Fenix E01 Impressive Runtime

How can the CMG IUG still be running? What batteries are you using? In my runtime test I could only get 10-12 hrs as I posted before. :candle:

These are all running on NIB Duracell coppertops, I will have the dates when I dig them out after the test... (They were not recent purchase.) 53 1/2 hrs. so far BTW... Titan and Quark only on for photos, not runtime. I am as impressed with all of them as much as you!

Out of curiosity, I redo the runtime test using Duracell coppertop and Duracell Ultra...

both type seems to gives approx. the same runtime >> ~12-13 hours on Sun-mode, ~8 hours on moon-mode

During the Duracell Ultra test, the battery vented at the end of the test. When E01 turn off at hour 20+, the head is very stiff when attempted to unscrew. The moment I reach the o-ring, a loud "spark" sound was heard. I quickly tested the light with a new battery, it seems to be working fine. A quick inspection of the vented battery reveal no physical damage, voltage reading 0.934V after rest for 3 hours. :sweat:

Note: These Duracell batteries are made in China.

I agree these make great keychain lights. Bought a dozen a year ago for friends and they were all delighted. For opening a door, the runtime isn't a big deal, but I really appreciate the tests.

9:30 am, 65 hrs. With a shot of my other EO1 on a fresh Energizer lithium... I know the lithium does not run near as long as the generic coppertop, I wonder if the Duracell Ultra is the same way?:shrug: EO1 is down to about as bright as the Titan, everybody else still going. USA made Coppertops, 2016 dated... EDIT- EO1 just gave up the ghost, not quite 661/2 hrs... Everyone else still going.

Scout, I think your neighborhood must abide by different physical laws than mine to get such results .....off to do some more runtime tests of my own.....:wave:




I don't really know what that smiley is for, I have never seen it used. I thought I'd try it out here and see if it fits...as in like my tests will be turds compared to scout's...I have no idea. :thinking:

nbp- Matterhorn stopped about an hour after the EO1, Infinities still running... :shrug: I'll be happy to send my EO1 and Infinities and some of the Duracells I am using to a third party to let them run the same tests... After some legoing, I also fount my Peak Eiger will run on a regular AAA when I thought it needed a Li-ion to power it. It has been the weekend of small lights here at casa scout.:twothumbs Maybe starting tomorrow, I'll run all of my AAA powered lights through the same paces. Thoughts? I would start a new thread...

Go for it! I love these runtime threads!

Right now I have my CMG IUG and E01 running. I'll keep checking on them and see how it goes. Right now we're at almost 2 hours. I don't mean to make it seem like I think you're making it up, I just am amazed at the times you got, way more than we were told the E01 would do, and WAY more than I had gotten for the CMG. Apparently the Gerbers are DD so they go forever but the CMG is regulated, so how you could get 6x longer run than me is baffling. Let's see if I can duplicate it. Maybe I screwed something up last time.

nbp- No problem! no time like the present. New thread starting, with a few new friends. I believe the key is just letting them run, no turning on and off... Infinities are now at almost 74 hrs. and still going...

Just short of 9 hours and the CMG and E01 are still at full brightness. If things go as I expect, I will wake up to find the CMG dead and the E01 in moon mode. I don't figure I'll get results like scout's. Who knows? I'll update when I wake up. :tired:

Pic from about 2 hrs. ago, at 96hrs with the Infinities... Still brighter than the Titan, I will post a side by side with the Titan at 100hrs...

The CMGs are running way longer than I expected as well. I noticed mine run around 10ish hours before they fail to turn on, but I have never done a test where they stay on continuously until they die.

When I got up this morning the CMG was dead. So somewhere between 9 and 16 hrs it died. This is concurrent with my previous runtime tests. I seriously think that there is something different about scouts lights....

The E01 was still going, but at what appeared to be a reduced brightness. I turned it off since I would be away all day, but I will turn it back on when I get home and run it overnight. I did take a cell phone pic when I started and I will take another when I restart the light for comparison. A pic from the same orientation gives a pretty good indicator even if the camera isn't that good. I'll report back again later.

nbp- picture from 100hrs. and 26 minutes. Sometime since last photo, the green Mil. infinity started flickering ever so slightly. Titan on far right as comparison. I will give both batteries a proper sendoff, as I am sure there is not one iota of juice left in either. I am leaving the black one run, but am calling it over, as the Titan on low now gives as much light as the Infinity. Sorry!:duck::grouphug:

That is truly amazing! As I said, I can't even dance around those numbers with my CMG. :bow:

I did resume the test with the E01 though, and after comparison via photo, I actually believe that it is still running in sun mode, and that the output has not yet reduced as it appeared this morning. That would put it at about 17 hours right now. I will check it again when I get up and see how we're doing.

The newer Gerber Infinity Ultra and Gerber Infinity Ultra-M have much longer runtimes than the old CMGs.

Not done any run tests but I bought a Gerber Firecracker on an offer price as I read a member saying good kit.If I got a proportion of those long times I would be more than happy.

I'm sure that member would be greenlight, he's a big fan of it, as am I. I want to say he or some other member did a long term runtime test and got very good results, but I can't find that anywhere.

I had a Gerber Recon - M I sent back as it seemed weird with a small spot instead of the flood of the Infinity Ultra I was used to.

so I'm shelling out big $ for L92s...for nothing? :thinking:
