Acuity Brands Emergency Ballast - Two Lamp, Dual Flexi

The I42 A fluorescent emergency ballast allows the same fixture to be used for both normal and emergency operation. In the event of a power failure, the I42 A 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 A can be used with most 10W-42W twin, triple, quad tube, 2D and Straight 4-pin compact fluorescent lamps and 18W-36W long compacts, with a total initial output of up to 650 lumens for one or two lamps. The I42 A utilizes AC output to ensure compatibility with new lamp technologies, and features lamp selector leads for optimizing light output for designated lamp types. The I42 A includes dual flexible metal conduit for running wiring to the fixture and to test components for installation within a separate junction box (not included.)
