Fluorescent Light.
How to build a 4-Watts Fluorescent light using a disposable camera, powered by one 1.5 Volts battery. (5/29/2006)
A flash circuit have a hi-voltage oscillator and transformer. It generates about 300 Volts AC & DC. The circuit inside a disposable camera with flash can be used for many other applications, this time, I built a 4W fluorescent light powered by one 1.5 Volts battery.

After removing the cardboard, is possible to remove the battery and the film. I opened the camera with extreme care because it contains lethal voltages. Also, I saved the lens because I can build a microscope with it.




Here is the modification that need to be done to drive a Fluorescent light:





Here is the schematic for the 1.5 Volts 4-Watts Fluorescent light:
