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.
The main housing of these exit signs and emergency lights is painted white or made from a white thermoplastic.
Recessed mounted exit signs or emergency lights offer a low-profile installation by hiding the housing, which includes the electrical components of the exit sign in the ceiling.
This feature may be added to many exit sign and emergency light fixtures, the SDT feature prolongs battery life, and reduced man hours required OSHA tests. Self testing diagnostic automatically executes a 15 minute test every 30 days and runs a 90 minutes test once per year. The major reasons batteries typically fail is because they remain dormant for long periods of time. With the SDT feature automatically simulates a full discharge and full recharge to keep the batteries in peak performance. If any problems arise during this testing process it will report them through the user interface. This benefit drastically reduces man hours required by OSHA to manually perform the tests.
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.
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.
Emergency inverters keep your lights on in uncertain situations. Interruptible inverters have a slight delay before power is restored while uninterruptible inverters maintain the power load, without fluctuation, during an outage.
Exit signs & emergency lights that are surface mountable are typically one sided and have a back plate that can be connected directly to a wall or flat surface.
Commercial lighting is lighting used for commercial spaces such as offices, stores, institutions, hospitals and government buildings, essentially those spaces that are not residential, industrial or for manufacturing.
