Ok, i just tested the new 5 volt-2.4 amp usb charger on the circuit as is.
It is drawing 150 milliamps at 5.25 volts or .788 watts, the brightness is ok, not at the level it was before,
so will have to make some alterations to the setup.
One thing that is interesting, the neon is still lighting up fairly bright across the transistor collector/emitter,
even using this 5 volt input.
I wonder if my diodes are ok, or since i have so many turns on my coil, maybe i am getting some
high voltage induction from the on phase of the input pulse, or i need to use a full wave bridge.

Yes, the neon when is lit (placed across collector-emitter) indicates the peak (voltage spike)
amplitudes are higher than the neon's trigger voltage hence it limits the spikes to that level. 
To utilize the higher than the neon trigger level spike amplitudes and steer them also to the puffer capacitor,
at least a 500-600V rated switching device is needed and then you can omit the neon.
IF your neon has a trigger level of say anywhere between 70-100 V, then you could try two of them in series
and see whether they are still lit. Their trigger levels add so the two of them are still able to protect your
present 230 V  rated transistor.
Of course you may use a full wave bridge made from the fast MUR or other fast switching diodes.
From the 5V input supply your base resistor (220 Ohm) may need another value, perhaps a 1 kOhm
trimmer potmeter with a series 100 Ohm would be good to use and vary (like in magnetman's schema).

Hi all, Hi gyula, thanks for the helpful information.
Yesterday, i tried a bigger capacitor, that did not turn off the neon, then tried a full wave bridge, that did not turn off neon either.
Your 2 neon in series worked, they are no longer lighting.
Only problem now is, the 4 gutted led bulbs brightness at the 5.25 volt input, is not sufficient.
I will have to make another bifilar coil using less turns.

Hi,

Well, there are many makes of the LED assemblies, and it is surely hard to find the ones having the most efficient inner drive circuits with or without.  Magnetman wrote about his experiences.
I assume you mean the gutted LED bulbs brightness was not as sufficient by "default" as the Eco types were?

Has anyone made my circuit EXACTLY as I have posted  here.  All was posted as OPEN SOURCE information.  Presently using a 5 volt USB wall adapter I show 5.7845 watts powering  8 seven watt 12 volt bulbs. That's 56 watts and all 8 bulbs burn brightly.   I would like to know if anyone is following my specs exactly as posted.

Hi gyula, the gutted led bulbs i'm using now are fine, it's just when using the 5 volt input with this coil, is not sufficient.
So i made made a new coil earlier today, will be testing soon.
Hi magnetman, i do not have any 12 volt bulbs to test at the moment, i have a ton of 120 volt led bulbs though.
Plus the fact i could not get the SCR to fire properly, though since i do not know what frequency or anything about how yours is functioning, what are we to compare it with.
The oscillator itself should not matter, unless yours is operating with super efficiency.
So for now, I'm working on at least getting an oscillator running on the 5 volt input and getting good light output, i can always try the SCR again or get the one you are using, maybe that's what is needed.

 Hi Sky Watcher,
I tried many times to get things going using 120 volt led bulbs.  My basement is absolutely full of them.  Some worked but very dim some pulsed and others did not work at all. Next my attention shifted to the 12 volt led bulbs.
Some worked by spinning a magnet near the air core coil to start.  The 12 volt bulbs I am using now burn brightly without using a magnet spin. They are cheaply made but very inexpensive.  All have aluminum heat fins but run cold to the touch in my setup.  Its very hard to tell the brightness level powered from either 12 volts verses the 5 volt USB wall charger.  Both look as bright.  Made in warm white and bright white.  I like the bright white.

Hi magnetman, ok, thanks for the information.
The results are coming along with the 5 volt input, i'm just removing coil winds until i find the brightness, power level that is best.
I'm using 4 identical, gutted led bulbs at the moment and it was very easy to convert them to just direct led drive, without the inner circuitry that is, took around 5 minutes per bulb.
If these bulbs don't work out, then i will look into getting the 12 volt bulbs.

Hi all, ok, i was able to tweak the circuit to get equal brightness with the 5 volt usb charger.
Using 4.72 volts at .8 amps or 3.7 watts, the older model 6 watt ecosmart, non-modified led bulbs are brighter and drawing less power than the gutted led bulbs.
The older model ecosmart bulbs are somehow lower voltage bulbs, the puffer capacitor is sitting at around 46 volts, whereas with the gutted led bulbs, it sits around 96 volts.
So, this leads me to believe that the 12 volt led bulbs will probably work well with this type of flyback circuit, just as you are showing magnetman.
Will have to get at least 4 of those.

You want to use these lamps and they are selling from a USA dealer.      http://www.ebay.com/itm/New-5-x-12V-High-Power-LED-Lamp-Bulb-E27-E26-7W-White-Light-Energy-Saving-/252019335458?hash=item3aad85e122:g:JMAAAOSwjVVVsILY

Hi magnetman, thanks for the information.
I ordered these warm white ones just now, i like the warmer color.

One thing i have to be sure not to do when i get these, is not have the capacitor charged when i connect the bulbs, that is without some type of scr switch in place, because last night i popped the last low voltage bulb i had been using for a night light.  :(
I wonder what the actual lumens rating is on these bulbs at 12 volts direct, because the data on the website seems like it was taken from different sources and contradictory.

I spent 3 years experimenting with this circuit ...  I have at the least 200 pounds of experimental parts that I have to sell now. Some are brand new that were never used.

Did you try self-looped circuit already? It shouldn't be difficult with respect to performance given: instead of powering LED bulbs just try to power that USB wall adapter... ;-) BTW The neon bulb is sensitive to light - its ignition voltage strongly depends on illumination (photoeffect).

USB input to setup  5.03 volts at 1.15 amps. (5.7845 watts)  Output from setup capacitor to bulbs  5.93 volts at 1.03 amps  (6.1079 watts)  I checked this many times and came up to the same results. A plus .3234 watts unknown ?? power.

Such a result looks more realistic for me. The alleged surplus of 0.3234 watts will be probably measurement error of your wattmeter. These devices are calibrated for flat voltage source or harmonic sinus wave output - which your oscillator producing peaks trimmed with neon lamps definitely doesn't generate. Not to say, your wattmeter is designed for grid input - its precision will go down at low voltages.

I do appreciate your selflessness very much! But I don't understand the remark "DIAMETRIC RING MAGNET" in your diagram. Where this magnet should be located?
The main coil mentioned at your description is air core one. And I don't understand the meaning "INNER COIL / OUTER COIL" at your diagram.
I redrew your scheme for reference - please see bellow. Thank you for your explanation in advance!

 Hi Sky Watcher,
I would measure the voltage directly on the insides of the powered empty bulb sockets before installing the bulbs to be sure there won't be a burnout after the bulbs are installed.   If you can fill a room with light continuously using 5 + watts (8 lit 7 watt bulbs) that's good enough for me.  Otherwise you would have to invest in a lux meter and test the brightness which by the way will decay if you use a battery as a power source.   The voltage must be constant that's why I am using the LARGER 5 volt USB wall adapter as power.
Small units have thermal shutdown problems and cutoff quickly.

Hi all, Hi magnetman, ok thanks for the tip.
Yes, checking voltage at bulb bases would be the best way to prevent them going poof.
Have you blown any bulbs yet by making this same mistake i did, 3 times already.
I was researching the bulbs you are using and ones i will be getting and apparently, one guy that sells them, says the 7 watt version is around 600 lumens when using direct 12 volt battery power.
And he does mention the normal dc power will degrade them faster.
The circuits we are using, they should last longer because the lack of heat.
What kind of heat are you feeling on yours, have you run them long enough to see if they get warm.

Hi,

Yes, checking the voltage level at bulb bases is very good to 'prevent them going puf' but
only in case you feed the LEDs directly from your puffer capacitor. If you have a working
switching device like a thyristor magnetman uses to feed the bulbs from the puffer capacitor,
then your meter may get fooled.  This is because the thyristor choppes up the DC voltage coming
from the puffer capacitor (C1 in his schematic) and very likely a sawtooth-like wave shape could be
measured across the bulbs by a scope in this case.  Magnetman reported he measured
3.54 V DC across the 12 V lamps with a DMM, see this:

   I took out one of my eight bulbs and measured 3.54 volts inside the lamp socket? ???   All lamps
were lit during this test.  My room looks like  bright  daylight at 12 o'clock midnight with all lamps lit.

 
Maybe it is a bad idea to connect a second capacitor, C2 across the LEDs to smooth out the sawtooth
waves from his present operation point of view and the brightness or input power draw changes
too much, I do not know.  This should be tested and decide accordingly. I suggested the use of
capacitor C2 to filter the chopped-up waveform and make it DMM 'friendly',

  After putting one bulb in a refrigerator for a while I  test ran the bulb for 10 mjnutes using the large USB  power source.  The bulb was cold to the touch. I never blew a 120 volt led but did get one of my CORN BULBS to light up on its own.  Nothing else however would work.  That's when I switched to 12 then 5 volts and things got  much better.   http://www.mouser.com/ProductDetail/STMicroelectronics/BTW69-1200N/?qs=%2fha2pyFadujfF8w4qfSV3KjM7tz3jvhm3XoAXzHXxd9%2fzgbqzI5K1A%3d%3d
