    Because I have one early from DX and another friend is getting it soon from DX so I will be able to confirm/deny that DX still sells the first "original" good batch.

    Acctualy all the things that made first Yinding so great are now bad, very bad.

    The only positive thing: the second version got xml2 leds.

    I think only DX sells original Yindings...will that confirm in a few weeks.
    holy crap !!!!! that blows. the 'original' so to speak is the shiznat for low bux light. can't believe it is getting crapped-up (well I can believe it but daymn!)

    I recieved mine yesterday from Fasttech. It is also has the substandard mount and connectors! The mount wasn't too much of a problem as I ordered a Hope QR mount. The lens are flat across the face. Other than those common flaws with this version of the light the body looks very nice and to be of a good quality. I haven't yet had the opportunity to open it and have a look inside nor have i tested it outside yet.

    I wrote Fasttech about the cheap connectors. They told me to send photos and offered a replacement set of connectors. I will keep you guys posted.

    When I ordered mine, there were none to be found anywhere. I had to wait for new stock to arrive. I'm thinking this is the factory rushing to fill orders and using whatever they could get fast and cheap

    Don't hold your breath. I ordered one on Dec 9. All it shows is "acceptance" on the Swisspost tracking site. Now that I've asked them for a refund, they've gone silent. I just disputed it on my MC. This makes me 0 for 2 (Fasttech couldn't get one through the mail either).

    My Fasttech Yinding showed up today after about a month. I am letting it run down the battery now on low (case is warmish to the touch, ambient temp about 65*F). Looks pretty good, beam pattern is nice. Only thing I noticed is that a 4-cell pack shipped with an 8.4V charger, so I may use my 7.2 from other Chinese lights for this pack. I think it will be nice as a headlamp, coupled with my MS clones (1X and 5X 50mm housings) and my NiteRider Storm HID (still alive and kicking). With all that light in the snow I'm like a 1-man beacon.

    Hopefully I will test all of the lights on Thursday night, if anything interesting happens, like a light explodes, NSA satellite tracks me, or I run out of talent and crash, I will post it here.

    I ordered mine on December 18 from FastTech and got it on the 6th on Jan. I ended up making my own mount from a Gopro mount. It is nice and sturdy and will go in the same place as my GoPro. All you have to do is a little cutting with a dremel and it works perfectly. Nice secure fit and easily adjustable.

    Mine looks fine and works great. I plan on getting my nice R/C charger from home to charge the battery. It will do a better job than the cheapo wall charger.

    Mine also has the cheaper mount on it, but I did not care about that since I planned on making my own from the get-go. The connector is a bit different than the OP, but seems to stay together just fine. If I have issues, I will use one from my R/C's.

    Most of the lithium-ion batteries like 18650 which are used in this bike lights have nominal voltage of 3.6V-3.7V some call this also a storage voltage but when you charge them (let say you have 18650 cells and you charge them with Nitecore i4 charger) the will be charged to exactly 4.2V. All lithium-ion 18650 batteries are charged to 4.2V, and since you have 2S2P (2 serial 2 parallel) that will give you 8.4V, so when you fully charge this battery pack it has to have 8.4V @ output otherwise something is wrong with the cells inside the bat.pack.

    Thanks. I'll charge it tonight and check the voltage. I've read enough on this board to not trust the chargers or batteries much farther than I can fart them, so I have been dropping the batteries into an ammo can while charging. I let the light sit on my bench for over an hour last night on the low setting to drain the battery, it never got past warm-to-the-touch, and I used it again this morning for an hour while plowing. I have to say that the beam pattern is pretty smooth and fades nicely at the edges, I am not a fan of sharp cut-off.

    The crappy connector is shown in the photo on their website. The first image shows how the male end cannot be inserted completely into the female end.

    My Wallbuys clone finally arrived yesterday, only took 37 days

    The fittings and screws are nice and tight, and the cables do fit my MagicShine battery connectors. I gave it a charge last night and neither the battery or the charger showed any signs of overheating.

    I'll give it a trail test tonight.

    I thought about using a lipo battery from my R/C, but you would need a LVC so you do not damage the cells in the pack. I am not sure if the lighthead has anything like that built in or not...

    I'll be using a 2S1P 3400 Panasonic from Hung Lee. I strap it on my helmet and get plenty of run time using the 2S2P that I have now that is about the same capacity.

