9 Volt Bolt (Flashlight Conversion)



About: "May the good belong to all the people in the world. May the rulers go by the path of justice. May the best of men and their source always prove to be a blessing. May all the world rejoice in happiness. ...

I had a flashlight containing 4 leds.

It worked on four button cells of 1 volt each.

Each white led can take upto 3 volts. So 4 leds could take upto 12 volts.

I decided to remove the four button cells and add a 9 volt battery to the flashlight.


So i soldered a battery cap to the four leds.

(Black wire of the battery cap to the negative of the LED and red wire to the positive of the LED assembly. )


Final result was a powerful flashlight!

Potential 12 volt leds, earlier running on 4 volts, now running on 9 volts!

This conversion can be done on any flashlight with more than 3 LEDs.

Happy with the outcome! ;-)
