Power Free, Photoluminescent “glow-in-the-dark” Exit Signs

Image of UL 924 listed photoluminescent exit signPhotoluminescent signs, often referred to as “glow-in-the-dark” signs, absorb and store energy from normal ambient light, then release this energy in the form of a visible glow when the lights go out. Photoluminescent products automatically recharge once the lights are turned on, requiring approximately 60 minutes of exposure to 5 foot-candles or 54 LUX of natural light, fluorescent, metal halide or mercury vapor light. [ A 100W incandescent bulb produces about 1750 lumens or 137 foot-candles. A 23 watt fluorescent light produces about 1600 lumens or 125 foot-candles. ]

In the event of a power failure UL 924 listed photoluminescent exit signs are immediately visible from a distance of 50 to 75 feet. Current photoluminescent materials have a much longer and brighter glow compared to old materials, helping to speed evacuation during a lights-out emergency.

This failsafe technology works without electricity. Photoluminescent exit signs are completely power free, requiring no electricity (AC) or batter power to operate. Since no electrical connection is required, installation is very easy. Plus, with no power consumption, no electronics, no batteries to replace and no bulbs to burn out or break, these signs provide zero operational or maintenance costs over the lifetime of the product. Industrial-grade photoluminescent tapes and signs are designed to withstand normal wear and tear, making them a reliable solution that is “always ready” in an emergency.

A Proven Solution

Shortly after the tragic events of September 11th, the National Institute of Standards and Technology conducted an investigation into the evacuation process at the World Trade Center. According to the investigation, existing photoluminescent markings in the stairwells was one of the most commonly reported forms of aid in evacuating the buildings. As a result, the city of New York passed Local Law 26, requiring the installation of photoluminescent exit signs and floor level exit pathway markings in all commercial high rise buildings over 75 feet tall. Residential, hospital, hotel and educational buildings are installing photoluminescent exit signs and egress markings on a voluntary basis.

We recommend photoluminescent fixtures and markings as a reliable, energy efficient and cost effective solution to prepare for a lights-out emergency in your facility.

Demystifying power-free, self luminous, Tritium Exit Signs

Self-luminous EXIT signs containing the radioactive gas tritium are widely used in a variety of facilities across the United States, such as public and private office buildings, theaters, stores, schools and churches – anywhere the public needs a rapid exit path. Those who possess tritium EXIT signs are general licensees of the Nuclear Regulatory Commission or an Agreement State, and are subject to certain reporting and handling requirements, including proper disposal of unwanted or unused signs. Tritium EXIT signs pose little or no threat to public health and safety and do not constitute a security risk.” — United States Nuclear Regulatory Commission, Fact Sheet on Tritium EXIT signs

Are Tritium Exit Signs bright enough?

While tritium lamps are not visible when normal lighting is on in a building, the UL 924 required contrast ration of the face color makes the exit sign very visible when the normal lighting is off. In fact, the brightness of a Tritium Exit sign is over double the minimum requirement set by UL 924.

 

Are Tritium Exit Signs UL 924 approved?

Yes, all tritium exit signs sold by The Exit Light Company have a UL 924 listing for exit signs.

 

Which types of installations are ideal for Tritium Exit Signs?

Tritium is a perfect choice when: there is not enough ambient light to charge a photoluminescent sign; there is no electrical power supply to the location; environments where electricity could ignite particles in the environment; where zero power consumption and no maintenance cost is desired.

What is the real purpose behind lighted LED exit signs?

Power outages occur in businesses, educational and medical facilities across the country every day. Are you prepared for such an emergency? Many people think that the sole purpose of an exit sign is to mark stairwells and building exits. However, that is only a secondary purpose for lighted LED exit signs.

 

Image of lighted red LED exit signThe real function of lighted LED exit signs is to allow you to find the exit or emergency egress route in the event of an emergency situation. Many times a power outage can be the result of a fire in the building. In such cases, finding the emergency exits can be complicated not only by a loss of power but from the presence of smoke in emergency egress routes. Under these circumstances, lighted exits signs powered by rechargeable backup batteries can literally save lives by allowing individuals to safely exit the building.

 

Most relevant codes (fire, building, health or safety) require exit signs to be permanently lit. The use of light-emitting diode (LED) technology provides brighter illumination than incandescent lamps, resulting in better visibility in a fire situation. LED exit signs also consume much less energy than traditional incandescent models, typically requiring about 4 watts of power to operate. This results in significant cost savings over the life span of the fixture, especially considering that LEDs have a very long life and may last for 10 or more years of continuous use.

April 2009 – Featured Product Showcase

The “Featured Products” area of our storefront showcases those products that we feel are exceptional because of their value, design, or quality. We recently added a product which we feel meets all three of those criteria.

 

We are pleased to offer a line of specially priced “Cast Aluminum Exit Signs” which include self-testing diagnostic capabilities and an additional brushed aluminum faceplate at a fantastic price.

 

National safety regulations require that all exit signs be tested for functionality once every twenty-eight days for five minutes and ninety minutes every six months. This testing is time-consuming and labor intensive, especially in facilities/locations with a large number of installed signs. A self testing exit sign will perform routine self-diagnostics and warn you when there is a problem. This functionality can provide a significant cost savings over the lifetime of the product.

 

The aluminum faceplates have “knock-out” left and/or right chevrons which can be removed to indicate direction of emergency egress. The second faceplate allows for double-sided installations. The “knock-out” chevrons and double faceplates allow these signs to be fully configurable for every conceivable installation type.

 

These are exceptional values and will not last for long. What’s keeping you from enjoying the architectural beauty of cast aluminum exit signs today?

 

As always, thank you for your continued support.
