Hi all, i've made some changes with my setup.
I removed all the 24awg. wire from that big core and am now using a single ferrite tube core, with only one layer of bifilar, 24awg. magnet wire.
This way, i can go back to using the 12 volt computer power supply.
It works very good and frequency is much higher.
I also added another separate full circuit, with same type of core and coil, using a separate PNP transistor, also off the same power supply and switch.
I did this for a couple of reasons, one was to get even more light output, while staying with 4 modified 120 volt led bulbs per circuit.
Second reason is because i just picked up another 4 meijer led bulbs and they are not quite the same as the previous ones, so the led bulb loads did not balance when in parallel.
So another driver circuit is a good solution i feel.
Also, these circuits are more efficient than all i have tried so far, i'm sure the high frequency is part of the reason.
Not quite finished yet, i have to run a separate line to the ceiling. to the other set of 4 led bulbs.
When i finish, i will post some pics and circuit drawing.
peace love light

Where are you buying the ferrite tubes?  I have miles of 24 gauge  wire and am very interested in your doings. Love to see your circuit and photos.

Hi magnetman, i had previously bought the ferrite tubes at a place called american science and surplus.
They are just over an inch in length, i just super glued 4 of them together to make the core.

it sounds like he is using ferrite rings, try it with some of the high impermeability ones on the market like Farnell ect.

good luck. AG

Yes brothergrey, they are ferrite rings they use for noise suppression.
Not sure what kind of permeability they have, probably not much, though they are working well.
I'm at the moment, hooking up the line to the new set of 4 led bulbs. 8)

oh and the coil is wrapped around the ferrite tube, normal solenoid coil style.

Here is a thought:  You can insert a ferrite rod into one end of your ferrite tube and by working it back and forth you can fine tune your circuit.  Glue it in place when you find the perfect sweet spot where best light output occurs with lowest current flow.   Also need to know -- I have a ceramic ferrite rod magnet that is 5 1/4 inch long and 3/4 inch in diameter.  Can a ceramic magnet be used in a ferrite called for situation or would the magnetic effect interfere in a joule thief application?

Hi all, Hi magnetman, that's a good idea, if i had a ferrite rod that fit, i would try it for sure.
Maybe if you demagnetized the ceramic magnet, though somehow i think it still wouldn't work well, because it might want to become polarized again.
I finished the new setup, it is very bright, with all 8 bulbs burning.
Though it is using 7.6 watts, there is quite a lot of illumination being output for that wattage input.
Here is the circuit drawing and a pic, just to give an idea.
I also just realized the 4 newer led bulbs i got, they are showing around 55 volts on buffer capacitor, so that means those bulbs had a step down circuit inside them, where as the other bulbs show around 96 volts.
This would explain why they were not load balancing in parallel, with the single oscillator circuit.

Hi SkyWatcher 123,

I have two monster ferrite rings that are  5 inches in diameter and 2 inches thick. Looks like a huge donut Never found a use for them. Very heavy. Do you think one might make a good coil if I put the same amount of wire turns with 24 gauge wire you used on your 12 volt setup?
I can easily band saw slit the ring and wind turns through the slit.  The nice thing about this if it works at all is the fact that I can pull/push another small section of ferrite in and out of it and fine tune for maximum effect?

Hello Skywatcher,

Please can you show how you modify the bulbs without destroying it. The Cfls we have here can be easily unscrewed in order to access the circuit. But the leds bulbs here are completely sealed. Can you post a link on ebay where I can buy EXACTLY the led bulbs you are using? Can you also post a picture of the internal modified bulb, with the output connected directly to the bulb?

Also, can your circuit run directly from a battery with the same impressive performance as the computer power supply? Finally, speaking of your ferrite tube, does size matter?

Hi magnetman, that might work ok and it might even be ok if you don't cut a slit in the core.
Though i have found that an open core seems best for these flyback radiant spikes.

Hi Naija, If i have trouble getting the bulb diffuser off, i use a heat gun, that softens the glue and then can be easily pried off with a flat screwdriver.
The bulbs i'm using are from the Meijer store, it's a 120 volt led bulb, though some as said, vary as to what the actual driving voltage is, of the led board inside, but that's ok, because the circuit can be tweaked to compensate for that.
Every led bulb i have, has a dual power pin on the led circuit board, i use 24awg. telephone wire, actually might be 20 or 22 gauge, to slide into that dual pin and then one wire is press connected into the removable bottom pin of the bulb.
The other wire is ran outside the bulb, if you have to drill a small hole in the plastic, do so, then i solder that to the upper part of the bulb screw power connection.
Yes, a battery will work fine, though depending on amp draw, battery capacity will be based upon that.
As far as the ferrite tube core, i think this is working well, because the winding length is not too long, so as to keep frequency up at the lower 12 volts and allow a nice amperage to flow per pulse.
Otherwise, if the windings get too long, you have to go to a higher input voltage to get the brightness desired and frequency up.
Here is a couple close up pics of one of the led bulbs in one set of 4.

Thank you Skywatcher for your quick response. One last question though, is there a replacement for the neon bulbs? Since it's job is to protect the transistor, is there something else like diode that can execute the same job?

Hi Naija, i don't think a diode will work, because then that will divert all the current away from where we want it go, that being to the buffer capacitor and led bulb.
The neon activates at a certain higher voltage, so any excess overflow voltage/current that might exist and is not being absorbed into where we want it go, does not damage transistor, as you pointed out.
I'm not sure what component can serve the same kind of protective function.
It might be ok though, as with this particular coil length and core, it is no longer lighting a single neon while in operation, which means it is not creating an excess abundance of voltage, which if it were, might not be effectively used by our led bulb loads.
Also, if you choose a high voltage transistor, then you should be ok.

The voltage of any neon you get, will be dependent upon which transistor you are using, if you are using a 100 volt transistor, then a 100 volt neon would be good.
So, a higher voltage transistor would be best in these types of radiant spike circuits and in case you forget to connect the load for some reason, high voltage would be present across the transistor.
