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.

Hi magnetman, yes above is correct.
Then you can limit the current at the voltage you choose.
I will say this though, removing the circuitry from any of these led bulbs, improves efficiency quite a bit.
Plus, even the best inner drive circuits, will only last so long.

Will the boost converter be able to light 9 seven watt unmodified 12 volt bulbs? -- Three groups of three bulbs {in parallel} --  Connected in series with each other so that 36 volts powers all through series connections ??  Do you adjust the output voltage before you turn the lamps on or after the bulbs at lit?
There is a voltage drop whenever a load is applied.

Hi magnetman, yes, the 600 watt boost converter i have will most definitely power those 9 bulbs, easily.
Hook up a 12 volt power source to the boost converter, then use a volt meter to check the output voltage, then adjust to 30 volts, then hook up your bulbs and raise voltage to 36 volts.

What do you think of this 900 watt boost converter?   Its output is 10 to 120 volts at 15 amps.
That means you can power 110/120 volt unmodified bulbs with it using 12 volts input as well as any set voltage from 14 volts up to 120 volts. (Output being 2 volts greater than input) ITS DIGITAL!

Hi magnetman, that looks like a useful boost converter.
Not sure it's as efficient as the one i have, though the description on mine says up to 95% efficiency, where this one states 85% efficiency.
So mine is probably around the same efficiency.
What experiments do you plan to try.

I am going to try lighting 9 seven watt 12 volt bulbs with 36 volts then try three  115 volt 10 watt bulbs in parallel.  I just bought that 900 watt booster converter.  Then I will modify the bulbs and work it that way.

In all cases I now have standard illumination figures to go with using my candle power meter.
So now I can compare a bulb illumination to a standard and adjust the setups output till I have the same candle power reading.  Then compare both results as far as what voltage, current. and watt values have been established.

Directly plugged into 12 07 DC volts ONE 12 volt 7 watt DC led bulb shows a current of .59 amps and a watt rating of 7.1 watts. Candlepower 2040

Directly plugged into 122.3 AC (house) voltage ONE 10 watt AC bulb shows a current of .0809 amps and a watt value of 9.9 watts.  Candlepower 3700

Now by using the boost converter module If can get lower watt values with the same candlepower illumination that will be something.

hello magnetman,
I am really interested in your search findings and results which will hopefully being a success !

I have now your given numbers related some questions :
the AC bulb consumes more power than the DC LED ,
but by candlepower/Watt relationship the  AC bulb gives 370 cp/W
and the DC  LED 290 cp/W.
Correct ?

cd(Candela) versus lx(lux) versus lm(lumen) definition

What do you mean with "candlepower"/"sterian candlepower" and how do you  measure your light intensity results ?

12,57 (4 x pi) Units lumen = 1 Unit (sterian)candlepower :
 your given candlepower (3700 and 2040) numbers multiplicated with 12,57
or AC bulb 3700/(12,57 x 9,9) and DC LED 2040/(12,57 x 7,1) as
                             lumen per Watt

AC bulb : incandescant bulb ? Halogen ?

Sincerely
             OCWL

p.s.:  DE 3912514 lamp application Dr.Pavel Imris
        nice numbers which are actually only surpassed by the Cree LEDs
        and Phillips Lab LED prototypes 200-300 lumen/W

All led bulbs used. Non modified.  Used hemisphere off a large led bulb and fitted it onto my lux/foot candle meter to have exact clearance from top of hemisphere to top of any lit bulb.
