Greetings, all - I'm new here, hope I'm putting this in the right place.
I made some trail-marker lights for a group camping trip I went on over Labor Day weekend from some white LEDs I bought from BestHongKong.com a while back, CR2032 coin cells and tape. Granted my trail marker lights didn't run at maximum brightness for the LEDs I have - but that was actually a good thing, as the marker lights lasted longer than the 4-day trip without anyone having to fuss with them.
I recently realized that finding a batch of white LEDs that work pretty well (down to 2.75v!) on lithium coin cells might be a rather rare thing. While I did retrieve the LEDs I used for re-use on another trip, eventually I'm going to need more and I'm not sure where to go looking.
I don't have a manufacturer or any other significant details on the batch of LEDs I have, other than they were listed as 10,000 mCd brightness. It's been quite a while since I bought these and they're long gone from BHK's website.
So - any pointers on finding 5mm (or 3mm, I suppose) white LEDs that will run decently off a single lithium coin cell?
