An emergency light is a lighting device with a battery backup that switches on automatically when a building experiences a power outage. Emergency lights are standard in commercial and high occupancy residential buildings, such as college dormitories. Most building codes require emergency lighting be installed in older buildings as well.
Visibility, brightness and long life are very important factors that should be thought about when purchasing and exit sign. Light emitting diode or LED exit signs & emergency lights have proven to be successful in the reducing electricity consumption by up to 85%. LED exit signs can save money and power while still emitting considerable amounts of light.
Exit sign combo units are really a 2 for 1 solution and are the ideal solution where you need to install both an exit sign & an emergency light near each other. Exit combos allow you to maintain just one battery and unit while meeting two code requirements. There is a combo exit sign for almost every application and location.
An emergency light with battery backup capability switches to emergency operation in the event of a power loss to illuminate escape routes and safety equipment.
Hazardous location exit signs and emergency lights are designed to operate in hostile environments that would damage ordinary signs and lights. Constructed from corrosion resistant materials, some units offer sealed enclosures that can be used in outdoor environments or areas subject to water spray, moisture and extreme temperature conditions.
