Nick:

The TIP 3055 is what we used in the Jeanna's Circuit light.  That circuit puts out between 750 and 1,000 volts and will light up a bunch of stuff.  But again, the input here was just the little single AA battery.

Laser's circuit is amazing.  I may have to try this one also.

Nick,

I am using the warm CFLs throughout my house now.  They cost 99 cents each and I can't tell the difference between them and an incandescent.  The light is a warm yellowish light.  I forgot that you are trying to light bulbs wirelessly.  You may do better with a Tesla Coil circuit.  I use the TIP 3055 for that with a capacitor, resistor in the circuit.  I can light 60 watts of florescents from about 3 feet off a well charged 12 volt.  Not sure why your transistors are heating up.  Maybe you could show us your circuit and we could help.

You realize incandescents are more like toasters.  Most of the power is heat when they are bright.  I understand that the power is free and you don't care.  You may want to try the warm white CFLs just out of curiosity.

 No doubt the warm white Cfls are easier on the eyes, I do have several of those also. But the ungutted ones can't be dimmed,   At a dollar or two they are hard to beat for now. I don't like them in the bathroom because when I see myself in the mirror, I can see the difference on how they make you look, not as nice, like you've  got hepatitis, as they are yellower, and less golden.
It's also a matter of finding just the right bulb, as they are all different, so are all the Led bulb types.
 
  I'm working on a 3 inch long ferrite coil similar to the LS 3.0 ringer, but smaller.  I tried it with the Tip 31, but haven't got it running yet. 'll know more by tomorrow.
  If you have a video or description of your set up lighting 60 watts of Cfls,  let me know where to look, or upload a link if you can.

Nick,

Here is a video of the Tesla coil (SEC exciter) powering multiple florescents.   I moved away from this and to the more practical lighting that can be achieved with the blocking oscillator direct connected to bulbs.  It does open the mind when you see power conveyed through thin air.

I made one of these lamps using a toilet paper roll, it's only 3-3/4 inches long at 1-1/2 inches diameter. I had some left over 30awg magnet wire, enough to wind two secondary layers of 250 turns. The primary is 16 turns of 22awg. Works great so far, I've been able to get down to using 502ma with a modified 13watt CFL at maybe 60% brightness. If I had more 30awg, I would add another layer of 250 and see how bright I can get the CFL.

I'm gonna try using heavier wire on the primary, and possibly try building the larger 5,0 version.
Not easy winding this sucker, all manual, difficult to keep the 30awg wire even on the roll, and especially after using clear tape to insulate after the first layer. I Should have used colored tape so I didn't see through to the first layer of red magnet wire.

Anyway, thanks for sharing this info, it was fun building, and if I add more layers, I keep you posted on progress.

Wind baby wind!!!
