Product Description

The I-32 Fluorescent Emergency Ballast from IOTA Engineering allows the same fixture to be used for both normal and emergency operation. In the event of a power failure, the I-32 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. The I-32 can be used with most 2'-4' T8 thru T12 and 28W T5 lamps, with an initial output of up to 500 lumens for one lamp, and features lamp selector leads for optimizing light output for designated lamp types. The unit can be mounted in the wireway or on top of the fixture. The I-32 delivers high performance in a slim design and is ideal for use in fixtures where ballast compartment space is limited. The I-32 is UL Listed for use in enclosed and gasketed fixtures.
