The Iota I-26-EM-A is a Compact Fluorescent Emergency Ballast that allows your current fixture to be both normal and emergency lighting. It will operate with magnetic ballasts and 2 pin 18W-26W CFL lamps, storing up electricity in its high quality battery so that during the event of a power failure one lamp can continue to operate for 90 minutes.
It is now a legal requirement for many commercial, institutional or industrial buildings to have emergency fixtures. This back-up battery transformer can allow your current lighting to switch to emergency mode during a power outage, and will power one lamp at up to 650 Initial Lumens for 90 minutes. Plenty enough time for you or anyone in the area to make their way to an exit safely. It comes with a test switch and charge indicator kit, and has the battery, charger, and inverter circuit all in one can. It is designed in a way so that it can be mounted either on the fixture or in the ceiling adjacent to it. Also provided is a 3/8 inch flex to assist in wiring it to the fixture or ballast compartment.
