Hi I am trying to build an Emergency Lamp and got this schematic from the web.
**broken link removed**
The problem is I think the zener diode is not producing enough current on its breakdown state to turn on the transistor. I tried removing the resistor R2 but still won't work. Can you help me how to make this work?
