No no. You’re suggestion about buck converters was good. Unfortunately, my situation might not lend itself to joule thiefs or buck converters. Some experimentation will reveal more.

Red seems to have a forward voltage of roughly 1.9 at best from what I have seen so far. Maybe there's better ones. --- emailing from a cell @ceremona http://CereDavis.com On May 13, 2017 12:45 PM, "robb" <sf99er(a)gmail.com> wrote: > It's my understanding that the forward voltage of a diode is .7V and the > voltage goes up with the spectrum from red to uv.

downtown oakland radio shack is closing permanently tomorrow at 5 pm and last i checked had a good selection of LEDs at 90% off in their components section. On Fri, May 12, 2017 at 3:52 PM, Cere Davis <ceremona(a)gmail.com> wrote:
