The I-320 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 theevent of a power failure, the I-320 switches to the emergency mode and operates one of the existing lamps for 90 minutes. The unit contains a battery, charger, and inverter circuit in a single can, and can be mounted in the wireway or on top of the fixture. The I-320 can be used with most 2′-4′ T8 lamps and 2′-4′ 14W to 54W T5 lamps, with an initial output of up to 1350 Initial Lumens for one lamp. The I-320 utilizes AC output to ensure compatibility with new lamp technologies, and features lamp selectorleads for optimizing light output for the designated lamp type. The I-320 delivers high performance in a slim design, and is ideal for use in fixtures where ballast compartment space is limited. The I-320 is suitable for use in damp locations.
