This T8-T12 emergency transformer will power 1 bulb (compact or linear fluorescent types) for up to 90 minutes while grandma, sparky and the kids 'get the heck out of Dodge.' During normal hours, when the AC is flowing, this damp location battery pack will draw almost no power as it trickle-charges the battery, ready to spring into action at a moments notice.
