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.

Batteries placed in cold environments can eventually fail or rupture. If your emergency lights or exit signs will be installed in temperatures below 20° F (-6° C), you may want to consider a cold weather option. Cold weather lights include a thermostatic battery heater which maintains the battery strength and lifespan in temperatures between -4° F (-20° C) and -40° F (-40° C) depending on the model you choose.

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.

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.

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.

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.