    On another note, check the screws that hold the front plate on. Mine and several others have been stripped.

    I am using li-po battery with a PCB cutoff at 3V/cell on a dual 7 led setup. Unless you don't need to draw lots of amps from battery it is not worth. What is your main reason to go for li-po? The price or some multi-light setup? Li-po should be handled with great care and have a good amount of insulation to prevent a bad branch on the trail to cause a fireworks from your li-po. Most of riders use original if it last some decent time or you can go for an upgrade like pannovo case and protected cells. See battery thread 2013 here - lot of info there about replacements and where you can get them from.

    Main reason: I race R/C cars and fly R/C helis, and have lots of Lipo batteries lying around. Not to mention a great charger (REVO powerlab 8). I solder on new connectors all the time. Trust me the batteries get a lot more abuse in the cars than they ever will on the bike...

    I didn't think about the LVC though...

    Hi all,
    Just thought I'd share an experience with this Yinding light. My riding buddy recently purchased one from Wallbuys on my recommendation, as the light is getting decent reviews on this forum, and the price can't be beat. Unfortunately, he received the inferior version of the light. It was lacking proper waterproofing in the screws, had the inferior connectors, etc. He purchased this light with the battery, charger, etc. I am running a recently purchased MJ 880U (XML-U2) on my lid, which I am very impressed with. We compared the beamshots of the two lights on Mt. Fromme this week and the MJ 880 appears to have a fair bit more flood and throw (albeit with a whiter colour). We suspected a bad battery pack might be the problem for the Yinding's potential, reduced performance. The fully charged battery pack for the Yinding was putting out 8.1V. This sounds a bit low (should be 8.4V). However, I'm unsure if this small discrepancy in voltage could be responsible for what seems like a reduced performance on the trail. That being said, the Yinding provided adequate light to get my pal down the trail at high speed and become completely hooked on night riding. It's certainly a good light for the price. My riding buddy wanted to get an MJ-880 by the end of the ride, however!

    If anyone has any insight on why this Yinding might not be cranking out enough light (perhaps this is as good as it gets?), it would be greatly appreciated. I was under the impression that it would be fairly similar to the MJ 880 in performance. I am, however, a complete newb to the sport of night riding, and know next to nothing about electronics. Please use the kid gloves...

    Thanks to everyone for your informative posts on the forum. I read them daily.

    Cheers,
    truks.

    If the lamp has voltage indicators I don't think it would be a big issue. When the lamp gets to the last indicator you know it might be a good idea to switch batteries real soon.

    If it doesn't have indicators you still have common sense namely, If you know how long you generally ride at night you use a battery with the appropriate capacity. If you don't use a cut-off circuit you use your eyes. When the lamp starts to dim it's time to stop using the battery. People use unprotected batteries all the time. As long as you are of aware of the issue and how to address it you should be fine.

    While deep discharge is not particularly good for lithium batteries I really don't think it would be an issue unless you start doing it on a regular basis...And, If that was the case that would be your heads-up to get a bigger battery or start using lower power levels more often.

    While I've used Li-ion batteries for years rarely ( if ever ) have I ever ran a Lithium battery to its lowest point while on a ride. The day that happens will be one big monster night ride.

    Could be your 880 just has a better driver. Then again the 880 has reflectors and yinding's use optics so they will have different beam patterns. Different beam patterns can "look brighter" if most of the light is more centered.

    As for the battery, don't be surprised if the next time it charges it reaches a higher peak voltage. Always a good idea with new batteries to charge, then let sit a good while ( half a day ) and then charge again to see if there was any self-balancing that needed to go on. With cheap batteries sometimes this can be an issue.

    In the end it comes down to this; Your friend bought a cheap light set. If it works you win. If he get's usable run time from the battery he wins. If he wants something brighter or better there are always going to be better/brighter things you can buy. If you friend likes your light he might try buying the 880 clone sold over on Kaidomain. I believe that got pretty good reviews. Note that the driver is providing 2.8A on the 880 clone. That should be very bright. That lamp uses a cell holder so if you buy good batteries you get a better battery. I'm surprise more people haven't bought these.

    The pictures on this thread showed that the MJ880 was better than the Duo Clone
    2013 Budget Light Shootout

    It's a well designed, high end light. The duo clone is 1/4 of the cost. For the price I don't think you can expect much more.

