Hi magnetman, I'm not aware of the 7 watt, 12 volt led bulbs lux at 10 feet and i see the issue with your lux meter.
That is why i suggest the white foam board method, at least for me, all i'm concerned about at the moment, is usable light for humans eyes to use, so placing the white board at whatever distance, we can compare to known grid powered or battery powered led bulbs.
The 12 volt led bulbs you have, a man said in a video, they are around 600 lumens, directly powered from 12 volts dc.
Here is a new drawing of my latest circuit setup.
peace love light

This is what I  did:  I have been making videos and posting them on the U tube where millions of persons view. In each video I give directions to my Overunity.com postings.  I already have over 11,000
hits on the overunity.com site.  You might want to give this a try.  No expense involved. All you need is a I pad to make and send video clips.

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.

Hi SkyWatcher123,
When you measured the 11.79 volts at 330 milliamps was that measurement taken at the 12 volt power source or was it taken off the base of one of the bulbs in series?   This is with all bulbs lit.

What was the voltage and current with a straight shot to the bulbs from the 12 volt power source WITHOUT this  setup?

Hi magnetman, that was taken at the input, right at start of circuit.
12 volts will not drive the bulbs with the inside boost circuitry removed, but if i did make that test, it would definitely be well over 1 amp input.

Hi,SkyWatcher 123,

I noticed that when I connected my 9 seven watt,12 volt bulbs directly to my setup and powered them off a 12 volt,12 amp hour battery they were blazing white in color and my room looked like heaven with so much light.
So this got me thinking about replacing that battery with a AC to 12volt DC power source.
I found that a 100 watt 12 volt AC to 12 volt DC power source was inexpensive so I bought one.

 https://www.amazon.com/Switching-Power-Supply-Regulated-Transformer/dp/B008AG4SPO/ref=sr_1_17?s=electronics&ie=UTF8&qid=1493754094&sr=1-17&keywords=12+volt+100+watt+power+supply

Now I will have a powerful standard to compare brightness as well as determining the actual advantage of any jewel thief circuit or Bedini based circuit I build.  Awaiting the power supply now.

Hi magnetman, looks good, i have the 12 volt computer power supply that is good for 300 watts.
I tweaked the circuit some and raised the output wattage to 4.6 watts at 34 volts input.
At the moment, i have little doubt, that each of these 120 volt - 40 watt equivalent, modified led bulbs, are outputting at least 300 lumens or more each.
So what do we have then, 1200 lumens with a 4.6 watt input.
That works out to, 260 lumens per watt.
Each bulb is normally rated at 5.5 watts input - 450 lumens and 22 watts for the 4 bulbs.
Based on the wattage input to circuit, that is 21 percent of that 22 watts.
So normally, all 4 bulbs would output 1800 lumens.
And 21 percent of 1800 lumens, is only 378 lumens.
There is far more lighting in this room than only 378 lumens, is it as bright as heaven, no, but it is very bright up here.
I have made previous experiments with the 120 volt led bulbs, using oscillators like this, so i know what is possible.
This kind of efficiency is quite normal for these setups, though this particular one i've built, is doing better than most i have made.
Previously, i used a solar panel as a light meter to compare grid powered led bulbs to my oscillator powered led bubs, this is how i know what these circuits can do with led bulbs.
Really though, what matters is, is the light useful to our human eyes to light up rooms.
I'm thinking about an oscillator that will power these 12 volt, modified bulbs i have, efficiently.
What is needed i think, is something to maintain the high voltage spikes of the primary oscillator and maybe use a secondary coil to step down those spikes to a lower voltage and higher current, since that is what these prefer, since the led board is rated at around 22 volts.
Though we don't want to kill off the spikes too much, so as to maintain an impedance match of sorts, because that is where we get the extra efficiency.

Hi all, here is a short video clip showing the light output of these 4 - 120 volt, 40 watt equivalent, modified led bulbs burning brightly.
https://youtu.be/5ENoj7Wq-Zs
The input is 4.6 watts at 34 volts.

Hi all, here is a couple pics of oscillator and lights in action.
I will be using the white foam board method soon, to try and show the light level output.
peace love light

I am still figuring out what is happening.  I have a 1.2 amp hour 12 volt battery that when connected to my setup will delver a light bulb output that is good.   Now when I connect a 12 amp hour,12 volt battery to my setup the bulbs burn with an intense light  Its obvious that the greater current is responsible.

Can you explain to me exactly how a jewel thief setup can deliver a somewhat lower voltage and very little current while matching or almost matching the light output of a direct connection? Which in my case would be the 12 amp battery connected to the setup directly.  Are we thinking ""pulsating""  DC?

Hi magnetman, I would check the voltage on the lead acid batteries, sounds like the 1.2 amp one may be dropping in voltage a lot, maybe it is sulphated or the load is too much for it.
Yes, pulsing has something to do with the smaller input, also the pulses have inertia and the capacitor is using that pulse spike inertia to good effect also.
Meaning, the pulse output doesn't just end abruptly in a nanosecond, it rings and the closer we can get to resonance the better the output for less input.
With my setup, the output of the led bulbs is much better with the capacitor, the capacitor is absorbing the ringing.
In the past, i have used a 555 timer circuit making square waves, that had ability to adjust pulse width and duty cycle.
I was able with that setup, to place an incandescent tail light bulb on input and one on output of flyback of coil and get the input bulb to barely light, while the output was fully bright.

Hi Sky Watcher123,
Can you tell me in a """step by step""" fashion how to post a ""single"" photo on Overunity.com?
I have done it before but lost track as to exactly how.  I store my photos in Picaso 3 and
use a Windows 10 personal computer.

As it is I had been mailing a selected photo to myself but when I put that photo on the internet a lot of other photos in my album went with it.  I had to hurry and delete that.

How did you do it??

Hi magnetman,

Step by step:

1)  make sure the picture files you want to upload do not have higher than max 900 x 600 pixel size, you check this in any picture editor like Windows Paint and resize it if happens to be higher than that. Otherwise the horizontal width of this thread page increases too much and everybody has to scroll here horizontally to be able to read the text lines.
In your picture editor you can easily do resizing.

2) after you prepared the pictures to have the correct sizes (preferably with jpg or png extension), press the Reply button in this thread and write your text.  Then click on the Browsing icon under the Attach word SkyWatcher also referred to, you can locate this under the Text window. Then locate the file folder you picture files are and selct one file and attach.

3) to attach one more picture file you need to repeat this attachment process by clicking on the (more attachments) icon seen under the Browsing icon.

4) when you have attached the intended picture(s), and finished your reply text too, press the Post icon as usual.

Gyula

I made the below photo by following all advice and its under 900x 900.
Its my SkyWatcher  transformer replication for the 12 volt bulb setup I am going to try when my 12 volt 8.5 amp power supply arrives.  Then will have a very good idea relative to bulb brightness. Using my setup, SkyWatcher123  setup, and also comparing all to a straight shot from the power source to the bulbs without each setup in between.  Please excuse the horrible looking black tape job.  The windings under it are in perfect alignment.

Hi magnetman, here is a pic of the ferrite TV flyback c-core and multi layer 24awg. magnet wire coil with clear packing tape between layers.
The air gap shown in the ferrite core is intentional.
peace love light :)

What watt value is the 2K resistor?

Hi magnetman, that was actually two, 1 watt, 1 Kohm resistors in series on the base of transistor.
