Oscillator Powering 6 Modified Led bulbs

Hi magnetman, nice looking setup you have there, thanks for sharing.
Using 3 non-modified led bulbs in series could be quite efficient, considering the radiant spikes like loads closer matched to their qualities.
As long as the driver circuitry within those bulbs, is getting a high enough voltage and current, the pulsing should stop.
Look forward to your results.

If any one is interested in my modified replication specs let me know and I will post what changes were made.  By far the coil winding is most simple to do as far as changes to the first 12 volt  original post by Sky Watcher 123.

Hi all, so i was wondering if i could equal or exceed the efficiency of the 600 watt boost converter that was bought from the net.
I have equaled or improved the efficiency by a little so far.
I used the joule thief circuit, with the NPN 2SC5359 transistor, 1 Kohm base resistor and same buffer capacitor.
Also used the same ferrite tube core, though this time i used a bifilar 18awg. magnet wire on the open core.
The circuit uses 1.5 amps at 11.56 volts or 17.34 watts.
I wonder if another layer of 18awg. wire could improve efficiency or even a thicker gauge wire, with even more layers.
I will try another layer of 18awg. magnet wire and see, will try in series and parallel and compare.

Hi all, started testing a different configuration and the results so far, are promising.
Measured the volts and amps going in and volts and amps going out into the charge battery and that comes to 81.3% efficiency.
The thing is, we are getting the good light and the charging, so 81% may be lower than it actually is.
Thoughts welcome.

What was the amp hour rating of the batteries you used?   I have a lot of 1.2 amp hour 12 volt batteries. Might they work? I see you can buy this same 600 watt boost converter on Ebay for an inexpensive price.
