See: http://www.youtube.com/watch?v=D_vSAP3nJcU&feature=youtu.be&a My "run a CCFL on 1 battery and a 2 transistor inverter" experiment was a success! For this project, I used one inverter transformer and a CCFL (cold-cathode fluorescent lamp) from an old LCD monitor. The 2 transistors are NPN, type BD737 from a (very old) old cassette player. The 2 resistors are 82 Ohm (grey-red-black) and 1/4th Watt. I think almost any NPN transistor in this package should do the job. It has a BCE pin-out. On a full 9 volt battery, I got around 600-750Volt but the battery was draining fast.
