Oscillator Powering 6 Modified Led bulbs

[SkyWatcher123]

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?

If the neon bulbs are necessary, is it this type found here on http://m.ebay.com/itm/20Pcs-5x10mm-Orange-Light-Neon-Bulb-Indicator-Lamp-100V-220V-w-Resistor-M2524-QL-/182047562531?nav=SEARCH

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.
