This circuit is permanently plugged into a mains socket and NI-CD batteries are trickle-charged. When a power outage occurs, the lamp automatically illuminates. Instead of illuminating a lamp, an alarm sounder can be chosen. When power supply is restored, the lamp or the alarm is switched-off.

Wind L1 by T1. You will need an AM antenna rod that is about 60mm (2.5 inches) long to wind T1 by L1 on. T1 byL1 are wound on the same core. Shrink a layer of heatshrink over the core to insulate it.

This project is a mini lantern-style, electronically regulated, super bright rechargeable flashlight. It outputs about 120 lumen (slightly more than a 6D cell Maglite) . Its also much lighter in weight than a Maglite or a 6V lantern and can provide about 2 hours of constant brigtness illumination.
