A lighted exit sign is a rectangular box with electric-light bulb inside it. It also has two hollow cylindrical hinges for balanced support. Lighted exit signs are predominantly used in theaters, stadiums, companies, colleges, schools, etc. The text EXIT is either displayed in English or in the local language. These signs are made according to OSHA, UL-924, NEC standards.
Many exit signs come along with a battery backup, so that they remain lit even during power failure. Lead batteries are the most recommended ones for exit signs, because of their long-lasting quality. During power failure, the lead battery lights the Exit sign in no time. Thus, you witness that the exit signs are always lit.
LEDs are light emitting diodes. Most of the exit signs use LED technology. Since LEDs are splinter proof and resistant to moisture, they are the safest and most preferred exit signs. They consume less energy and hence are the greenest solution available. Most of the signs are long-lasting and require minimum maintenance. However, exit signs may stop working during accidents and calamities like fire and flood. In most countries, the exit sign is green because, the color red usually indicates prohibited activities.
Some exit signs are independent and do not require battery or electricity. They work on tritium instead of electricity. For the sake of safety, tritium is sealed in a glass tube. Exit signs of this kind, are referred to as self-luminous exit signs. They work on the same mechanism as fluorescent lights do. In some areas, usage of self-luminous exit signs is prohibited. Since these exit signs contain radioactive substances, care should be taken while disposing them. They are also considered the most expensive exit signs.
