Welcome to the forum.  Those are some nice looking lights you have there...good work.  It is great to see people using these circuits to make lights that can be used daily, and use batteries that others have thrown away.  I look forward to seeing more of your projects.

   Hi Bill.   


    In loaded conditions how low in volts can the battery get before the lights go out?  I'm just thinking of making batteries out of saltwater and junk metal for some nearly free energy. ::)

With these new surplus flash circuits...I don't know.  The other JT's would usually get down to about .3 volts before the light was not good anymore.  As my batteries get down on these new lights, I will check and keep you posted.

Let me know how you make out with the cells.  That sounds very interesting.

100 LED bench light that I run on the mains but, I made a portable JT using regular plugs and it runs from that as well.

I have no idea why some of this video got cut out during uploading.  I will make another one that shows the portable JT power box a bit better.

Here is my JT portable power box.  Very easy to make and very helpful on testing leds for possible use with flash circuits.  I re-did this as it was supposed to be in my earlier video but it got cut somehow.
