    Default Review: Folomov EDC C1 Flashlight (10440, Nichia E21a)

    Edit: obligatory 'for submission to the review forum.' Thanks!

    Preface


    A new 10440 light has hit the market! Itís on pre-order at Illumn.com, and the guys there sent an early release model to me for a look. Of course Iím interested Ė it ticks a bunch of my boxes. Nichia, BrassÖ. Hereís my review of the Folomov EDC C1!

    Official Specs and Features

    Hereís a link to the product page at Illumn. The light isnít up on the official Folomov site yet.
    Versions

    There is only one version of the EDC C1.
    Price

    The price is $34.90, and this is available on preorder from Illumn.com.

    Short Review

    Even though the Folomov EDC C1 doesnít hit the claimed numbers, I like it a lot. Itís a complete package light (including the cell) and it is sufficiently bright for the tasks Iíll use it for. I donít think the low mode is quite low enough, and the stepdowns on Turbo and High happen too quickly. But overall I am still very happy with the light.
    Long Review

    Whatís Included



    • Folomov EDC C1 Brass flashlight
    • Unbranded 10440 with charge circuit
    • Spare o-rings (2)
    • Manual

    Package and Manual


    The EDC C1 ships in a tin, approximately the size of an Altoids tin. Inside the light is held in place by some foam.

    The manual is quite nice, and includes all the specs and other information about the light. Itís a quite good manual.
    Build Quality and Disassembly


    There are a couple of things youíll notice right away when handling this light. First, is that it is indeed brass. Second, itís actually some sort of coated brass. So thereís a brass smell, and the brass weight, but the light is unlikely to patina very quickly (if at all).





    Then youíll notice that the EDC C1 is a e-switch tailswitch light! Unusual!
    Build quality is good.

    Only the tail of the light has a spring. The head end has only a brass button.
    The threads are very short, and square cut (a huge surprise in a light like this!). The body is highly decorated, which might be seen as good or bad.

    The single spring provides adequate protection for the cell, though.

    Only the tailcap is removable. The cell goes into the light in the normal orientation (positive toward emitter).

    Size and Comps

    Officially: Body Diameter: 13.5mm
    Length: 66.8mm
    Weight: 34.5g with battery




    This is a very small light! As a 10440 light should beÖ.

    Itís not the smallest AAA sized light Ė in my collection that award goes to the Olight i3E EOS. Of course that light is a single mode, and the Folomov is quite a bit more feature rich!

    Hereís the light in hand.




    Retention and Carry

    A pocket clip is included and ships attached to the light. One of the polarizing features of this light is that the clip attaches only on the head, which means bezel-up carry.

    Itís a friction clip, and can be removed. The clip itself is quite nice. It has a big mouth and ample shoulder, so itís easy to get on pockets, and roomy enough to sit easily. I would probably prefer bezel down carry (my favorite AAA light does use that setup) but bezel up isnít a deal breaker, nor something I canít get used to.
    Power and Runtime

    A single 10440 cell powers this light. Only li-ion will work; other types of AAA sized cells will not. NiMH, primary alkaline, etc. Those wonít work.

    I performed runtimes with the included cell. The light never reaches the claimed output of 335 lumens by my testing (corroborated by other more sophisticated testing measures, too). The initial output on turbo is around 240 lumens by my testing Ė still quite a respectable number. I test this to be drawing around 1.5A, too, so thereís not actually too much improvement to be made Ė this emitter tops out on output at around 2A.
    Surprisingly the light doesnít get all that hot during these tests.

    Interestingly the 30 second output is the same for Turbo and High Ė at a measured 100 lumens.

    I tested (but didnít graph) the light with an Efest 10440, and the output max is the same. No difference at all. So while the Folomov 10440 might be smaller because of the charge circuit, itís just as capable as the Efest 10440ís I have.
    See below the charge circuit on the top of this cell. Itís a micro-USB port Ė just insert the plug and charging will commence. While the cell is charging, a red indicator will light on the positive end of the cell. When charging is complete, there will be a green indicator there.
    Itís easy to see in the photo below how much of the cell length is actually charge circuit. Maybe 1/4 of the cell size? Probably a decent trade off though, because the average charger will not be all that fit for a 10440 cell. These cells need a slow charge rate!

    And this built in circuit provides that slow rate; the max charge rate is around 0.35A. Thatís probably around 1C (though I donít see capacity for the cell reported anywhere). My test (which records from the USB source) shows around 210mAh went into the cell. (And thatís 210mAh at 5V, so you could math it out to see the actual capacity Ė something like 250mAh). The charge circuit looks great, too.

