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.
Sealed Lead Acid (SLA)
Sealed lead acid batteries are sometimes referred to as VRLA (valve regulated lead acid) and there are two primary types AGM and Gel. We offer both AGM and Gel batteries, each has its advantages over the other depending on the specific application. SLA batteries usually last between 3 to 5 years with typical usage. The optimum operating temperature for the lead-acid battery is 25°C (77°F). Elevated temperature reduces longevity. As a guideline, every 8°C (15°F) rise in temperature cuts the battery life in half.
6 volt rechargeable batteries are a type of battery that can be recharged and used multiple times. They are commonly used for devices that require a low voltage and a high current, such as game feeders, lanterns, emergency lights, and electric signs. 6 volt rechargeable batteries have several advantages over disposable batteries, such as saving money, reducing waste, and preventing short-circuiting.
There are different types of 6 volt rechargeable batteries, such as Sealed Lead Acid (SLA)
, lithium iron phosphate (LiFePO4), nickel metal hydride (NiMH) and Nickel-Cadmium (NiCD)
. Each type has its own characteristics, such as capacity, cycle life, weight, and price. For example, SLA batteries are cheap and durable, but heavy and bulky. LiFePO4 batteries are lightweight and long-lasting, but expensive and sensitive to overcharging. NiMH batteries are eco-friendly and high-performance, but prone to self-discharge and memory effect. Depending on the application and preference, users can choose the best type of 6 volt rechargeable battery for their needs.
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.
Remote capable exit signs or emergency lights allow the unit to add additional lighting with remote light heads without adding additional fixtures.
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.
Buy America Compliant (BAA)
Products displaying an 'Assembled in the USA' label will contain a percentage of imported components but will be physically assembled in America and are compliant with the Buy American Act (BAA). The FTC states that Assembled in America products must have undergone a significant transformation on American soil.
Products with internal heater option allow the units and batteries to operate properly at temperatures down to -50°C.
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.
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.
