DX brands that lie about their specs

  • sheepish Top 10 Forum Poster Thursday, August 2, 2018 7:01 AM Reply

    These are not complete lists.


    * Brands which lie about what LEDs they use and use counterfeit LEDs include:

    ALETO, AIBBER TONE, E-SMART, E-SMARTER, ESAMACT, FandyFire, KINFIRE, Marsing, Richfire, SPO, UltraFire, YWXLight, ZHAOYAO, ZHISHUNJIA.


    * Brands which lie about how many lumens they produce include:

    ESAMACT, FandyFire, IMALENT, KINFIRE, MaiTech, OLIGHT, SPO, Xin Wei, ZHAOYAO.


    * Brands which confuse the Cree XM-L with the XM-L2 (or mix up other LEDs) include:

    ESAMACT, KINFIRE, SPO, ZHAOYAO.


    * Brands which seem to have no clue that T6 is a luminous flux bin (not a type of LED) include:

    ESAMACT.


    * Brands which lie about their battery capacity include:

    BTY, DSTE, FandyFire, Goop, IMALENT, LusteFire, Palo, UltraFire, VAPCELL, ZHAOYAO.


    * Brands which use identical beam shots for very different torches and headlamps (or just fake beamshots) include:

    ALETO, KINFIRE, Marsing, SPO, ZHAOYAO, ZHISHUNJIA.


    * Brands which steal copyright photos of real cavers or divers using high quality headlamps but imply they are using the Chinese brand cheap crap headlamps, possibly even photoshopping those photos, include:

    ESAMACT, KINFIRE, SIPIK, SPO, ZHAOYAO.


    * Brands which use fake IP codes with hyphens or negative ratings include:

    Blackview (elsewhere than DX), E-SMART, ESAMACT, JETBeam (both IPX8 and IPX-8 in same listing; both IPX-6 and IPX-8 in the same listing; the brand itself uses fake codes or both fake and real for the same item), Klarus, NexTORCH, Nitecore, ROBESBON, Skilhunt (has used both IPX8 and IPX-8 in the same listing; the brand itself uses the fake codes), UltraFire, walkefire. Meanwhile, one KINFIRE torch claims both IPX8 and IP68.


    I strongly recommend not buying the above brands. You will very likely not get what you pay for.

    An IP code is an Ingress Protection rating for dust and water. It is the form. IP68, where the first digit is the dust rating and the second digit is the water rating. The highest rating is IP68, which will probably mean the device is hermetically sealed. A water rating of 8 needs to be accompanied by the specific resistance, such as 2 metres depth for 30 minutes.


    Either digit can be replaced by an X if it has not been rated, such as IPX8. It is not an IPX rating.


    Genuine IP codes do not have hyphens or negative numbers. IPX-8 is thus a fake Chinese code and probably means the device has not been tested at all and you cannot know how water resistant it actually is.


    Edit - typo.

    Difference between real and fake Cree XM-L emitters. vv


    NO! I don't know why DX screwed up the site so badly.
    Ask them.

    Stupid forum. I couldn't post both pics in one post nor edit/add anything without losing one of the pics. 


    Anyway, here's a link to other fake vs real LEDs. vv


    https://www.google.com/search?q=fake+cree+led&tbm=isch&tbo=u&source=univ&sa=X&ved=2ahUKEwiE48Ofkc3cAhWC94MKHfzRCGsQ7Al6BAgDEA0&biw=1304&bih=702 


    Btw, sheepish, you can add FandyFire to the list of brands with known fake LEDs. About a year and a half ago, a lot of new FandyFire Coke can style. (4X18650) lights were listed here and many were removed, but I'm pretty sure some are still here.


    Also, even pics that clearly show a genuine Cree LED should be questioned because they might be old pics and could now contain newer/fake LEDs. 


    edit - Another (possible) clue for newer lights having fake LEDs is if no pics of the LED are shown anywhere. 


    Up until about 2 years ago, most flashlights had at least one (often more) clear pic of the LED. That stopped as soon as everyone started complaining that many new lights actually had fake LEDs.

    Palindromic post count there ^ gasbag11: 12121.


    Also, even pics that clearly show a genuine Cree LED should be
    questioned because they might be old pics and could now contain
    newer/fake LEDs.


    That's a good point. DX has had good torches that went bad because a new version quietly replaced the old, good version, and replaced the good LEDs with fakes.


    Fandyfire added to LED lies list and lumen lies list.


    What was FandyFire doing here? http://club.dx.com/forums/Forums.dx/threadid.1434143

    Nitecore added to brands which use fake IP codes.


    Edit: Along with walkefire, which you probably won't be able to find on DX because of the sucky changes made to the search engine.

    What do you this about this torch (People.Bird(PB) M168 Zoom Tactical Flashlight LED CREE XM-L2 U2)? LED looks like it is original:

    Sorry, but linking to other sites is not allowed here. You should edit that post and remove the link.


    You can, however, post pics of it or specs as long as there is no mention (or watermarks) of other sites that are visible.

    The LED could be genuine.


    The driver appears to be an AMC7135 constant current driver. It's a linear regulator, which works by burning off the extra voltage as heat. They are quite reliable and can have multiple modes by "flicker-free" high frequency PWM - that's done by the 8 pin IC on the top of the board.


    But the bottom of the board looks like it could have more than the normal number of regulator chips. Do you have any better photos showing what's hidden behind the pill (the LED holder), on the other side of where the red wire is attached? A small bodied torch is not a good place to push the XM-L2 maximum spec of 3.0 A.


    When Chinese torch makers say "copper" they often actually mean brass, which is what the photo shows. Actual copper is translated into English by these same folk as "red copper". Brass is less than half as thermally conductive as aluminium, which is itself a fair bit worse than commercially available pure copper, so brass is definitely not a good thing for getting the heat out. However, it should provide better electrical contact because aluminium has an electrically insulating oxide coating which can cause problems if the aluminium oxidises further and gets thick enough to be noticed.


    The brass ring on the end of the torch barrel looks like it could give a nice electrical contact with the tail cap. Do you have any like that gasbag11?


    So yes, they are lying about their product. It's not copper and it's not going to be highly effective at heat transference. There's a very good reason most heatsinks are made of aluminium not brass: Brass sucks for heat conduction (edit - and copper is expensive).