    8.1 volts, not really an issue.
    just an indication that the pack may not be 'all that great'
    or the charger is not that great. I expect my yinding pack to fail early and i have a pannovo 2s2p ready with my own 18650's when it does croak.

    however when a pack does get charged and drops to 8.1 right away, it could
    mean it is on it's way out soon. my yinding pack comes off charger at 8.21 volts.

    thing should run down to lower than 7.6 volts easily without affecting light

    The only thing is depending on where the light is mounted, you may not be able to see the indicator light. Also, does anyone know the voltage at which the indicator light changes.? Lipo batteries should not go below 3.0-3.1 on the low side per cell. Better at 3.2. A lvc would be easy and cheap to install. There are different types. Ones that will make a noise letting you know it is running down to the more traditional that will cut the power. I wouldn't recommend doing it by visual, it is better to be safe with a proper set up and it will also help the cells last longer.

    Yes, if the lamp is helmet mounted a voltage indicator doesn't help unless you take your helmet off from time to time.

    About the indicators in general; It is pretty much a well know fact that voltage indicators seem to vary from lamp to lamp. I've heard of indicators that turn red ( last warning ) that give you another half hour of run time and I've had one of my own that turned red only to have the lamp go completely out in a few more minutes. If you have indicators it's best to do a test run-through so you know what to expect from your lamp's indicators. I should also note that different batteries used on the same lamp will also produce different outcomes. Also remember that cold temps will change how the indicators work. Lesson learned....do a test run-through before getting caught out in the woods without battery power. Have a back up plan and you're good.

    Another option is to buy batteries that have a voltage indicator built onto the battery. Once again you might have to stop to read the indicator on the battery

    The lamps I use regularly ( on the bars ) don't have indicators although I do own lamps that DO have indicators. When I use lamps with indicators ( on the bars ) I usually place of piece of electrical tape over the indicators. I do that because ( usually ) the indicator leds are quite bright and shine in my face which I don't particularly like. When I need to view the indicators I just lift or move the tape. Since my regular lamp doesn't have an indicator I still have the option to run another lamp ( with indicator ) in parallel with my regular lamp if I ever feel I have the need. Since I rarely do rides long enough to approach the battery cut-off, I have yet to really need the indicators.

    Hummm...just had an interesting thought. Would be nice if someone made an indicator that would "plug" in-line with your MS compatible Lamp/battery. Money to be made for the company that makes the first commercially sold version. ( **Even better if you could program the cut-offs for each level.. )

    When I had lost the battery roulette I bought 30C discharge li-po, Emperor Fusion L702 and some other stuff. I soldered 5.5 mm bullet connectors to the cut-off PCB and I am more than happy with the performance of the lights and the battery. If you have li-pos laying around go and use them. But I would consider LVC, alarm or any other cheap stuff to show what is happening to the li-po cells. Most of PCBs that come with these cheap lights and indicators cut-ff or turn red at 2.3-2.5V/cell and that is quite a hazard for li-po IMHO.

    I didn't think about the LVC though...

    Thanks for the replies. Yes, after researching a little more. I found a LVA for $2.00 at hobby king, cheap insurance. My worry was the batteries I wanted to use we're only 2000mah and wasn't sure how long they would last with the light. I have bigger but liked the light weight.

    What's a LVA? Is it a low voltage alarm? Could you show us more details on how you plan to hook this up, I would like to know how this is done.

    Yes, Low Voltage Alarm. Just plugs into the balance plug. Google "lva hobbyking" should be the first thing that pops up.

    Sorry if this has already been answered (I got a bit lost in this thread and the battery thread...)
    Does anyone have a link to a site where I can easily purchase an extra battery pack for this light? (preferably one of higher quality than the battery pack that came with it)

    I bought the fasttech version and got it in the mail this week
    $51.02 YINDING 2*Cree XM-L U2 4-Mode 1800-Lumen White LED Bike Light / Headlamp - 1*battery pack (4*18650 / 4400mAh / 2S2P) / US plug at FastTech - Worldwide Free Shipping

    I thought this thread had a link to a group of batteries that Hunk Lee sells that'll work with the YinDing Gemini Duo clone. Couldn't find it though. Can someone point me in the right direction? I just got mine and used it last night on my bars. Ran it in low mode (to accompany my helmet mounted light) and after 20 minutes of riding, the switch on the light went red. The battery lasted the rest of the ride but I'm not very happy with the battery that came with it. I also want to switch to those screw on connectors that Hunk Lee sells. Thanks in advance!

