Emergency Lights, AC Only, Commercial, Ceiling Mount, Nickel Metal Hydride (NiMH), Recessed Mount Products (2 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.

AC only exit signs do not include a battery backup or charging circuitry and are for installation and use only where emergency power is supplied from a remote or secondary AC power supply.

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.

These products can be hung from the ceiling. Many exit signs come with the ceiling mounting canopy included.

A nickel metal hydride battery, abbreviated NiMH or Ni–MH, is a type of rechargeable battery. A NiMH battery can have two to three times the capacity of an equivalent size NiCd, and its energy density can approach that of a lithium-ion battery.

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.
