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.
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.
A damp location is an interior location normally subject to dampness or condensation, or an exterior location protected from weather and not subject to saturation with water. Damp locations include over bathtubs, indoor pools, covered porches, and like locations.
Wet Location emergency lights and exit signs are weatherproof and designed to be used in outdoor environments, as well as indoor locations that are exposed to water and moisture. Wet location emergency lights and exit signs are extremely durable and long-lasting.
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.
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.
Remote heads are lights used in conjunction with a remote capable emergency lights or exit sign. Essentially, remote emergency light heads offer more than one backup lighting location, without having to add additional lighting systems. The result is a flexible system with low cost and maintenance.
Outdoor lighting is lighting used to illuminate the areas, where there are no roofs, i.e., outdoor areas. Outdoor lights are able to be in the elements of including rain and cold weather.
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.
Commercial lighting is lighting used for commercial spaces such as offices, stores, institutions, hospitals and government buildings, essentially those spaces that are not residential, industrial or for manufacturing.
