Thanks, I wasn't sure if 360 turns is enough. Today I tried changing resistors, ( I need to get myself a rheostat or two) and it's strange - I tested the light with modified CFL and 64 leds and both bulbs need different values. The rheostat would solve the problem of adjusting the circuit for a specific bulb. My goal is to set it up in a box with a regular 110v outlet and a switch so I can connect a night lamp with a modified bulb.

@all
I am using the lidmotor's circuit with 3 and 13 turns on the primary, But I am thinking this my be wrong for this toroid. I will try 5 and 5 and maybe other combinations. If you guys know what influence the number of each turns has on the circuit, please post.

Good luck with you tests.
