Nice regulation and fantastic graphs!

Thankyou so much Chevro!
We love yOOUu!

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Wow, just awesome Chevro! I have been looking forward for these runtimes a long time, thank you so much!
And damn, the L2D is quite impressives on nimh. Wonder if any of the other cree-competitiors are even close to having that kind of excellent regulation.

Hope you like that awesome artwork Chevro, that pathetic thing took me far too many presses on the Preview button than I feel entirely psychologically comfortable with ;D

Re: Fenix L2D CE runtime graphs (L1D CE pending)

:thanks: Thanks Chevrofreak, for all the work and excellent data.:goodjob:

And no wonder it took so long, an L2D CE on low goes over 2 days continuous running? :wow: Over 3 days on lithium batteries? :wow: :wow:

The runtime curves on max have some jagged spots. I see similar shapes in both the alkaline and lithium curves. Any idea what causes that?

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Wow -- if you ever wanted to explain the difference between alkaline and NiMH batteries those graphs are ideal. Alkaline dies real fast on high, gives maybe 1/3 the runtime of NiMH on high, 60% of NiMH on medium, but almost matches the NiMH runtime on "low".

Any graph with "5200 minutes" on the x-axis deserves our most prodigious thanks !!

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Awesome work as always!!

The l2D is really versatile light. Bright as heck, but yet can be a long runtime hurricane light!!

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Fantastic! I love the regulation!
Look forward to your L1D CE runtime graphs~

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Lookin at the figures. Wow this is a great light man. A good walking light and longlong long runtime with good brightness.

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Chevro - you've just given me a new experience!

Giddy, uncontrolable laughter, looking at runtime graphs????

(I particularly liked the low one)

Good job, Sir.







Be lucky..........

Thank you very much for going through the trouble of doing these runtime graphs, Chevrofreak. They're immensely helpful to me, I really appreciate your selfless dedication to us.

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Not only do these graphs satisfy people's curiosity about the lights runtime but they let people know how long there light will last in an emergency sittuation. Many thanks for doing these graphs Chevro.

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Does any light in the world have performance that can even touch this? Over 60 lumens on high for 100 minutes on two alkaline cells, or for over 6.5 hours with two lithiums!!!!! That is unreal runtime at that output level. I couldn't imagine a better light for backpacking.


Chevro,

Thanks a ton for all your work, I know this light must have been a real ***** to finish. You rock! :rock:

You do great work chevrofreak! :thumbsup:

Plus One to that!

purely amazing chevrofreak. wow!:rock:

Re: Fenix L2D CE runtime graphs (L1D CE pending)

I gotta think that these graphs will sell some lights.. They are simply great. Thank you very much for taking the time to do these!

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Thank you, Chevro!
You burned up an 8 pack of lithium AA cells to give us those graphs so were do we send the $$ for your battery fund?
The runtimes are very impressive as low is measured in days and not meer hours. Another way to look at the UI of the L2D CE is alkaline or NiMH/Lithium. Leave the turbo mode alone with alkalines and you'll get decent runtimes. Load it up with NiMH and put it in full blast mode without worry.
After seeing the greatness of the L2D CE, I think I need to order another one since I'm moving to Tampa in a few months. Get ready for a several day power outage with a 16 pack of alkalines and a few Fenix lights.

Re: Fenix L2D CE runtime graphs (L1D CE pending)

Could I just add my thanks for the time and effort you've put into producing these run times. Its very much appreciated!
