Generally, exit signs are short text, indicating the location of the closest emergency exit. There are two types of LED Exit Signs: those that are illuminated with a light source and those that are not.
Glow-in-the-dark signs
Choosing glow-in-the-dark exit signs is a good way to ensure that your building is easy to navigate in the event of an emergency. These signs are also energy-efficient, so you can save money on your electricity bill.
Glow-in-the-dark exit signs glow for up to eight hours. This means that in an emergency, you will be able to locate your exit quickly. Glow-in-the-dark signs are also easy to install. They don’t require electricity, batteries or an electrician. They simply absorb the light from the environment and gradually release the energy back into the surrounding atmosphere.

Photo luminescent signs are also a good way to locate your exits during power outages. They glow for about 18 hours. Photo luminescent signs also have a high visibility, so they can be seen from as far as 50 feet away. Photo luminescent EXIT signs are an energy-efficient way to meet the requirements of your building’s code. They also earn you LEED points.
Incandescent bulbs
Compared to traditional incandescent lights, LED exit signs require less maintenance and are more energy efficient. They also save money in the long run. LED exit signs have a rated life of over 11 years, and require only a few watts to power them. They are also less likely to attract bugs and insects, and they do not burn out like incandescent bulbs.
When you look at the watts used, the newer LED exit signs use only a modest average of 5 watts. That’s a lot less than the 20 to 40 watts used by conventional exit signs. The LED exit signs also have a battery back up. This is especially useful in the event of a power outage. The batteries recharge when the building’s general lighting is on. If you have an older exit sign, you can consider an LED retrofit kit to upgrade the fixture to the newer energy efficient technology.
The wattage rating of each light source varies, but the most energy efficient type is a fluorescent. They are narrow-diameter bulbs that use electronic ballasts and rare earth tri-phosphors. They use about one-fourth the power of incandescent bulbs.
Photo luminescent signs
Unlike traditional exit signs that require constant electricity, photo luminescent exit signs glow in the dark. They’re fail-safe, easy to maintain, and meet code requirements. Photoluminescent exit signs have been approved by the Occupational Safety and Health Administration. This means that they can help to improve the safety of your building while also decreasing its carbon footprint.
Photoluminescent exit signs are used as a safety evacuation directional guidance signage that eases use of exit passageways. They’re also ideal for meeting NFPA 101 life safety requirements.

The International Building Code (IBC) requires luminous egress path markings to be installed in many buildings. These signs should be clean and free of obstructed areas, and they should be checked periodically to ensure that they’re working properly.
Photoluminescent exit signs also meet or exceed Underwriters Laboratories’ minimum requirements for emergency egress signage. They use no electricity and have a life expectancy of about 25 years. They can also help to qualify for LEED credits.
Edge lit signs
Unlike standard box-style exit signs, edge-lit LED exit signs are an elegant and safe alternative for architectural applications. They are designed to mount to the surface of the wall near the exit route door. This gives them a cleaner look and allows for flexible in-field installation.
Edge-lit LED exit signs are available in a wide variety of styles and features. They are UL 924-listed for emergency lighting and offer a long battery life, 90 minutes of battery backup, and consistent illumination. These units are also available in single or double-sided designs.
The BXFO Series features a slim, curved-edge acrylic exit panel, and long-life LED lamps to provide consistent brightness. These units are suitable for surface or recessed mounting. These units can be installed in drywall, drywall masonry, masonry, masonry concrete, drop ceilings, and other architectural applications.
