I am updating the previous video. I found that there were a couple simple things that are improvements. And the trigger coil did absolutely nothing. I also decreased the primary to 25 turns which lowers amps and increases voltage. The small signal transistor is running at only half its power rating now. I think this lamp should just be a bright lamp and run off 12 volts. But, with the transistor type I am using the circuit will light the CFL at just 2 volts. As you increase voltage the lamp brigthens. Or, as the voltage drops the lamp still works. Great for camping, emergencies, cabins, boats....
