Emergency Lights | Buy UL listed emergency lighting
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.
Cold Weather emergency lights & exit signs
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.
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
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.
What is Title 20?
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
Rechargeable batteries are batteries that can be recharged and reused multiple times. They are more environmentally friendly and cost-effective than disposable batteries. One of the most common types of rechargeable batteries is the 12 volt battery, which is often used in backup power supplies, LED lights, CCTV cameras, and other devices that require a steady and reliable power source.
12 volt rechargeable batteries come in different sizes, capacities, and chemistries. Some of the most popular chemistries are sealed lead acid (SLA), lithium ion (Li-ion), and lithium iron phosphate (LiFePO4). Each chemistry has its own advantages and disadvantages, such as weight, lifespan, performance, and safety. For example, SLA batteries are heavy and have a short cycle life, but they are cheap and easy to maintain. Li-ion batteries are light and have a high energy density, but they are expensive and prone to overheating. LiFePO4 batteries are stable and have a long cycle life, but they are costly and have a lower voltage than other lithium batteries.
