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.

I got my boost converter and set it to 36 volts,1 amp.  When I powered it up to 3 twelve volt bulbs in series the module electronic package inside each bulb burned out. Before the modules burned out the light output was the highest I had ever seen.  What safe dc booster voltage will the bulb leds operate with the burned out module removed and a direct connection made?   Looking at all this however I now can see a much lower watt figure to operate the bulbs using a DC boost converter.

Hi magnetman, sorry you fried the drive circuits on your bulbs.
It's probably because the drive circuit has a full wave bridge going into the circuit and this means you were not actually placing them in series.
It was probably the same as placing them in parallel, minus diode voltage drops, so then each circuit was getting 36 volts.
The forward voltage for the led board on my 12 volt led bulbs, is around 20 to 24 volts.
Best to start low and have amp meter connected to input of boost converter, until you get to the 7 watt input or a little higher, taking efficiency loss into consideration.
Then you can check the output voltage of boost converter and see the max voltage of each led board.
peace love light

I have taken the burned out module out of ""ONE"" 12 volt 7 watt LED bulb and ran wires straight from the bulb base to the bulb - + bulb light plate. In this configuration what safe booster converter voltage would you recommend as a starter with no split positive battery charging involved for one modified bulb?

Hi magnetman, the boost converter will not allow you to go below the input voltage, so start from there and raise output voltage while having an amp meter on the input of boost converter.
Then adjust output voltage so you get around 7 watts input, or whatever the wattage of your led bulb is and the voltage at the output of your boost converter, under load, is your max. led board voltage.

After burning out 5 led bulbs module packages I now found what will work with a unmodified bulb using the booster converter.   12.5 volts to a single 7 watt led 12 volt bulb at .53 amps.     6.625  watts is the OUTPUT on a parallel connected single 7 watt bulb.  BULB CONTINUOUSLY STAYED BRILLIANTLY LIT.  Nothing burned out.    INPUT to the bulb was 11.75 volts at .67 amps.  7.8725 watts.  84.15% efficient.

Hi magnetman, looks good, are you going to add more bulbs in parallel and are you going to try and compare that to the modified bulbs, since you have them anyway from the fry mishap.
That boost converter sure looks nice, with the digital push button settings, may have to get one of those.

The fry mishap took out the bulb light plates also.  Will order more 7 watt 12 volt bulbs and put 10 in parallel unmodified and see what the results are.   The 900 watt boost converter has a real nice feature.  When you set up the voltage to where you want it -- a press of a button shows the current also. All readings are OUTPUT.  I have another INPUT meter that shows voltage, current, and watt value. I dropped the voltage down to 12.31 volts to be sure I don't burn out more bulb modules.

Hi SkyWatcher 123,

Do you think the boost converter with split positive light and charge method might work with ten 7 watt 12 volt unmodified bulbs in parallel?   I have many 12 volt 1.2 amp hour batteries.  I would only power all the parallel bulbs with 12.31 volts to be on the safe side. Why I am keeping with the unmodified bulbs is because if this pans out no one will modify a light bulb later.  They would rather just be lazy and buy a stock bulb- plug it in for results.  This goes for 120 volt AC led bubs also.

Hi magnetman, yes it would work, though the current flow would be high and would require some big capacity batteries, to be closer to the C/20 healthy charge/discharge rate.
My results using the split positive method off the booster output, powering a 12 volt non-modified led bulb are still not conclusive.
Meaning, it needs more testing to see if it is of benefit or not, though for me, it was not looking so good.

Hi all, Hi magnetman, thanks for the links.
Just thought i would share some interesting observations.
I decided to bring all 12 modified led bulbs up to almost full brightness with the boost converter.
Using an amp meter at input to boost converter, the voltage output was around 58 volts and this gives blazing light in the room.
That is using 22 watts and if they were powered by the ac grid, it would be 66 watts.
If i raise the voltage a little more, the brightness increase is barely noticeable, though the input more than doubles.
So, that is 1.83 watts per bulb at what i would consider at least 90% of full brightness per bulb and raising it further makes little difference anyway.
Seems a rather efficient way to light up a home, though remember, these are modified led bulbs, which helps the efficiency apparently.

Hi SkyWatcher 123
When you modify the led bulbs do you discard the frosted plastic dome cover and just use the bulbs light plate?  Specifically what 12 bulbs were modified- Sold by and watt rating for this experiment?

Hi magnetman, this is the closest bulb i can find on the website, though mine are the non-dimmable version.
https://www.meijer.com/product/home-improvement-auto/electrical/light-bulbs/led-bulbs/meijer-led-55w-a19-es-soft-white-40weq/t1/t1-873/t2/t2-10048/t3/t3-1123/t4/t4-2200/70882034106.uts

I don't know if these dimmable ones have the same led board as mine, though if you have a meijer store in your area, you can go and see if they have the non-dimmable ones.
Otherwise, maybe some other equivalent 40 watt led bulbs can be used, though they might have a higher led board forward voltage, though i think your new boost converter can go higher in voltage and that would work.
Yes, i removed the plastic dome on all the led bulbs for more light, just don't look at them or you will be blinded temporarily.

Hi all, just want to share another observation.
I bought a couple 60 watt equivalent GE HD 10.5 watt led bulbs.
I placed those and a couple of 40 watt equivalent 6 watt ecosmart led bulbs into the can light assemblies.
That is using 33 watts input power from ac grid power, no modifications.
The light from those does not compare, maybe half the practical illumination.
Compared to the boost converter driven, 12 modified 5.5 watt led bulbs, that are only using 22 watts input, which light up the whole room, with blazing light.
