    The stock lenses are pretty tight so I'd say 10-15.

    As for replacing the LED's, do a youtube search for 'how to reflow led'. You have to either buy the new LED's as bare emitters (couldn't find bare emitters in the bin I wanted) or buy them already mounted on star's. You then have to heat the star to remove them and then reflow them on to the existing. Looks pretty straight forward but since I've never done it before, I'm a little nervous. Don't want to screw up my light.

    The best place for getting answers to this kind of stuff is over on the DIY forum, just an FYI.

    Messing with these cheap lamps can be a hassle. While some are better to work with than others there are still things to consider. Even if you can access the plate or board which holds the emitters, removing and replacing the emitters might not be as easy as it looks. With the right tools it can be done but it will require some patience and a bit of knowledge. Even if you get to the point where you have replaced the emitters you then have to make sure the emitters are lined up right with the optics ( or reflectors ) so that they are properly centered.

    All things considered if you want to retro-fit your lamp with different emitters it is best that you be willing to use that lamp as your "Beta" unit. That said I would buy a second and have it standing by just in case something goes wrong.

    Personally I've never attempted to swap out emitters on a bike lamp. I've taken a look at some of the ones I have and just decided that it's just easier to just buy a new lamp with newer emitters. In the long run the cost is about the same ( if just buying a new lamp head ).

    With all this said I have a torch that I ordered a new emitter for. I already know how to take it apart so replacing the emitter should be pretty simple. I have the emitter I just haven't gotten around to finding the time to mess with it. Then again I have so many lamps and torches that it really isn't on my "must do" list. Hmmm...got some time today maybe go down to Radio Shack and buy some thermal paste and some desoldering braid ( otherwise known as solder wick )

    I am stuck with this one...Seems like it went into an overheat mode.....

    It still has the 3 modes and strobe, just at greatly reduced outputs..I guess I should pull it apart. Not sure what to look for though.

    That's weird. So you were playing around with the modes and it remained at reduced output? Have you recharged the battery pack or have another battery pack to check?

    Initially in the garage it put out a ton of light..I was like cool. Tried a couple different modes...then all of a sudden, reduced output. I took the 4 individual keeppower cells and charged them. I use one of those 4 cell 2s2p holders. Now I have the modes like I should, but the output is miniscule....on high its like I dunno, 100 lumens? very low.
    on low its like 1 lumen...it strobes , but again, very dim. I took it apart but dont know what i'm looking for. Solder looks good

    The one I got from Fasttech the thermal control halves the output... so still plenty bright.

    That doesn't sound right at all. How long were you testing out the different modes when this happened?

    But it returned back to normal after it cooled off right?

    Yes. Theres no hysteresis in the circuit so as it heats up it starts to blink high/low as it passes the set temperature before settling on low. Not sure what happens if it gets significantly hotter.... I'm sure even on medium these thing would cook if left on too long when stopped.

    I tested it for 30 seconds...went in the house to find a dark room, played with the modes and it went into this comatose state...Figure I would charge the batteries while I was there...no change.

    Step one; test it with another battery set-up, if no change then at least it has nothing to do with the battery holder.

    It could possibly be a bad power connection inside the lamp or a problem with the driver...in which case if it's the driver it's pretty much done. Try moving the wire around while the lamp is on. If there's a partially break in the wire you might see the lamp get bright for a sec. If this happens you can fix it if you can find the weak spot.

    If you don't see a change by moving/bending the wires ( this will sound stupid but..) try banging the lamp on something hard and see if you see any momentary brightness. This would indicate a lose connection inside the lamp that just might be fixable.

    Ok...been searching but can't find it...any of the folks that frequent this thread remember where the beam shots of the Yinding are with the various lens from LEDDNA are? I just ordered another Yinding (this is addictive!) so I can run one on the helmet/one on the bar and was thinking of swapping out the bar lens to get more flood. The neutral color of these things is great and I think the Solar Storm is too white to run along side the Yinding.

    Edit. Ordered 2x45-deg lenses from LEDDNA...$2...big spender

    I ordered mine from wallbuys, it's going into the 6th week now and no sign of it.
    What's the average you've had to wait for it? I used wallbuys because it sounded like they were quick compared to the other vendors

    It took them about 3 days to even confirm my order then two days to ship and about 2 weeks in transit so roughly 3 weeks for me from wallbuys

    Did you get the clear or frosted 45 deg lenses? I got some frosted and it knocked the light down too much also got 30 clear and they work pretty good, think I should just get some 45 clear versions to compare.

    Just dropped in the 45 degree clear optics from LEDDNA. Came in less than 2 weeks. Easy install, will try in a few days. Beam shot in dark garage certainly looks more broad. $2 delivered.

