Hi Skywatcher,

I am having mixed results with the circuit. My 220v rated 5w led bulbs will light on at full brightness UNMODIFIED. It will NOT light when modified. A 220v rated 7w when connected separately (with all 5w removed) will blink continuously unmodified but shines brighter. I haven't tried to modify it, but what is causing the blinking?

Thanks in advance

Hi naija, make sure your 5 watt modified led bulb is in proper polarity orientation and if it still does not light, your coil may not be outputting enough voltage for those higher 220 volt bulbs, you would need more coil turns then.
My bulbs are lighting brightly with around 56 volts showing on the buffer capacitor, so the original driver circuitry was a step-down circuit.
Your 7 watt bulb is blinking, because the driver circuitry inside the bulb, is not getting enough power to keep the circuit running continuously.
Most led bulbs have different circuit types inside and they waste power, which is why i removed all driver circuitry from my led bulbs.
By doing so, my modified 5.5 watt-120 volt led bulbs, light bright enough to burn spots into my eyes instantly from 8 feet away.

Thank you for your quick response Skywatcher. The voltage at my own buffer capacitor with load of one 5w bulb 220v rating is 320V! Should I increase the amount of turns on the coil or decrease?

Hi naija, So if you checked that the led bulb is in proper polarity orientation, connected to the buffer capacitor, meaning flip the led bulb connections around and see if it lights up.
And if it still does not light up, then one or more of the leds on the board are blown, or you did not modify it properly and you have a faulty connection somewhere in the bulb itself.
You have to be careful when connecting the modified led bulbs to the capacitor, if the capacitor has much voltage above the rated led board forward voltage, that capacitor will dump high current and blow the leds very quickly and you will see a small black dot at the center of a blown led.

Thank you Skywatcher, I see the red blobs on the center of ALL the leds. Now, how do I solve this problem. Should I use the same capacitor value in the bulb circuitry to avoid destroying another bulb? In this case, 400v 4.7uf?
Should I reduce the number of coils to reduce the 320V across the buffer capacitor?

Hi Skywatcher, I just measured the voltage drawn by the leds when connected to normal grid electricity and it is 8.5V. The internal circuitry steps down 220V to 8.5V in order to drive the leds. Now, what size of buffer capacitor do you recommend to use in your circuit to operate these 5w bulbs without blowing them up?

Hi naija, a 400 volt, 100uF-150uF capacitor is fine, 4.7uF might be a little too small, not sure.
If that is true, that your led board is rated at 8.5 volts, then 320 volts will surely blow them every time.
So i assume you removed the internal circuitry from the led bulb that is blown, i should have told you to verify the forward voltage of the led board by applying voltage incrementally with straight DC current.
So i am telling you now, any led bulb you modify, check to see the approximate forward voltage.
So the main problem with your led bulb, if you are using 12 volt input to the oscillator, then the modified led bulb will see the full 12 volts, direct from your battery or power supply and instantly fry the leds with all that current.
If you are going to continue to use that model of modified led bulb, you would need to use probably 4 volt input to the oscillator.
This is to prevent direct current flow into the leds and only the flyback spikes can flow into capacitor and/or leds.
I have found, that these radiant spikes like to charge to a higher voltage level, because they are naturally higher voltage and low current.
So the modified led bulbs i use, match this output better.
Can you share some pictures of your setup.
peace love light

Hi Skywatcher.
I replicated your circuit and it gives interesting results.
First i used 9 led bulbs of 7 watts each at 220v with an              old 5v phone charger and it lights pretty good.Then i         modified all the bulbs and the bulbs are rated at 36v but            the light its far better.
Now i switched the input with 3 1.5v batteries but at output i
conected another 3 1.5 batteries plus 3 leds in paralel.
I used the light for 12 hours and the batteries still has the
same voltage.

Hi casiano, glad to hear you are having good results, do you have any pictures or video to share.

I picked up 4 more of the same model led bulbs today and converted 2 so far, so the setup now has 10 modified led bulbs and will have 12 total, when i modify the other 2.
There is now even more useful light illumination and the wattage reduced to 7.16 watts, from 8.2 watts.
Based on these results so far, i plan to pick up another 4 pack of these led bulbs, so i will then have a total of 16 modified led bulbs.
Actually, it appears to me, that by adding more led bulbs, we can maintain the same practical illumination as the 8 led bulbs, while reducing the input watts.
Because i notice the area where i did not add more led bulbs yet, it is slightly dimmer, but not much at all, though more illumination in the areas where i just added the 2 latest led bulbs.
So, i conclude, that when i add the other 2 led bulbs to the area where it is slightly dimmer now, that will compensate and probably lower the input watts even further.
This seems to be confirming my theory, that we can get more and more practical light output, by using more and more led diode material.
Let me explain this another way.
Say we start with one 8.5 watt modified led bulb, powered to the full 8.5 watts and this bulb outputs around 800 lumens.
The leds from that bulb may be intense, though the practical, full area illuminating capability of just one bulb is weak.
However, if we take 8 of those bulbs, using this oscillator setup and use the same 8.5 watt input, the light intensity may be somewhat lower, though the real world practical illuminating effect is far greater.
And i know some claim this is just because we are spreading around the light, though i say it is because we are using more led diode material, somewhat along the lines of Joseph Newmans teachings.

Hi Skywatcher, I don't know why but am not able to upload the picture of my setup via my android device. But I will do so when am able to work from a computer. Meanwhile, I have been able to light up my modified 5w led bulbs using a 12ah 12v battery. It is a little less bright in comparison to an unmodified 5w powered by grid power. I am not yet able to achieve the illuminance that will burn spots in the eye or the heavenly effect as you earlier described, but I will keep on tweaking.

Hi all, so something sparked my curiosity, and was pondering this idea about using more led diode material.
So i decided to hook up my boost converter and dial it in to a similar voltage that my oscillator capacitor was at.
This is not meant as a comparison between my oscillator and the boost converter, as my oscillator is not built as efficient as it could be.
This test was meant to see if the boost converter was worth using and to have a more controlled higher voltage power supply, to test the more led diode material idea.
Well, i hooked up all 10 modified led bulbs to the boost converter and the bulbs are a little brighter and slightly more white in color, this compared with my most recent testing with my setup at 7.2 watts.
This is nice, even nicer is the fact that it is using only 5.2 watts from a 12 volt tractor battery to accomplish this,
or 420 milliamps at 12.36 volts.
Of course for normal use, i will use the 12 volt computer power supply, to power the boost converter.
Seems to be a very useful setup.
Here is a link to the boost converter I'm using.

So,the circuit without the load draws 7.8watts,but when i turn on the lights the power consumption is always 7.8watts.
Could someone explain why?

Hi casiano, very nice, thanks for sharing the pictures, just like they say, they are worth a thousand words, hehe.
Yes, your coil/core looks like it would be more efficient than mine.
If you really want to make those led boards effective, spread and space them out somehow and then add some more if you can get them.
Either way, looks good.
peace love light

Edit: the input stays the same, because once the capacitor is powered up, the only thing adding to the output is the spikes and that doesn't affect what you input, because that is after the fact.
