Joule Lamp

 Be careful of the eyes!  One advantage of the light box I hadn't thought of before today -- I don't have to look at the bulbs at all; the lux-meter gives me a quantitative reading of the light output without my eyes getting zapped.

  Talking about eyes getting zapped.  Last night I finally go my Exciter circuit to light up  the several CFL bulbs that I have.  So, I'm very glad to be having my eyes zapped in this case,  as it also means I'm looking at some good useable light intensity. 
  May have to wear sunglasses now...

  For my exciter circuit I placed two L3 coils that are wound on clear plastic tubes, that fit nicely one inside the other. It takes having two L3 coils, with my set up.  I also use a 1/2' toroid, as the "triger coil", a 2n2222 transistor, 1meg resistor, and In4148 diode.  The two L3 coil tubes are almost touching one another, but separated by the plastic tube. That may not be the best distance, for best results, if I separate the two tubes, I do get a slightly better output.
  So, now that that circuit is working, I'll connect it up to the solar cells, and be charging the 12volts, 4.5ah battery that is running the circuit. 
  I'll upload some pictures soon.

Joule Seeker,

Can you put in simple terms what the fantastic results you are seeing means?  For instance you are seeing more lumens per watt than the bulbs are specified to put out.  And we are inputting fewer watts than the bulbs would normally require.  What should someone expect from this type of DC converter?  Dim light and super efficiency, or good light at the same power draw as House grid?
As you report higher and higher lumens per watt it sounds really good, but we need some context or perspective.
For instance 109lumens per watt sounds good, but the bulbs are running with about half the watts they require.  Does that mean we need twice as many bulbs for useful light in a house?

Today, I made what I hope is the "definitive version" of the LynxJouleLamp.  It turned out very nice looking.  See schematic below.  It needs to be tested a lot before we publish the specifications.  I will send one to JouleSeeker for lumens testing.  Is there someone else that would like one for testing that isn't overseas?  I need someone to critique the look, feel, performance, ruggedness, safety.....Let me know here on the forum or PM me is fine too.

Here is the newest version of the LJL.  The changes were based on what Joule Seeker (Prof Jones) was finding out about lumens/watt, frequency and tuning.  Thank You Joule Seeker for your encouragement, ideas, and contributions to this area of work.  The design has come a long way from the original idea of a tesla coil based design.  Interestingly though a key aspect of making this work so well comes from Nikola Tesla's work.  And you can't beat the simplicity of Laser Saber's idea of a single reverse biased transistor.
I want to get this tested now and finalize the design.  Then I will publish the design for those wanting to build it, and for anyone around the world who finds it useful.  I will also make these for people not wanting to invest in spools of wire.  I am sure people will find better circuits and better ways to make this in the future, but this is pretty nice.

I didn't mention this in the video.  With 4 bulbs and on the high setting, frequency is 18 khz, on low setting 32 khz.

Hey All.  Nice work you guys.  I just gots to build one now.  ;] Over the weekend.

I have been reading here. might have missed some. But I got the drift.

The led bulbs. I assume that the input terminals go directly to a bridge rectifier and then a cap filter/storage in the bulb casing. Maybe a couple inductor/chokes along the way. Resistor/other circuitry?  I dont have one of these bulbs yet.

Has anyone tried to rectify the output of the coil to a cap to try looping? It "seems" that the LED light bulb is rectifying and storing. And the rectifiers in a device like these bulbs are probably not intended for the freq you guys are sending to the bulb terminals. Yet it works very efficiently. If no rectifiers to cap in the bulb, then, well, I dunno nuttin. ;]

Ill try some things. 

Thanks for all the good work.  ;]
