Any decent store like Costco will have a no frills light for a couple of $$,trade stores that sell to engineers are a good source as well.

The Eagletac D25A is a nice light, with a :


  • Nichia 219 D220 (CRI92)
    • Led lumen: 1325/82/10/1
    • ANSI FL-1 lumen: 885/55/7/0.5
it'll get 20 hours @ 55 lumens.

When running 14500 LiIon, the numbers will bump up a bit, and the run-time will drop.
I don't know if it will do 14 hours on LiIon.

that is not correct, youre reading the runtime at 7 lumens
the 55 lumen runtime is 2.5 hours


1. Approximately 40 or more lumens.
2. 14 or more hour runtime.
3. Takes 1AA lithium battery.
4. I do not want sos, strobe or colored leds

14 hours times 40 lumens = 560 lumen hours.. no such animal

if you study this review of the L10
you will see the Nichia version will run for 8 hours @ 30 lumens (by which point lumens drop by 50%) = 240 lumen hours

or look at a Maratac AA
5 hours times 40 lumens = 200 lumen hours

see the pattern? an AA light can give 40 lumens for about 200 lumen hours.. depending how dim you tolerate at the end of the runtime
(it will not be the same 40 lumens at the end.. Ansi runtime allows for the ending brightness to be 10% of the start.. thats 4!!! lumens, not 40..)

and by Lithium, if you mean Lithium primary, yes these lights like those. If you mean Lithium Ion, nope.

Zebralight SC52 has good runtime for AA

  • High: H1 300 Lm (0.9 hrs) or H2 184 Lm (1.7 hrs) / 116 Lm (3 hrs)
  • Medium: M1 54 Lm (7.5 hrs) or M2 27 Lm (12 hrs) / 13 Lm (27 hrs)
  • Low: L1 2.9 Lm (4 days) or L2 0.36 Lm (3 weeks) / 0.06 Lm (2 months) / 0.01 Lm (3 months)
