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). Emergency lighting lamps are usually PAR 36 sealed beams or wedge-shaped base lamps. All units have some kind of equipment to focus and enhance the light they produce. It can be a plastic cover above the fixture or a reflector placed behind the light source. Most single light sources can be rotated and aimed at the places where light is most needed in emergencies, such as toward fire exits. Modern lamps usually have some kind of test button. Even if the main power is still on, the button will temporarily cover the device and turn it on and use battery power. Modern systems operate at relatively low voltages, usually 6 to 12 volts. This reduces both the size of the required battery and the load on the circuit to which the emergency light is connected. Modern lamps include a small transformer in the base of the lamp, which reduces the voltage of the main current to the low voltage required by the lamp. The battery is usually made of lead calcium, and it 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.
