Hmmm, no idea.  If the bulbs are this hard to find then this is a bad idea. 

If you hook the bulb up to straight twelve volt, does it flash or blink at about 1x second or so.  That's what mine do on straight 12 vdc.  Once you hook up through a transformer the light is nice and you can dim with a pot.  What is the code on the bulb's base?

I did some more testing.  Rather than see how low I could go with amps, I was looking at how bright I could go.

At 12 volt the bulb runs at .6 watts
24 volts the  bulb runs at 2.8 watts and as bright as mains power
30 volts at 4.2 watts (over bulb rating)

Different transformers will run at different rates.  This was using my best transformer which is another subject.  It is a snap on choke wound with 200 turns 30 awg and 20 turns 26 awg.  Hz varies from 160 - 800
Placing one or two magnets anywhere around the transformer causes amp draw to go up with no apparent brightness increase.  Hz goes down with magnets on the transformer.  You can hear the frequency decrease as you draw a magnet near the transformer core.

Here is an example of a LED bulb at Home Depot for $14.97.  This one will work nicely.  It is non-dimmable.  I am using this one.  I am also attaching another schematic of how to wire it up.  Its the same as I have posted but maybe explains it another way.  I think the significance is the low amp draw you can obtain using this method.  No ringing, multiple bulbs, easy start, no heat.  Can exceed rated brightness or be turned down to a candle light.  You can run this off a capacitor, direct dc from solar, or battery.

Here's another thing I want to share.  With the larger transformers (450 ma and up) you can run the LEDs from the yellow leads only.  Use a variable resistor to adjust amount of light.  Rectify the other transformer outputs to higher voltage DC (these are the heavier black leads).  I ran my 35v 4700uf capacitor right up to 35 volts.  Its not going to self run, but you might find the voltage boost useful for charging 1.5-12 volt batteries or you can run some other circuit needing AC or DC.  This set of windings is completely separate from the running circuit.
This is the funnest, simplest and most useful circuit I have played with since the Aircore Joule Ringer.

 ;D  Woo Hoo ~ Funny how things work when you get the right parts.  Picked up the last 2 bulbs from my local Walmart today (GE bulb Lynxsteam posted above) and it works like a charm.  Only tried one of the circuits posted and fired right off.  Uses about 13 to 14 ma on the transformer I started with.  Will conduct measurements with other transformers I have on hand and the various circuits to try and get the best light at least current possible.
 
Also, on a whim, I picked up a 2 pack of LED Super Bright Night Light replacement bulbs by Meridian and they work as well.  Rated at 0.6w and draw 150 micro amps with the same setup listed above.  This bulb works in parallel with the GE bulb or alone.  The bulb is not bright at that current, but it does light up.
 
Going to have some fun playing with this ~ thanks again Lynxsteam.

I remember you were the first to replicate the early Joule lamp and you did it better than I did.  I look forward to what you may find out with your experiments.

Its too bad these bulbs are so uncommon and so expensive.  However, they are a very neat way for me to convert the wind energy from my Turbines to useable power.  A small solar panel and small wind turbine would more than power 6 of these 24/7.  My small 24" wind turbine puts out up to 2 amps, and in average 8-10 mph winds 100-200 ma

The output from the unused secondary is high voltage up to 67 volts rectified DC, but very little in amps.  I was charging a 9 volt battery and seeing 4 ma.  That's OK.
Still I think for the price of a small ready made transformer this is a very efficient way to light LED bulbs.  I'd be curious how this compares to just buying 12 volt LED bulbs.  I bet Lidmotor knows the answer to that.

Hi Guys,

I just play with my homemade LED Bulb 220VAC 3Watt (I bought driver & HPL Led and I assemble on the E-27 Fittint) today. It consist of 3 LED Driver & 3 High Power Led. I try Lynx schematic using standart transformer and it work. Then I try directly connect my LED to various DC voltage and it work great. Here couple of my pict. When I directly connect to grid it draw 18 mA, when connect to DC 12 V it draw 8.1 mA, connect to 24VDC it draw 29.1 mA and connect to 36VDC it draw 35.3 mA.

Keep experiments
Djoko

Here's a video showing the two 3 watt bulbs running off the yellow of the transformer at 12 volts and .36 -.5 watts each.  The two heavier black leads are run to a full wave bridge rectifier and to the volt meter showing anywhere from 30 -70 vdc depending on the voltage and brightness of the bulbs.  The output from the bridge rectifier will trickle charge batteries.  Charging batteries doesn't seem to affect bulb brightness. Its not free energy but it is a very simple and efficient circuit.

@Lynxstream,
 
                 Is the battery gaining?

hAVE YOU TRIED WITH AT LEAST 10 220 V AC LED LAMPS  then its a winner if we can use less amps   for solar lighting     thanks

@Lynxstream,
 
                 Is the battery gaining?

No, wouldn't that be great if it did!  The significance for me with this circuit is how simple it is and how well suited it is for 12 or 24 volt power which is what I am dealing with.  I build wind turbines that charge 12-24 volt batteries.  Trying to run lights off a typical inverter or even straight 12 volts is an amp killer.  None of this matters when a Kw costs 20 cents.  But it does matter to people that don't have what we have.

What I see is anywhere from 5-80 ma to power these 3 watt bulbs at varying brightness. 

There is still more to learn from this circuit.  It seems that high frequency is a help in fooling LEDs into thinking they are getting rated power when it may be much less as measured by volts and amps.  60  or 50 hz has to do with how power plants were devised over a hundred years ago.  Exploring other frequencies is a very interesting endeavor.  The results in the lightbox with the Lynx Joule Lamp showed very high efficacy at high frequency.

I am hoping we can get to the point where we do a side by side test to see what circuit is most efficient lumens/watt.  Joule Ringer, Aircore, CrossOver, Joule Inverter.  They all operate at high frequency, converting DC into chopped pulses of power.

That's what mine did also on straight 12vdc.  just a very low light blink.  I tried this with the various configurations you show with the transformer and it does surprisingly well with a 2.8 watt LED bulb.  I think the brightest was from the crossover setup(one side of primary shorted to one side of secondary).  I got light with a current draw of 6 ma, 12 ma and 17 ma depending on how I had them hooked up (12 Nicad drill pack).  The brightest was the crossover and was only drawing 12ma.   Neat circuit but it didn't work with another 120 volt LED bulb so it can be picky. 

Brad,  I'm sure based on the above that it's very dependent on the circuitry in the 120 volt LED bulb.  I think the bulb that worked for me was a Philips from Walmart.

Wow....   Here's another one I like.  I just hooked the bulb in series with the battery and the secondary (higher winds) of the transformer.  Primary not hooked up to anything.  The bulb lights but is dim.  Then I short out the primary and it gets brighter.  But here's the Wow part .... take the short off the primary and it stays bright - actually it gets just a little bit brighter when I remove the short - and as I mention below is actually drawing less current while brighter.   Cool! 

Also checked the current on this setup.  When I short the primary the current draw on the battery is 16ma but when I take off the short it's 11 ma with NO change in brightness at all.   OOPs I was wrong after taking a closer look again it actually gets BRIGHTER !! when I remove the short and is using LESS current !!!     This part will be just the opposite depending on battery polarity.  If your bulb gets dimmer doing this reverse the battery polarity.

Just to share,

Here picture of my homemade LED used in the above video. I think it is not a dimmable one.
