Bodine Electric B33AK Fluorescent Emergency Ballast

The Bodine Electric B33AK Fluorescent Emergency Ballast is a compact emergency ballast designed to retrofit fluorescent fixtures for independent illumination during power outages. It supports fluorescent loads in the 36–55W range and accepts input voltages of 120V or 277V at 60 Hz, delivering 280 mA to the emergency lighting circuit. This model, part of Bodine's line of fluorescent emergency ballasts, operates in conjunction with the fixture's normal ballast to provide emergency operation without external power. In the event of a power failure, the ballast switches to emergency mode to power the designated lamps, aiding safe evacuation and wayfinding. Common applications include commercial and institutional interiors such as offices, classrooms, hallways, and stairwells where reliable emergency lighting is required. The AK designation identifies this variant within the B33 family; users should verify compatibility with their specific fixture and ballast arrangement to ensure correct operation and lamp compatibility.
