Emergency Lights, Cold Weather, 12 Volt, Battery Backup, Gray, Surface/Wall Mount Products (15 items)

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.

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.

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.
