And the MicroStream, apparently its not new, been out a while.

I'm carrying it in my pocket, nice and small, has lasted a week or two with daily use and still doesn't need a replacement battery.

My requirements were Non-Rechargable, Alkaline compatible, small, bright. Love both of them so far. I'm carrying both to see if I like one better than another for daily use.
