I would like to see someone build a small emergency LED light using a Lithium D
size battery.
That looked very much like the lithium D cells we used to use for the
Cheve Light that Bill Stone had made for Cheve in 2003. You can get them in
quantity on eBay or

Bill had the lamps made, not the batteries, which were 3-volt
lithium/sulfur dioxide type. (There are several different lithium battery
chemistries. Some, like the ones I mentioned, are conside
I take it that the lithium D cells that Stone made were not 1.5 volt?
I bought several batches of big LEDs from China through Ebay.
Each color has a different forward bias voltage and current requirement.
Some (ultra-violet, I think) need 3.7 volts - all of them needed more than
1.5 volts. (If yo
Well, even though a syntactical error was made - the question appears to
have gotten through.
(Thanks Mark!)
Of course I ment D-Cell *lights* and not D-Cells.
The first commercaially available lithium batteries - I seem to remember -
were 3.1 volt rather than the 1.5 volt lithiums that are now wid
