous exit signs require no electricity or batteries and last up to 20 years.
Thanks to their simple installation, zero maintenance, and long lifespan, self-luminous exit signs have become one of the most widely used solutions for outdoor exit applications.
