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 black or made from a black 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.
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
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.
New York City Approved
New York City has very specific codes regarding emergency lighting and signage. In short New York City approved exit signs must be Red 8 inch tall letters with a 1 inch stroke (line thickness) as opposed to 6 inch tall with a 3/4 inch stroke in typical exit signs.
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.
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.
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.
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
