Thread: What are the actual specs for Folomov Pen L1? Currently listed as same as EDC C1.

  1. #1

    Default What are the actual specs for Folomov Pen L1? Currently listed as same as EDC C1.

    Folomov currently lists the outputs and run times of the new Pen L1 using a 10900 battery to be the same as the EDC C1, which uses a 10440 battery.

    Are they really the same, or did Folomov poorly execute their cut and paste of the C1 specs to the Pen L1?

    Not much benefit to having a light twice the size, if the outputs and run times are identical to a light half the size.

    I would expect a light with a battery twice the capacity to have twice the longevity of a light with a battery with half the capacity, if they are using the same LED, driver and UI, which they appear to be.

    Just curious. I already have the C2 and the Pen L1 is on order. I don't have a C1

    Am I missing something? I'm no battery expert.

    I still have almost a month to wait for the delivery of my Pen L1, which shipped from China yesterday.

    Iíve never even heard of a 10900 battery before. Googling it tells me it doesnít have much capacity.
    If i had one day left to live i would want to be at my workplace.Because every day is like a frickin eternity.

    I didn't find any info when I googled the 10900, nothing.

    What I see is way less capacity then a AAA

    A bit of searching shows both 10440 and 10900 listed in the specs.

    Wouldn't surprise me if a "10900" is a microUSB charger + 10440 + 46mm (or so) spacer, wrapped up together.

    At all

    That would be absolutely ludicrous, but I suppose that could explain why the two lights are listed with exactly the same outputs and runtimes.

    That would be really dishonest and deceitful.

    Ya I think itís a rechargeable proprietary cell that comes with it. Like old SF rechargeable 8x or whatever they called it.

    Yes, I believe the SF "B90" battery was a (wrapped) 3x NiMH ....

    archimedes, how do I find out before I receive mine in about three or four weeks?

    I could try their contact form on their websit and see if they respond. No info anywhere else, people just post the Folomov chart that Iím questioning.

    Best bet unfortunately will be to see how it is when you get it. Only real way to find out.

    Anyone know the actual specs of the Pen L1?

    Mine never made it to me and is supposed to be reshipped.

    sad for you not to get your light still

    I think you know the answer to your question, you posted this 6 weeks ago:

    Folomov apparently just copied the specs of the C1 and didnít actually test the Pen L1.
    the best way to know, is to put the light on a meter
    if you send it to me, I will test it for you ;-)
    since I have a meter, calibrated to an HDS

    Jon,

    I contacted banggood a couple days ago and they said the the package was returned to them for some reason.

    The offered to reship it and I accepted.

    Hopefully Iíll have the lights in about three weeks.

    Thanks for the offer to do the runtime tests on my lights. Thatís very generous.

    Do you still use your C1?

    I hope that I end up liking these lights. They have a tough challenge replacing the Sofirn SF02 thatís been in my shirt pocket for the last couple months.

    I emailed Battery Junction a few minutes ago to see if they know the actual specs, since they now carry Folomov and the list the same runtime and output specs for the C1 and Pen L1.

    the advantage of the Folomov is probably the LED having higher CRI, if you can enjoy the warm color temp
    I suspect the UI of the sofirn is less confused, but the LED is a cool white low CRI.. possible modding candidate to Nichia :-)
    or, the Lumintop IYP could be an off the shelf high CRI candidate that is not as warm as the Folomov

    I dont know all the mode and UI differences between those penlights


    I gifted my C1 after finding it dead on my nightstand from parasitic drain during non use, a couple of times, plus having it come on in my pocket when I carried it for a while.. its a cute little light, just not a match for my current interests

    I also had a chance to use a C2. I really liked the beam and small size, and the included USB rechargeable mini battery.. again I like the LED, and the UI is slightly better, imo, than the C1

    have not been using my AAA lights much
    Im in a 16340 phase, using several RRT-01 High CRI Nichia modded lights, 3000k 3500k and 4500k, single, and triple,

    the rotary interface makes specs and mode sequences essentially irrelevant.. runtime is also a non issue for me.. the battery has plenty of capacity and the range of output is plenty broad for my present interests..