    Also, this quick release mount from Action LED Lights works with the YinDing if anyone is interested.

    Here is a link to Hunk Lee's batteries.

    Panasonic NCR18650B 7.4V 3400mAh Protected Li-ion battery for Bike Light 2S1PM items in A-OK battery store on eBay!

    Be sure to ask for the screw type connector on the battery and the male end so you can update your light to match.

    How to you make special requests when ordering from Hunk Lee? I got one of his batteries and wished I had known..didn't have the good connectors (MS-type that snap tight). Also interested in a screw-type fitting for my Solar Storm.

    When you check out on eBay, you can add a message to the seller. I just asked him to include the waterproof screw type connectors. I emailed him earlier and he said it was no extra charge.

    They will both do the job, the left one will be a little bit slower and the right one will be about double faster...

    black wire is - (negative lead) -> outer part of connector

    You need a multimeter to find out the battery wires polarity. The red may be + but you need to be sure.

    What exactly did I get?

    Ok, so I just got two lights from Fasttech. One has a lens gasket and is soldered much better with standard machine screws holding it together. It also has a slight greenish hue when on (seems a touch brighter). The other has no lens gasket appears to be re-soldered (poorly), has standard philips head screws and projects a whiter light. So how badly did I get screwed over here? What would you do to fix it? Also wondering if its normal for a fully charged battery to set the button LED color to red directly after turning it on?

    You need to add the gasket and change the wires optionally. These seem to be soldered ugly and may fail overtime. ... and check the driver side also At least they seem to have the same optic.

    Hi, I'm new here and instead of splicing power cable why not opne up light and solder new lead directly? Is cable too short? Anyway that's what I'd do.

    So, can anyone tell me if this light is still a good light as original poster reviewed or has light changed (cheaper mfg.) as to make it not worth the price. I have a Gemini Duo and want to get another so I have bar and helmet lights. I've read the entire post and saw the links to other reflectors/lens so I could modify one of the lights.
    A few of the newest posts have been from people complaining of quality issues, changes in parts, does anyone know where I could get the Yinding like the one reviewed or are they long gone? Thanks

    In my experience the light you get this week from China will most likely be different than the one you get next week.

    my yinding does that on occasion. solution is unplug then plug back in and repeat until you get it to go green

    I think it detects low power instantly from the thing being connected, and triggers the low batt function too early. it should have a delay on that circuit. anyhow, mine does that once in a while and if I reconnect it, it will go green eventually and good to go.

    apparently returns are being recycled

    no one knows for sure wtf is going on

    I happened to get I think one of the 'perfect originals' but now they are all over the place. only thing consistent is the body shape, and circuit board inside says YinDing on it. otherwise it's all been changing around.

    what I say original:

    translucent white silicone gaskets
    TIR lenses
    quality internal paste and soldering job
    allen screws not stripped

    What surprises me is that some people don't seem to understand that when buying cloned lamps that nothing is set in stone. If you want something more concrete you buy a brand name lamp. Why do you think when the Yinding came out they were referred to as "Duo" clones? Didn't surprise me at all when the internal design was changed.

    basically this

    some maker in china will tool up and produce 10,000 units and sell them and wait for another order

    times goes by and returns come in, replacements go out

    the maker then figures rework the returns and slap into the next 10,000 run. and continue to cut costs and cut costs forever.

    only if a buyer demands quality and pays a premium will the maker put more effort in a production run, otherwise the lights start out as 'pretty good' and as time goes by they get diluted with junk. scraps get picked up by third parties and resold perpetually, including failed laptop battery packs which are reinvented into 3x and 4x18650 light battery packs.

    you get what you pay for and the retail price for 'big name lights' is about market value for well constructed, tested, QC'ed, proper light systems. DX, alibaba, etc is the opposite end of the spectrum. chinese lights can be a total money saver but you cannot nor should you ever expect them to last long. always be prepared to mcguyver it, to keep it alive....or just order more cheap replacements periodically (what I am doing...sometimes you land on a light that really does it all for very lo bucks)

    Just want to share the results on my Chinese Roulette Game. Placed an order on: Waterproof 2300LM 2X CREE XM L U2 LED Bicycle Light Rotatable Bike Light & 8.4V 4400mAh Rechargeable Battery Pack & Charger-in Bicycle Light from Sports & Entertainment on Aliexpress.com Got a totally different thing.

