Modern emergency lighting is installed in almost every commercial and high-occupancy residential building. The lamp consists of one or more incandescent bulbs or one or more high intensity light emitting diodes (LEDs). The emergency light is usually a PAR 36 sealed beam or a wedge shaped base light. All units have some kind of equipment to focus and enhance the light they produce. It can be a plastic cover over the fixture or a mirror placed behind the light source. Most individual light sources can be rotated and aimed at where light is most needed in an emergency, such as toward a fire exit. Modern luminaires usually have some kind of test button that temporarily covers the device and turns it on and uses battery power, even if the main power is still on. Modern systems operate at relatively low voltages (typically 6 to 12 volts). This reduces both the size of the battery required and the load on the circuit to which the emergency light is connected. Modern luminaires include a small transformer in the base of the luminaire that reduces the voltage of the main current to the low voltage required by the lamp. The battery is usually made of lead calcium and can be used for 10 years or more for continuous charging. During a power outage along the exit path, US fire safety regulations require at least 90 minutes of battery power.
In order to indicate that a power outage has occurred, some models of emergency lights can only be manually turned off after activation, even if the main building's power is turned back on. The system will remain lit until the reset button on the side of the device is pressed.
An emergency light is a battery-powered lighting that automatically turns on when a building loses power. Emergency lights are standard in new commercial and high-occupancy residential buildings, such as university residences, apartments and hotels.
