Emergency Lights, Nickel Metal Hydride (NiMH), Title 20, NEMA4X Rated Products (4 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.

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.

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:
