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.
The main housing of these exit signs and emergency lights is painted black or made from a black thermoplastic.
The nickel–cadmium battery is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation NiCd is derived from the chemical symbols of nickel and cadmium. NiCd batteries have a longer shelf life of around 10 years. The NiCd batteries sold on this site are High Temperature NiCds batteries with outstanding charge/discharge characteristics at both room temperature and high temperature up to 70°C (158°F).
Warning: Batteries, battery terminals, and related accessories can expose you to chemicals including Cadmium and Cadmium compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to https://www.p65warnings.ca.gov
Remote capable exit signs or emergency lights allow the unit to add additional lighting with remote light heads without adding additional fixtures.
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.
NEMA rated enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against the entry of water during prolonged submersion at a limited depth. NEMA 12 enclosures are designed to prevent the ingress of dust, water, and oil.
These products can be hung from the ceiling. Many exit signs come with the ceiling mounting canopy included.
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.
Nickel Metal Hydride (NiMH)
A nickel metal hydride battery, abbreviated NiMH or Ni–MH, is a type of rechargeable battery. A NiMH battery can have two to three times the capacity of an equivalent size NiCd, and its energy density can approach that of a lithium-ion battery.
Architectural lighting is designed to be a highly functional style of lighting in spaces where light fixtures are needed to serve a fundamental purpose, such as providing focused downlight or accenting certain areas of a room. Often thought of as a practical type of lighting, these fixtures are not usually given credit for their decorative character and ability to add undeniable style to a lighting project.
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.
Title 20 is part of the CEC's Appliance Efficiency Regulation and California Code of Regulations that requires
manufacturer certification of "self-contained” lighting control devices in California.
"Self-contained” lighting control devices are defined as discrete lighting control devices that can perform their
designed function without the requirement of being connected to additional devices.
Common devices that may fall under the category of "Self-contained” include:
- Self-contained Automatic Daylighting Controls
- Line powered Occupancy Sensors
- Line power Vacancy Sensors
