    I just got notification that mine just shipped, and I will do a comparison side by side with my original duo ( 2013) model.

    No, you were right the first time. Link from the first post. Not sure if Kir posted the wrong link. Maybe he has the XM-L (U2) version.

    edit...Oh, I see you argue on whither Fasttech or aliexpress...nevermind

    Ok...Kir specifically mentions in the first post of this thread that he has a "custom" Yinding with the XM-L2 LEDs. The link shows this as being from Aliexpress (per bohcewar). He also linked one from Fasttech first, but this I believe just has the XM-L U2 LEDs (my mistake). Trd620, just click on Cat's link to go the XM-L2 light.

    Is there a real world difference in XML2 vs XML U2?

    XML2 should be a tad brighter and a bit more efficient. I have the original Gemini Duo (XML U2) and it is bright and am currently running it as a bar light. Since I really like the size, quality and design of the Duo, I want to try the upgraded LED for my helmet.

    For my use, this should be a perfect set up. My XML2 just shipped from Aliexpress, so I should have it shortly. Once I get it I will make some side by side comparisons in regards to brightness and run times..

    Yes, but not everyone can tell the difference. If you compare the two in a head to head comparison using the same optics, driver and lamp you should be able to detect the difference in output ( on high ). Will the difference change how you ride?...probably not.

    thanks for that 127.0.0.1 will be placing an order tonight!

    Just out of curiosity would any know if it is possible to install a remote switch from a battery pack to control the light levels or does it have to go to the light head? I went for a night ride on the weekend a remote switch would have been ideal to ensure the light head does not overheat

    You won't notice brightness increase on XM-L2 leds, but you probably will notice neutral-white color of 3B bin which gives much better color rendering.

    I probably should have assumed that the poster was asking the question in regard to the available Duo-clone. That being the case yours in the better answer.
    My answer was in regard to just the LED's themselves with all other things ( amps, optics, bin and tint level ) being equal which of course at most times is not the case.

    When I first saw the beam photos of the XM-L2 T6 3B tint D-clone my first thought was that the beam shot of the XM-L ( U2 ) version looked brighter. Hard to compare visual output on warmer binned upgraded emitters to brighter/whiter bins on lower grade emitters. If I had a chance to compare both with my own eyes, only then could I know for sure. With these cheap lamps you never know when they are going to use a different driver or optic that might also change how the output looks. Like I said before, "rarely are all things equal".

    The aliexpress seller (Simon Mao) can replace the LED in the light with T5 5B1 or T6 4C at no charge - it least he did it for me (bought a total of 7 of these lights from him).

    He is not a man of many words but he ships quick and he keeps his word (ordered several lights from him off Alieypress - just sent him money via PayPal - and got my items safe and sound).

    Yes the soldering is sloppy (as seen in the first post - same was in my lights) but hey for those who don't know how to use a soldering iron it's a chance to get a Neutral White XML2 at no charge.

    I guess you can ask to replace the led with whatever he's got in stock:
    CREE XML2 LED - Shop Cheap CREE XML2 LED from China CREE XML2 LED Suppliers at Shenzhen Great Wall Technology Co., Ltd. on Aliexpress.com

    Hi All,

    Just got the XML2 version from aliexpress for $45, let's see how long it will take before it gets here.

    So you guys mentioned the battery case/holder and charger is garbage?

    Where can I get an alternate replacement?

    Can I run this of a 2 cell battery (to save weight)?
    My commute at night is only ~30 mins.

    Do they make a case/holder for 2 cells?

    Can someone school me on battery/packs?

    Somewhere down the road I might get another one of this Yinding Clone for my helmet, can I connect 2 of these lights to a single 4 Cell Battery pack?

    Thanks for all the info guys (just joined mtbr forum) and got into lighting.

    The supplied battery should be OK, you'll get a weeks commute easy on medium which is still plenty of light. Remember to waterproof it.
    You'll save only 3oz switching to a 2 cell so don't bother.

    I run a 2 cell battery with mine. I get over an hour of run time, with at least 80% of that on high.

    somewhat....your battery will drain faster on high that is for sure. medium l2 might be close to high u2 on some lights. on a 3 stage light like this is really means: ride shorter rides brighter on high, or longer runtimes on 'medium which would almost equal u2 high brightness'.