    Did not get the Yinding (as described), but another one from SecurityIng. Did not test it yet on the trails but it does look good. Neutral White indeed; 10 stepless mode and CE certification. Was afraid I would have to pay more when shipping it to Portugal, but did not because it was sent from Netherlands apparently and because it had CE all over the package. I don't have much to say right now, so please take a look at the pictures.

    I'd unscrew the mount and see if it's sealed under there. It isn't the model shown on alibaba with the front screws and the cable exiting separately with what looks like a waterproof fitting. The lightmalls clone had a barely water resistant (if at all) fitting that held the mount and cable.

    I'm not home right now, but will definitely open it up (also because I'll be using vancbiker's GoPro adapter). I'm just waiting for some other parts and the SS X2 before buying it from him...

    User review: YINDING YD-2XU2 (Gemini Duo clone)

    My yinding looks ok although the ano is scratched and it's missing orings to help keep the water out.

    Hi all I like to make my Yinding more of a spotlight as it on my lid. I looked at DX not that I like using them at Lens.

    I don't know what size of plastic bits are I have in unit. Anyone changed got a link please.

    I'm not sure what the size is, but I would check out LED DNA. TIP - Use coupon code BLF15 for 15% off your order. (I've purchased some of the XM-L optics which are currently $0.40/ea (not the $1.00 ones). Of course if these optics aren't the right size then this info is no good to you.

    This is the one you want for a spot. You have to remove the white plastic bit for them to fit. I have bought and used the 10, 45 and 60 degree lenses from there and they work great to customize your beam pattern.

    I have a little project going on for which I will be taking comparison photos of different optics with a single XM-L2 and posting over at BLF. I can PM you the link when I get it posted. I do think the 10degree ones are what you want. And I would imagine somebody has posted beamshots comparing the different optics here on MTBR somewhere.

    Anyone compare the Yinding to the Securitylng light? Thinking about getting one of these and the Securitylng is available on Amazon for $38 with free 2 day shipping. If the performance of the Amazon light is similiar to the Yinding I'll go with that one just for the quick shipping. Also easier to return it if there's a problem. I could care less about waterproofing. I don't ride in the rain.

    Ok, so I've been a long time lurker. This is my first time posting.

    I've had my eye on the original Gimini Duo and Gloworm X2 for quite some time now, but have always been reluctant picking one up due to price.

    So last week I stumbled across some of these clones on DX and ended up purchasing a Securitylng version off amazon for $39. Shipping was super fast (3days).

    My main use will be for night skiing/snowboarding. I frequently ride in between lit runs in the trees where the snow is usually still untouched.

    Everything works as expected. Although after disassembly i was a bit concerned about a few things (don't worry i wasn't expecting this to be a top notch unit, and figured it might need some tweaking )

    First and foremost, I'm not to sure how long this unit will last given the poor heat management. The LED slug only really makes contact with the light body at the two screw down locations. It maybe makes a bit of contact on one side of the slug as you can see in the pictures. Ill be adding some thermal paste around the screw mounts to hopefully give it a tiny bit more heat transferability.

    Second, obviously this isn't water proof and I probably wouldn't even call it water resistant. There's no O-ring in the back end and the giant open hole in the bottom where the mount attaches doesn't really help either. Ill try and find an O-ring for the back half. As for the hole on the bottom I was thinking about switching to "vancbiker's" aluminum GoPro mount possibly with some cooling fins milled into the side. Then seal it up with some silicone.

    Not sure if i trust the battery or not. As you can see in the pics there is some sort of circuitry included, be it for charging or protection or both i don't know. It also looks like the individual cells may have protection as well (you can see what might look like a protection circuit on top of each cell). Either way i plan on using my 5Ah RC Lipo's with inline protection (still looking for a small circuit i can add inline).

    Also, i couldn't get the power connector to fully seat. I ended up using some sandpaper to sand down the ridge a little bit. Snaps in like a charm now.

