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.
The main housing of these exit signs and emergency lights is painted black or made from a black thermoplastic.
Federally approved high temperature 4.8 Volt exit sign and emergency lighting NiCd batteries. A 4.8 Volt NiCd has four AA, AAA, C, Sub-C, D or F cells in a battery pack that can come in a variety of configurations. Most common are cube, row and stick configurations.
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.
Recessed mounted exit signs or emergency lights offer a low-profile installation by hiding the housing, which includes the electrical components of the exit sign in the ceiling.
This feature may be added to many exit sign and emergency light fixtures, the SDT feature prolongs battery life, and reduced man hours required OSHA tests. Self testing diagnostic automatically executes a 15 minute test every 30 days and runs a 90 minutes test once per year. The major reasons batteries typically fail is because they remain dormant for long periods of time. With the SDT feature automatically simulates a full discharge and full recharge to keep the batteries in peak performance. If any problems arise during this testing process it will report them through the user interface. This benefit drastically reduces man hours required by OSHA to manually perform the tests.
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.
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.
Lithium Iron Phosphate (LFP)
The lithium iron phosphate battery or LFP battery, is a type of lithium-ion battery using lithium iron phosphate as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. The energy density of LiFePO? is lower than that of lithium cobalt oxide, and also has a lower operating voltage. The charge-discharge profiles of LFP cells are typically very flat. The main drawback of LiFePO? is its low electrical conductivity. Therefore, all the LiFePO? cathodes under consideration are actually LiFePO?/C. Because of low cost, low toxicity, well-defined performance, long-term stability, etc. LiFePO? is finding a number of roles in vehicle use, utility scale stationary applications, and backup power. LFP batteries are cobalt-free.
