    In search of 1000 hours of moonlight with an AAA cell

    I have run a few tests this summer with a Zebralight H53c N and AAA alkaline and AA Eneloop cells. These are spread out in the Epic AAA Run-time test (low level only!) thread in pages 15-23. I should summarize them in a post at some point, but not quite yet. I am running one more test with...

    Help with 3D cell Maglite problem

    I have been fooling around with a 3D Maglite. I am considering getting a different LED to put in it. I tried rotating the existing module, and it doesn't seem to come out. Also, it now is very intermittent, works generally in a vertical orientation, but never in a horizontal one. I can't...

    Zebralight H53c N run time test with Eneloop BK-3MCCA

    The purpose of this test is two fold. One is to get a small sample look at a 10 year old (date code 15 07) AA Eneloop capacity. I've not found anyone dumb patient enough to run a test at sub 10mA. Or sub 0.1A for that matter. I'm a electronics geek who loves numbers. jon_slider request I...

    D cell run test: datiLED 3v Volt Vamp on a 10 year old D cell

    I recently purchased three Volt Vamps from datiLED, one of which is a 3V version for CR123s or other 3v primaries. I've noticed that it seems to run longer on my alkaline batteries that the 1.5V versions I purchased. I realized today why. The 3V board draws less current than the 1.5V board...

    Olight cell temperature sensitivity? ORB-163C05

    I have an Olight S1R with the stock cell, which is a Olight ORB-163C05 IMR RCR123A / 16340 550mAh 3.7V Protected High-Drain 2.75A Lithium Ion (Li-ion) Button Top Battery.I was out for a walk tonight with my wife and was using the light intermittently on medium mode. I had the light on for a...

    Keenstone CR123 battery?

    I came across this battery on the jungle site today, it seems to have fairly decent reviews, and the review meta website thought the reviews were real. What caught my eye was the price, 12 for $13. Cheapest i have ever found CR123 primaries. Anyone used these batteries? I found the...

    Copper 16340 multi mode ~500 lumnet NICHIA or other high CRI light?

    I recently got an Olight S1R and love almost everything about it. The cooler white beam is not bad, but what would make it "the best" is if it was copper. I am considering the copper S1, but figuring if I am getting another light so similar I would like to check ALL the boxes, which would be...

    Olight S1R battery capacity vs resting voltage, ORB-163C05 IMR RCR123A

    i am trying to find out if there is any data available on the capacity of high discharge IMR cells, specifically the Olight ORB-163C05 IMR RCR123A. In another thread I was pointed to some work that HKJ did here: http://lygte-info.dk/info/BatteryChargePercent%20UK.html This was very helpful...

    Olight S1R owners, what voltage does your Olight battery reach when charging is done?

    I finished the first charge of my battery in my S1R using the included magnetic charger, and measured 4.29V :faint: I think I have read that other folks have measured 4.25V, which is on the high side. I imediately discharged the battery until I measured 4.20V. Can IMR type batteries be...

    Recommendation for nimh AA cell

    I have an application where I will use nimh AA cells at roughly 1C rate daily during part of the year. I have some cells now, but they are all old and don't perform as well as I would like. Low self discharge is nice, but not a requirement for my usage, as I expect to recharge them frequently...

    Thrunite TN4A users - low battery indicator question

    I recently received a TN4A, and it seems the low battery indicator is a bit off. I believe I was seeing it flash red a fair amount when I first put fully charged duracell 2650 nimh batteries in it after using turbo mode. Then the problem seemed to go away, and I ran the light for an hour in...

    Thrunite TN4A as a bke light?

    Any TN4A users have thoughts regarding using it as a commuting bike light? Not off road use, just lit and dark roads around town.

    eveready 4 d cell light for you

    I came across two incandescent flashlights today, both of which I am not interested in keeping. One is a black with red trim incan flashlight. The bulb measures 0.9 ohm with my DVM, which just says it is not failed open. I could not the light to illuminate, I think the connection between the...

    Maglite mini 2AAA undervoltage lockout?

    I recently purchased the subject light, SP32016. I performed a run time test with eneloops today, and noticed around 3 hours the light started flashing. I was not paying close attention to the brightness, but it did not seem that it had dimmed much if any compared to fresh batteries. When I...

    super focused (thrower) AAA penlight

    I know many folks on here like super bright lights, I am not one of them. Just enough light in a super easy to carry package is what I like. I tend to gravitate toward AAA lights. Recently I discovered a 2 AAA incandescent penlight in my drawer at work. It looks super cheap, but still...

    Evolution of lumens per watt in a flashlight

    I came across a few old 2 cell AA maglights today. I compared one with fresh alkalines and eneloops to my single cell AAA maratac copper. Ridiculous. I can't believe we used to use these things and think they were great. Can you reference me to material of how lumens per watt in...

    "resistive" mode regulation

    I use the word regulation loosely in the thread title. I have a Manker E01 I use as a night stand light for using in a dark house. I confirmed something I suspected for some time, that is that the light output on the the lowest two modes is proportional to the battery voltage. I don't really...

    Manker E01 troubleshooting

    I was not sure where to post this, so hope this is not too out of line here. I received a Manker E01 open box item today, and it is immediately obvious why the item had been returned previously. The light works properly only in a very small rotation angle of the head, maybe 5-10 degrees. Any...
