I42 Emergency Ballast

Emergency Ballast for 4-Pin LED Retrofit (TLED) and Compact Fluorescent Luminaires

By IOTA

  • Overview
  • Specifications
The I42 from IOTA Engineering is a UL Listed fluorescent emergency ballast that allows the same fixture to be used for both normal and emergency operation. In the event of a power failure, the I42 switches to the emergency mode and operates one or two of the existing lamps for 90 minutes. The unit contains a battery, charger, and inverter circuit in a single can. The I42 utilizes AC output to ensure compatibility with new lamp technologies, and features lamp selector leads for optimizing light output for designated lamp types.