    I'm quite happy with the selection of brightness modes though. Powered up, button lights up green and starts in the low brightness setting of the 3 main settings (low/med/hi). While in any one of those three brightness setting pressing and holding the button will enter into a more detailed menu with 10 brightness levels. If the light is off and you press and hold the button it will go into a steady flash mode.

    I'll test the run time once i get some thermal paste.

    Overall I'm quite happy for the price point. Even if it only lasts me a season or two.

    On to the pics!

    (Quick shipping from amazon, packaged well)




    (Main brightness selection mode. low/med/hi)


    (Sub brightness menu with 10 level settings)


    (Giant hole in the bottom...)


    (Two small set screws that hold the back end by pressure only...)






    (Thin aluminum slug for heat dissipation)




    (Back of the aluminum slug. As you can see it really only makes contact on one side, and barely at that)


    (The two mounting surfaces for the slug, ill try and add some thermal paste here)




    (4 cell pack. 2s/2p.)


    (My RC Lipo which i plan on using)

    Whoa! I literally just minutes ago took many of the same photos of my Kaidomain Duo clone! Mine is the same except that I have a different driver without the programmable modes. How much current does yours pull from the battery pack on high? Is yours an 8.4v or 4.2v version. Mine is 4.2v (threw me for a loop as I bought it head only) and won't even run on 8.4v.

    For an idea on helping with the heatsinking, you could fill begind the emitter plate and up close to the driver with JB Weld (a permanent solution) or search BudgetLightForum.com for "Reversible Potting Option for drivers" or something like that. It uses silicon carbide mixed with "duct seal". That's my choice.

    Not sure about current draw yet. I'll be picking up a few supply's tomorrow (thermal paste and some new Anderson connectors). With the new connectors ill be able to connect to my existing lipo battery's as well as my inline Watt meter (reads voltage, amp draw, etc). I'm quite interested in finding out what the current draw is, i have a feeling that they are under powered. If they are using Cree XM-L die's they should be pulling close to 3amp's each...

    4.2v? That seams a bit odd. Each LED is rated for 3amp's @ 3.1V

    Can you post some of those pics you took?

    And thanks for the info on the reverse potting. Sounds like it might be a good option considering how poorly these LED's a set inside the housing.

    Actually, it is not that odd. It just means that his emitters are arranged in a parallel configuration. Your Securitying® lamp is likely using a board arranged in series. This is one of the reasons though that you have to read all the product descriptions when buying stuff from the Chinese web sites. If they don't list the battery or power requirements you have to send them an email to ask. While doing that you might ask them how the leds are configured as well. It can't hurt to ask, particularly if you are considering modding the lamp.

    Since you mentioned being interested in the current draw it would be more interesting to know what current is being supplied by the driver to the emitters. You could find that out if you unsoldered one of the power wires coming off the driver and placed a multimeter ( set for DCamps ) in series. Turn the lamp on high and you will have an answer. That said I don't know why it would be important unless you plan on trying to alter the driver. While I've heard of people altering the sense resistors I'm not sure that is a good thing to do.

    Anyway, I like the look of your Securitying® Duo clone lamp. I also like that it includes the variable output sub-mode for changing the mode outputs (if you choose to do that ).

    A couple questions for you: How long did it take for you to get your lamp and where was it shipped from? Since you seem to have a nice camera, is there anyway you can include some outdoor beam shots?

    I picked up the Securitying Duo clone light a couple months ago. I received mine in two days- I chose a seller that uses Amazon to fulfill the order. I think that may mean it ships from Amazons distribution center, whereever that may be. I returned it after giving it a quick test run. It throws a nice wide bright even beam with no hot spots. But when I tried to run the light on the highest brightness setting for more than 30 seconds or so the led would turn red and the light would dim. This was when riding on the road at about 15mph.

    Cheap powerful compact light. Too bad about the poor tint of the LEDs (too blue-ish for optimum detail on trails), poor heat sinking, garbage batteries and very poor waterproofing. Once I heat sinked mine, used my own battery pack, waterproofed it and changed the mount it's not bad, but I would need to change the LEDs to be happier. Still, it cost peanuts.

    Sounds like a bad driver. Did you have a problem getting it replaced?

    Or poor heatsinking? Mine (KD) ran fine for the few minutes that I used it taking beamshots and playing around with it.

    Pics will follow later when I get more time.
