Rode in today with the brightest battery, the 3.7v LiIon single cell. Light set on "high" - Brightness was great, but it went out at about 28 minutes. I could turn it back on but it went back out in about another minute. I put it on Medium and it lasted the 8 minutes in to work.

Since medium power is probably no brighter than high with 2x AA NiMH, I'll probably try the AA cells next.

In the end I may just use this as a backup, at least as long as my HID continues to work. The HID has hours of runtime, so I only have to bother charging it once a week or so, and that convenience counts for a lot.

[EDIT] - if nothing else, this flashlight is useful for reusing old batteries - I just dropped a mostly-dead single AA cell from the battery recycle bin in it, and it's been burning fairly brightly for 20 minutes already.
