I'll know in a few days double x.
Z battery was down to 17 warm solitaires, 1 red 37, a few silver and a few gray. No black or blue or other colors. So I have a couple more warm and a couple of 37's coming.
I spent a while searching through my flashlight stashes and found 0 new in package 37 lumen solitaires. And none hanging around my house have a flat LED. I have incan ones in all sorts of cool colors and promo packages and plenty of 47's.
One year I gave away some at Christmas so that must have been where they all went. At one point my local WalMart had them for like $7 so I bought all they had one day, like 6 or 7 or something. Geez I thought that silver one was my oldest LED solitaire. I'll go back and edit post #81.
