Run fluorescent lamp by 1.5v AAA battery

By this circuit you can run a 4w fluorescence lamp by 1.5v.

I test it for running 20w fluorescence lamp, it run but give low brightness .

The transistor can be C2500 or 2N3055.

You can find the chock coil from an old mobile charger or old camera or electric zapper.

NOTE: the output voltage is up to 180v so is dangerous.

Parts list:
Transistor C2500
Resistor 270 ohm
Chock coil of old camera or electric zapper or mobile charger
Battery 1.5v AAA or AA
LED
