@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.

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?

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.

Cheers
