Some testing of the latest build by Lynxsteam; air core then add three ferrite rods (20cm long X 9mm diam).  We see the current and lux from the light box drop, but find that the Lumens per watt increases with the insertion of the rods.  I get about 113 Lumens/watt max with this system so far.

Thanks for sharing this information, Lynxsteam!!  You do very good work.

Here are data taken this morning using the latest 'blackberry' version, for comparison with the previous 'cranberry' version.

Blackberry
Air core:
11V   .738A  8.1W      728 Lum  90 Lm/W  38.1 kHz
12.8V   1.03A  13.2W  1130 Lum  86 Lm/W  33.3 kHz

3 Ferrite rods added:

11V   .258A  2.8W      300 Lum  107 Lm/W  23.7 kHz
12.8V   .299A  3.8W   432 Lum  114 Lm/W  17.9 kHz

Heres a neat trick!  http://www.youtube.com/watch?v=cXhZvyGtMrk

Joule Seeker,

Thank you for doing the testing.  While some of us are after new heights in lumens/watt, I am more interested in brightness using what I gather from the solar panel.  Considering I am using and converting energy that would heat a 2' x 3' rectangle of my shingles each day, I would rather get good brightness from my circuit.  I don't mean that to be a slight.  I am very excited that with this same circuit we can get some outstanding efficacy.  But I would have been disappointed if while attaining efficiency the light given off was paltry.

One last question.  How does the "Blackberry" performance compare to total lumens using grid power?  And lumens/watt using grid power?

 So do we have the mini version of your air coils circuit? I need something to start me off here. Like I said I will only have about 24 or so leds running in various loops. The main loop will be 20. 10 for low beam and an additional 10 for high beam. Plus 2 2 led strings for turning signals. And maybe another string of 2-4 for a stop light.