    PWM

    Surprisingly there appears to be PWM on all modes except Turbo. I say ďsurprisinglyĒ, because I canít see a single bit of PWM at all. And Iím super sensitive to PWM. I call this a win, and if I were you I wouldnít worry about this at all.






    For reference, hereís a baseline shot, with all the room lights off and almost nothing hitting the sensor.
    User Interface and Operation

    Thereís a single switch on the EDC C1. Itís a tail e-switch. Thereís a nice flat rubber cover, and with little effort the light will tailstand on this switch. The switch isnít loud at all, but does make an audible ďclickĒ when Ö. clicked.

    An e-switch in the tail of a light is unusual!
    Hereís a UI table! Itís a fairly feature rich UI. There are even two groups! The default is the ďIllumination GroupĒ, which is described in the table below.
    State Action Result
    Off Click On (Mode Memory excluding Turbo/Moon)
    Off Hold Moonlight
    Any Double click Turbo
    On Click Mode Advance (LMHML)
    Turbo Double Click Special Modes (And then special mode advance) (Strobe>SOS>Beacon>Turbo)
    On Hold Off
    Off Click 3x Lockout
    Lockout Click 3x Unlock (to ďOffĒ)
    Any Click 7x Switch to Tactical Group
    Below is the table for the Tactical Group.

    Medium 40 1.2h 37 0.12
    Low 8 4.8h 11 0.04
    Moonlight 0.5 30h ~ ~
    * Measurement at 30s, per runtimes above.
    LED and Beam

    One of the very unusual things about this light is that itís one of the first production lights with a Nichia E21a emitter. This is a 3000K temperature, and >95 CRI. (To be honest, this light had me right there Ė itís great to try new emitters, and this oneís interesting in itís own right Ė and for ~$35 in a brass light Ė yes please.)

    The reflector is smooth, and coupled with the domeless nature of the E21a, provides a surprising amount of throw for such a tiny package. It also means that as a keychain light, thereís probably more of a spot than is needed. But for walking around the house at night and checking on kids or whatever, this light is fantastic!!


    These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.





    Tint vs BLF-348 (Killzone 219b version)


    This is the same shot as above, but exposed differently, for easier beam comparison.

    I compare everything to the Killzone 219b BLF-348, because itís inexpensive, has the best tint, and [probably] still available!

    Thanks for the review.

    The runtime graphs for turbo and high donít impress me much.

    I donít care much for the Folomov wave mode sequence and UI, either, but itís probably more tolerable on the three mode C1 than on the five mode 18650S.

    I agree with you, for sure. I don't like the LMHML, especially with mode memory (seems confusing).

    And yes, the runtime graphs aren't impressive, with the quick drop from their intended output. Still a fun light, if you accept those things!

    thanks for your review, and great photos
    I always enjoy your contributions

    I would like to brainstorm to try and figure out what the finish is
    1. brass contact surface, maybe etched or sandblasted, or
    2. sealed contact surface, clearcoat, or paint, or whatever..

    I sanded off the finish, so mine is now smooth brass except a couple spots on the head, which under a loupe, look like a sandblasted brass finish.

    So, Im intrigued by your observation that the finish smells like brass. Can you confirm if the surface is not sealed, or painted please?

    I had assumed it was a painted finish, because it looked like it had a shine to it, before I sanded it off.
    now Im unsure


    googling led me to oil rubbed brass, which is a paint with high metallic flake content

    so my questions are
    what kind of finish is it? metalic flake paint (known as oil rubbed bronze, even though it is actually a painted on finish), or
    sandblasted and or acid etched brass, with no sealer, that retains the germicidal and metal odor properties of brass contact surfaces?


    fwiw, the matte finish may actually be better at dissipating heat than shiny brass
    and if its sealed, would eliminate complaints about the smell of brass, for those that take issue with it

    I dont notice the smell of brass myself. I handle a lot of copper everyday, Im used to it.

    I used to be bothered by the smell, but I learned it kills germs, so now I think of it as the smell of dead germs.. re-orientation, as it were

    fwiw, I really liked the feel of the original finish, slightly grippy, in a nice way. My smooth finish is a bit more slickery, I have to be a little more intentional in holding on to the light. I only removed the finish because I thought it was sealed, and I actually wanted a brass contact surface, not paint. But maybe its not paint?.. help!;-)


    other Folomov C1 trivia
    there are a couple typos in the specs, should be:
    moon 2 lumens
    low 18 lumens

    the others are off too
    but I still like the light, and the modes, a lot
    especially the LED... its just an awesome off the shelf Warm White High CRI option.
