Oscillator Powering 6 Modified Led bulbs

[SkyWatcher123]

Hi magnetman, the tractor batteries i'm using are 235cca, which some say are equivalent to around 13 amp hours, or 160 watt/hours.
Those 1.2 amp hour batteries will work fine, as long as you stay within the C20 charge rate for the battery, for best efficiency and battery health.
Bear in mind, my setup at the moment is using a higher voltage to charge the battery, so not sure how healthy that is for these batteries.
I did try the 12 volt 7 watt bulbs, modified and non-modified and they work also, though the non-modified 12 volt led bulbs are not as efficient in this split positive arrangement.
This 600 watt boost converter is a very useful device, so it's worth having anyway.
So if this setup runs for more than around 26 hours, with the wattage being drawn from the single 12 volt battery, then it is showing that we are recycling the energy and it is a useful setup.

Can you show with detailed photos how you modified the bulbs you bought from Meijers and also the box the bulbs came in.  I plan to replicate this circuit and will use the same thing you did.  All my replication of your original 12 volt circuit does is pulse the bulbs. A larger uf capacitor was no help.

Do you think I can hook up a 100 watt solar panel to your boost converter setup??  Would that work out as the power battery is going to be charged by the solar panel controller while the boost controller charges the charge battery. All the while the bulbs are lit.  A win- win situation for free energy.  I have that panel coming.

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.

There are 2 adjustment screws in the boost converter,   What are their function?  You don't have to adjust
the input much for 12 volts but what do you adjust the output for?  What kind of voltage and current does each modified  5.5 watt bulb take or require for full brilliance?? I am going to buy a boost converter and replicate what you did so that's why all the questions.    Can I stack 6 seven watt twelve volt  led unmodified  bulbs in series  {72 volts}  and power them without the split positive charge feature?

Hi magnetman, I see no problem with using the solar panel.
One screw is for voltage output adjustment, the other is for current limiting.
I have mine set to 66.5 volts output, that is not full brilliance, just for testing, as i'm still not sure this 12 volt tractor battery is liking such high voltage and low amperage.
You should be able to put seven of your 12 volt-7 watt un-modified led bulbs in series, powered by the boost converter, i think it will go that high in voltage.
If not, six in series for sure.
Though if your going to just use the boost converter output and no split positive stuff, you can do a series/parallel setup with your led bulbs.
Here are some pictures of the modified led bulbs.
This is the closest bulb i could find on the website, mine are non-dimmable though and they came in a four pack.

So the INPUT on the boost converter is not adjustable.  Its the OUTPUT that's adjustable.  You can have 10-60 volts input and be able to adjust the output voltage and current from 12 to 80 volts?  Is all above correct?  If so I determined a  series/parallel  way to power 9 seven watt 12 volt unmodified led bulbs using 36 volts and current.
