Oscillator Powering 6 Modified Led bulbs

[SkyWatcher123]

Hi all, i will be posting updates on this 3 battery setup very often, at least everyday if i can.
The results keep getting more interesting.
I am finding, that it seems best to place all 3 batteries in parallel, to equalize them, after every test run or use.
This reveals some interesting things, that may not be apparent, if we only add up the resting voltages after a test run.
When we place them all in parallel to equalize, it shows us a more true state of charge of all 3 batteries and keeps any one battery from falling too far below any other battery.
As for the slowly improving results i am seeing, i think that the power being extracted from this setup, is probably within an ideal range for these size and type of batteries.
I have made similar tests with these batteries previously, in a 3 battery setup also, though i think i was drawing far too much power for these batteries.
Also, this dual circuit is different also than previous circuits, the capacitors could be helping transfer the charge more efficiently into the charge battery as well.
So i ran the dual circuit again for 4 hours this time, for around 120 watt/hours total so far and the batteries are all in equalization mode again.
And yet again, the voltages overall, are slowly climbing.
I will let it equalize overnight again, though i can see where it is going.
Two of the batteries will drop somewhat by morning and then a little more after they are disconnected from parallel equalization mode, however, they are climbing in voltage, that is for sure.
A = 12.565 volts
B = 12.57 volts
C = 12.565 volts
Total = 37.7 volts
We shall see what the voltage settles to tomorrow and after they have rested after being disconnected from equalization.
Your thoughts are very welcome.

Hi all, was posting about this particular oscillator light in another thread, felt it was good enough for its own thread.
It's the basic joule thief style circuit, using gutted 12 volt led bulbs rated at 7 watts from ebay.
The bulbs did contain a boost circuit inside them, to boost from 12 volts to around 21-24 volts dc, of course i removed that circuit from each bulb, for added efficiency.
The setup really is putting out a very good amount of light.
I was previously using a small number of turns on the ferrite c-core, then used many more coil layers and increased efficiency even further.
When looking at a Phillips 40 watt equivalent led bulb in a nearby can light, it is not much brighter than one of the 6000k pure white led bulbs.
Here is a drawing and some pics.

Looking at your 12 volt circuit I see you use a 450 volt, 150uf capacitor.  I have many 100uf, 450 volt capacitors.  Would one of them do just as well or would I run into problems?

Hi magnetman, one of those capacitors should be ok.
The other PNP transistor circuit is using a 330uF-200 volt capacitor and it needs more base current drive ( 2.5 Kohm compared to 5 Kohm ) to match the other circuits led bulb brightness, so it may be because the capacitor is a little more than double the capacity value.
So i would say, use the minimum capacitor uF value you can, but not too small, as it does help boost the output quite a bit it seems.
Remember, I'm using the gutted 5.5 watt-120 volt led bulb type at this time.
Each capacitor in the dual circuit, is showing around 55 volts dc.
The dual circuit is at 9.1 watts now, though that can be lowered with matching capacitors.
The setup now has all matching led bulbs, 8 of them, though i can say now, it is like the sun blazing up here.
I tested one of the warm white 12 volt bulbs the other night, without any modifications.
And on a 12 volt battery, while it was drawing 6.5 watts, it had no where near the practical illumination of these 8 modified led bulbs, it was like a spit in the wind.

Edit: I was able to dig up a 450 volt-120uF capacitor and it did reduce the base current needed on the PNP transistor and was able to raise the resistance to 3 Kohm and still match the other led bulb circuit.
Both circuits are drawing 350 milliamps and a total of 700 milliamps at 11.74 volts or 8.2 watts and outputting the same light intensity.
Maybe the PNP transistor is a little different and/or other variables, causing the need for the lower base resistance.

Hi,
I got my new 12 volt regulated 360 watt power supply up and running.  Tested 9 twelve volt 7 watt led bulbs and one 5 watt bulb in parallel. Totals 68 watts.   Voltage  11.73  current 4.99 amps.
Like looking into the sun the bulbs were that bright.  All of them   Totals 58.53 watts.  I saw your setup did a lot better so I am building it now.  I also bought a lux meter to check brightness levels.

Hi magnetman, If you are going to use the 12 volt led bulbs, i removed the inner circuitry in my tests and had decent results, though did not develop it much further.
Though these 120 volt rated modified led bulbs I'm using now, are working very well with this setup.
There is absolutely no doubt, each of these led bulbs in this setup, is outputting much more light than 1 watt worth or 81 lumens.
I would say, each bulb is outputting at least 3.5 watts worth of light or around 285 lumens per bulb.
So that is a total of around 2280 lumens.
That is close to 3, 60 watt incandescent bulbs and it does look like that much light.
