ACEBEAM K30: Measurements and Beamshots

Dieses Thema im Forum "Flashlight Forum" wurde erstellt von toobadorz, 10. September 2017.

  1. I got my ACEBEAM K30 three days ago and performed some measurements to figure out its characteristics. Now let me share with you my results and thoughts.


    Package and Appearance

    This flashlight comes in a colored cardboard box, pretty similar to those you may have seen in recent Olight products. K30 is available in 5000K/6000K tints and Black/Sand colors. I picked a 5000K Sand one.

    [​IMG]
    Six brightness levels (Firefly, Low, Mid, High, Turbo, Turbo Max) and Strobe are available in K30. ACEBEAM is now a member of PLATO.

    K30 comes with a holster. A protective film is attached to the lens and should be removed before first use.

    What you can get in the package: the K30 flashlight, a holster, a lanyard, two spare O-rings, a warrant card, the user manual, and a card full of warnings for lithium batteries.

    The sand color is beautiful, I like it much.

    There is a lanyard hole on the other side of the head.

    The serial number and CE approval are on the tailcap.

    K30 utilizes a square thread form (nice).

    [​IMG]
    The body itself is simply a tube, offering protection to the internal battery carrier. Therefore physical lock-out is unavailable.

    A battery carrier is attached to the head with screws. Though batteries are installed in parallel, they are actually connected in series.

    I use three unprotected Sanyo NCR18650GA cells (3500mAh) to conduct the tests. They fit nicely.

    [​IMG]
    My protected EVVA cells also fit nicely.

    Thanks to the XHP70.2, now a smooth reflector can be used. There are threads on the bezel, suggesting that ACEBEAM is about to release filer lenses for K30 in the future.

    The battery indicator will start to work as soon as you turn on K30. It indicates current battery voltage in this order: Green - Red - Blinking Red. That green light is quite bright in my opinion. (Well, Gatsby believed in the Green Light...)

    Measurements

    (Note that these lumen numbers are just rough estimations.)

    [​IMG]
    • The Turbo Max output of my K30 (5000K version) is ~90% of the claimed 5200 lumens (OTF lumens @ 30s, as stated by ANSI FL-1). This is expected because the neutral white version of a flashlight usually has less output than the cool white one. I also observed this output difference on my ACEBEAM X45 (5000K version).
    • You may still activate Turbo or Turbo Max and get almost the same output as if from fully charged cells, even when the battery voltage is already down to 3.5V, though the battery indicator will start to blink in red almost immediately.
    • The battery voltage is slighly higher than 2.9V after these tests. The largest voltage difference among the three cells is smaller than 0.05V (nice).
    • No PWM detected on any of these brightness levels.
    [​IMG]
    [​IMG]
    • Cooling does help K30 offer longer Turbo Max output.
    • I would like Turbo Max and Turbo to converge toward the same brightness level. Current behavior is more like a tactical step-down, rather than a true thermal regulation.
    • K30 will become *really* hot quickly after Turbo or Turbo Max is activated. The body temperature (measured right below the side switch) will stabilize at ~55°C on Turbo Max, ~65°C on Turbo, and ~45°C on High. Do not leave the light unattended when Turbo or Turbo Max is in use. The High mode is fairly useful to me because it can deliver (almost a constant) 1200+ lumens for 4 hours, with a comfortable temperature.
    [​IMG]
    [​IMG]
    • A high-drain battery (Samsung INR18650-30Q) is not necessary for K30 to deliver its maximum output, though it may generate less heat and thus give you a bit more Turbo or Turbo Max, before stepping-down.


    Beamshots

    [​IMG]
    Shot with the other flashlights to be compared with in the beamshot section. From left to right:
    • DQG Tiny 26650 3rd (26650 x 1) (Neutral White XP-G2 x 7)
    • Manker MK34 (18650 x 3) (4000K Nichia 219C x 12 and 5000K Nichia 219B x 12, I own both)
    • ACEBEAM K30 (18650 x 3) (5000K XHP70.2 x 1)
    • HaikeLite MT02 (18650 x 3) (Neutral White XHP35 HD x 1)
    • MATEMINCO MT-18 (18650 x 4) (also known as Astrolux MF-01, this one has 5000K Nichia 219C x 18)
    [​IMG]
    All these 18650 x 3 flashlights have a similar diameter (~45mm), a size that is comfortable to hold. As a 18650 x 4 flashlight, MT-18 has a larger diameter (52mm) and is somehow not that easy to be held. That DQG flashlight utilizes a single 26650 cell and is even thinner. I personally love the diameters of 26650 x 1 and 18650 x 3 flashlights because they can fit nicely in my hand.

    (Note that this time I set White Balance to 5000K for better comparison on these neutral white flashlights. Thus you may find some differences from my previous beamshots)

    Super Bilder. Danke Dir für die Mühe, die Du Dir hier gemacht hast :thumbup::thumbdown::thumbdown:.
    Liebe Grüße,

  3. Der Akkukäfig erinnert mich an Niwalker, weil er fest ist. Schön, dass man die Akkus durch die Aussparungen leicht heraus bekommt.

  5. Nice pictures! 1200lumens for ~4hours sounds great!
    Can you tell me, where I can buy the K30 in sand-color??

    Thanks and sorry, my bad english!
     
  6. @Kasperrr

    I ordered this Sand version from a China dealer. To my knowledge this seems to be the only way to get it at this moment.
     
    Kasperrr hat sich hierfür bedankt.

    I had feared this answer... But I still hope that a german or european dealer will sale the sand-colored K30 in the future. If not than I will buy the black version of it.
     
    toobadorz hat sich hierfür bedankt.
  8. Danke für deine Ausführungen und Tests, super Bilder.

    • Ich habe da eigentlich kein Problem damit, aber es gibt einige Leute hier im Forum, die Englisch nicht so gut verstehen.
    • Kann die Diskussion evtl. bilingual erfolgen? Google hilft...
    • Danke


    Thank you for your informations and tests, nice Pictures.

    • Normaly i do not have a Problem with that, but some People in this Forum doesen´t understand English so well.
    • Could the Discussion be bilingual? Google helps...
    • Thank you.

    Thanks for your response, of course you can write in German, Google translates that well :thumbsup:. But unfortunately I can only post / answer that in English, because I know so little about German 8| (I use Google to translate the posts here for me :p).
     
  10. I can translate it by myself ;)
    I am thinking about other People.

    Ich kann es ohne Google übersetzen.
    Ich denke an die anderen Leser
     
  11. I understand english very good without google translator. But i have problems to say/write something in english...:D

    @toobadorz
    Are you from the Nederlands or from where??
     
  12. @Kasperrr
    I'm from Asia (specifically, Taiwan), so I'm able to speak Chinese and that's why I ordered flashlights from China dealers ;)

  13. OK! Thank you!
    I know Taiwan, its far away from the Nederlands :D
    If you are living there, so it makes sense to buy the flashlights and other stuff from China!
    How long takes an shipment/delivery from China to Taiwan??
     
  14. That may vary a lot, usually it takes 5~14 days for me to receive my flashlights (heavily depends on the vendor and the express service). The RMA or repairment process, which is a round-trip journey, may take even longer time (3~4 weeks). Not that fast or convenient, but acceptable :).
     
  15. Olight Shop
    Not much faster, like shipping to us..., even there is a big Distance gape....
    5 Days is even faster,...

    Nicht viel schneller als ein Versand zu uns, auch wenn es einen großen Distanz Unterschied gibt...
    5 Tage sind schneller...