    I look forward to your impressions of your Pen L1
    Folomov has a unique position atm, one of the only makers offering warm E21a High CRI

    I donít like the UI on my IYP 365. It it was one of the originals with the 219B. I did just buy a half price IYP365 with 219C for my granddaughter, who just started nursing school.

    What I like most about the Sofirn SF02 are the really low ML, proper Med, plenty high high and big fat hot spot. Excellent for short to medium range tasks. The switch is also nice and firm and always does what I ask without any surprises. Itís not high CRI, but I have no issues distinguishing colors in wire harnesses and such. I actually like mode memory on this light.

    The only 1AAA that I currently carry is the Manker E02. The Folomov EDC C2 and Utorch S1 Mini have taken over hat brim use.

    The BLF A6 with 3D does the heavy lifting and the recently acquired Lumintop EDC05 and Rofis R2 get used daily.

    I will likely carry both the Pen L1 and SF02 in my shirt pocket for a while to decide which gets to stay. Maybe both will stay.

    I also really like a 0.5 lumen moonlight, as also found on the Folomov C2 (spec was accurate)

    I was less happy with the 2 lumen minimum on the Folomov C1 (spec 0.5 was Not accurate)

    also agree the Folomov C2 and Utorch S1 Mini are great hatlamp options
    I appreciate your real world impressions too

    and congrats on the growing family :-)
    Im also a grandpa, gives me great joy!

    Just by observation, the SF02 ML appears to be about 1/4 as bright as the C2 ML.

    you may be right, we will never know unless you get a meter

    fwiw, C1, C2, L1 all claim 0.5 moon, yet they are all unequal in real world, I confirmed on a meter the C1 is 2 lumen and the C2 is per spec 0.5..

    I received my two today Ė they were reshipped after I contacted the seller 8/29/19 Ė they had been returned to China for some reason.

    Very 1st impressions right out of the tin: Ė Very, very dim moonlight. Ė Very tight pocket clip Ė the tightest Iíve had on a pen light. Ė Mode sequence is LMHML. I was really hoping that it would be LMHLMH as my C2 is. I still donít like the LMHML mode sequence. Ė I like the beam profile.

    The runtime and output specs are the same in the manual as online, so I still donít know what the actual specs are and donít have a way to find out, since I donít have a C1 to compare them to or a light meter.

    as long as the light works for your application, the lumen specs may not be that important

    and if runtime specs is something you want to know,
    I think you might actually be able to just time the runtimes yourself:-)

    in any case I hope you enjoy your light

    Jon_slider,

    Runtime specs are important to me, so I may try them myself sometime, but without a meter, Iíd have to sit and watch the light continuously to observe dimming.

    The output levels donít seem to be higher than advertised, so Iím hoping that the runtimes are nearly twice as long as the C1.

    I think I might actually prefer a higher CCT emitter in this light. Maybe 4000 to 5000.

    good point that it is easier to observe the dimming with a light meter

    since you dont have a light meter, I suggest you check battery voltage instead

    when the battery is down to 3.0v, I would end the runtime test

    I dont monitor the light constantly, I just set a timer on my phone to check every X minutes, where X is 1/4 of the expected runtime...

    eg, if I expect a 40 minute runtime, I check every 10 minutes
    if I expect 4 hour runtime, I check every 60 minutes

    I prefer 4500k CCT for EDC
    I do not use 3000k for daytime EDC, it is a specialty light, that does not actually get used very often.

    for me the Warm 3000k folomovs are for simulating incandescent, when relaxing at the end of the evening, car camping, and other times when there is little or no competing ambient light, including nightstand use.

    enjoy your choices, congrats on your warm nichias :-)

    here is a color comparison between my 3000k E21a and 4500k N219b sw45


    and here comparisons to an sw45k, and a couple other CCTs and tints



    I dont use my lights continuously for long periods, so I care more about light color and CRI, than runtime, but I respect that we all have many different ways we use a light, and runtime is certainly a consideration to be informed about.

    I dont trust specs at all, if I need a runtime reference, and cant find one online, I have to do it myself.

    since there is already a review of the C1
    I would just double the runtime expectations with the Pen L1, since the battery is twice as big

    maybe someone will post a review to answer you runtime questions
    so far you seem to be one of the early adopters and I cant find any Pen L1 reviews to answer your runtime question

    I hope you figure it out, and enjoy your lighting choices :-)
