    Was your charge different?
    No, mine came off at 1.450v but I think the difference is actually in the forward voltage of the LED and potentially in the minor differences between circuits.

    The forward voltage of the LED will have the most significant impact on the runtime, a lower forward voltage having more runtime and a higher forward votlage having less.

    Chevro,

    Thanks a ton for the new L1DCE graphs. Man that is one awesome light! 60+ lumens for two hours on one AA cell. I never thought a light that awesome would be available so quickly considering what were had only 1 year ago.

    My question is how come the L91 gives much longer runtime than the 2650 rechargable cell on Low and Medium, but has very similar runtime on high/max? That doesn't make sense to me.

    Hey Chevro (or anyone),
    With either the L1 or L2, what is the indication of batteries about to poop out on Low mode (or any, for that matter)
    Do we get erratic flickering?

    Also, what's the tail end of this light - how long until we're in the dark?

    Cheers!

    The light will go out when switching modes on low power. When that happens wait 30 seconds for the battery to recover somewhat and you can turn it on again; just leave it on a low setting.

    And a huge public "thank you" to Chevrofreak for his willingness to share his graphs and raw data with me, making my life a little easier. I will be adding his graphs to my L1D/L2D review on FlashlightReviews.com very soon.

    Thanks for the runtime graphs - these really put the capability of these lights in perspective.

    I was outside not long ago clearing snow from my driveway at night. I thought this a great opportunity to check out my new L1D, so strapped it to the handlebar in the snowblower. It was running on high for about an hour and I just couldn't get over the fact that it was putting out so much light for so long. I'm rather new to this flashlight stuff, but the fact that it didn't dim the whole time just amazed me.

    These graphs are great! Now how about a test with the L2Dce on low with all major AA cells for the sake of completeness. Just kidding of course, that would take all year! Thanks again!

    chevrofreak, I have a question concerning your runtime test of the L2D on low with Duracell 2650 mAh NiMH. Did you use new Duracell or your defective ones (high self discharge)? If it was the ones with high self discharge, it may have influenced the runtime. From what I've seen, when they get knocked by high self discharge, they can discharge as fast as 2-3 days!

    All of the Ni-MH runs were done using the new cells I purchased a couple weeks ago.

    thanks chevro!

    i guess i will use 14500, the way it act on the graph after protection kick-in you will get "extra" low and high. very unique!

    went to target and grab rayovac hybrid 2100mAh, im wondering if they run at least 50mins on high?

    hope my L1D will arrive tomorrow

    And.. thank you Fenix for this !! One of the best autonomy with only one AA cell !!

    chevrofreak i dont understand the difference between the lumens of flashlighreviews (overal output 88 = 122 lumens) and your mesures of 114 lumens ? it's the test receptor quality or other ?

    You can explain me ?

    and why the little difference about the lumens between nihm and lE2 lithium ?
    regards

    NO two lights of the same type have exactly the same performance characteristics. Variations in the components of the circuits, LEDs, etc. will cause them all to be a little different.

    Plus, the lumen readings I get are ESTIMATES, not difinitive scientific mesasurements, and therefore are open to error. If anyone wants to send the $20,000 for the Integrating Sphere and associated calibration equipment, I'll be happy to get accurate measurements... No takers? Rats.

    The difference in lumen output between Chevrofreak's and my measurements is less than 7%, and almost anything could account for that little of a difference, including mistakes in taking the readings... Considering the level of sophistication we have access to, I would say that we did a surprisingly good job by getting readings that close!

    Great graphs, It purely shows that the Lithium and NIMH cells perform best in these lights

    Sorry to be repetitive, but I'm curious as to the tail end of the L1D's runtime.
    Once the output can no longer exceed that of Low - how much time is there until there's no light at all?

    Thankyou very much

    (If no one has tried this, I'll get a flat-ish alkaline \ NiMH and see how it goes.... might not be good for the NiMH but it doesn't bother me to loose one for science)

    wow! good work.

    thats restored a bit of my confidence in me fenixes...

    the bottom line is: it tells me i have to get in in the lithium game.


    3 days and a bit more on low (E2) ? WOW!
    puts my NIMH (which ive never run down with a fenix) to shame!

    Fenix should get a deal to ship e2's with their lights in the blister pack, like the other standard 2AA lights we know...that would impress people.
