Assuming the URL I sent shows the same one you have

, why the lithium battery?

- Shelf life?

Yes. I consider this very important

- More burn time than the 8-hour burn time they tout for a AA alkaline?

Maybe - though I don't know if it does last longer. After several years in the
unit, it will last longer as the alkaline will have self-discharged to a greater
extent.

Also:

Better performance at low temperature - important in cold air or water.

These aren't fancy lithium batteries - just the 1.5V AA version sold usually in
photo shops (conventional lithium are usually 3.6V or so).

This strobe has a catalytic mesh in the bottom of the unit, so any gases (H2?)
produced by the battery over time tend to be converted to relatively inert
compounds. I still don't know if it's important (since the volume in the strobe
is so low), but it's there.

Gonna order one ASAP, then.

Thanks.

Also, just realized that Princeton Tech is the maker of a little LED flashlight
("Impact" - 4AA batteries) that I got one each of for everybody in the extended
family a couple of Christmases ago. *Very* well received by all.