    So I got my second one today from Wallbuys, took a little over 2 weeks..not bad! Some issues here...this is not the same light as the one I originally bought/reviewed here. The differences:

    While the exterior case is the same, the lenses are smooth across the front instead of dimpled.
    The mount is crappy; it doesn't sit flush and sticks way out of the back (like the photos of the Yinding clone [clone of clone]). I will dremel the part down that is causing the interference. The rubber piece on the mount isn't as nice.
    The battery is shrink-wrapped in blue rather than black.
    The battery cable connectors are not the snap-together MS type, but the cheaper type that are easy to pull apart and won't be waterproof.
    The rubber bands are more like the MS type; my original came with tabbed-bands that were softer.
    The light doesn't "softly" increase in brightness when you change levels from low to high.
    And finally, the button on the back looks different and has a harder click.

    I think I got one of the cheaper more current versions..still plenty bright!

    Got exactly the same from Wallbuys yesterday for my friend. All that things + front panel doesnt have any o-rings around the body and lenses (you can upgrade that with 1mm o-rings of correct diameter that you can buy at your local store)
    The battery is crap, did not test it yet, but I fell it doesnt run more than 1h on full.

    PS: I ordered this sku
    $48.48 Yinding 2 x CREE XM-L2 T6-3B 1600LM 4-Mode Dual Head White LED Bicycle Lamp + 8.4v Battery Pack + Charger-Black
    but instead I got this one
    $46.46 Yinding 2 x CREE XM-L U2 1800LM 4-Mode White LED Bike Light / Headlamp-Black(4x18650)
    (The review below this sku is mine. It is for the sku mentioned above (original yinding) and not this crapy fake cheepo)
    Those Wallbuys are chinese fu... and I am never going to buy anything from them. Not to mention their web site is crap.

    I am still thinking on fileing complain.

    I don't think my "good" one had o-rings around the individual lenses, only the body.

    Edit: Wrong, my "good" one which appears to be the first-gen modded with XM-L2 emitters has small clear o-rings around each lens AND the whole front bezel where it meets the main body. The second one I received is certainly not of the same quality.

    Interesting, I just looked on the Wallbuys site; the one I ordered shows as the original in the pics and is sku#13047. The one I received (crappier one) is shown as well, but as sku#10809. I sold this one to a buddy so I am going to leave it alone..but if it was for me, I would go back to Wallbuys and ask for either my money back/return or have them send me the other (if it is even available).

    Its just what Wallbuys has listed for the 2 different lights on their site. One is what I got, the other is like my original. I ordered another original, and got the crappier one. I think I will take it up with them as that is crappy..but hey...its $45 and still works fine.

    Has anyone replaced/upgraded their LEDs in their Yinding? I started a thread about this in the DIY forum, but didn't get any responses.

    For the "clone" that you have recently got. Not for "original"

    Mine has 1,5h runtime on high till it starts slowly to cool down. Green light illuminates for 5 min, then goes to red fo the whole runtime.

    Ok, I didn't do a run-time test on the clone - sold it to a buddy the day I got it. I have actually talked to Wallbuys about this and am waiting to see what they will do (if anything). I want another original!

    I got some L2 T6 3B LED's to replace the ones in my clone (same issue as the other guys expecting the original) but haven't gotten around to swapping them out. I also posted in DIY for info on reflowing but no responses. Looks pretty straight forward though.

    Good job!

    Can't believe how bright this light is on low
    Looking at threads here I gone with the go pro mount mod, look so much neater and fit my lid better.

    I got an extension cable from light to battery and I stuck battery in camelbak. Local rides I look at velcro battery to seat post.

    Price I would have to look, I did get from DX but I wouldn't use them again as it took three months to get to UK! Items use to take 3 - 4 weeks.

    First ride with the Gemini Duo

    I just recently got the chance to take my Gemini Duo for a pure technical twisty single track ride at night. My experienced surprised me a bit because I found the best setting for the Duo was low, maybe medium when it got very technical and fast. I found that high was too much and gave too much glare and bounce back.

    Keep in mind, that my Gemini Duo was bought last December when the original models weren't available. Mine has the flat front and cheap connectors. With that said, I have been nothing but impressed with the light and even the battery run times. I definitely plan to buy another for my helmet. Both on low would be all the light I could ever need on my local trail and both on high would be enough for high speed runs.

    Thanks for the plug!!!!

    Lightmalls sells a clone without the battery pack, it seems that the front screws are missing, which is a no-go for me.

    Anyone brave enough to confirm this?

    I was considering getting that one, esp. because of the 2 group programmable driver (should be same as Cat's KD Tri-Clone). I didn't take notice of the missing front screws.

    We bought a bunch of these, 9 units in total.

    No, they don't have the screws on the front. There are two small allen head set screws at the back of the lamp on the underside behind the mount. Presumably they're holding the back cap/plate on. I haven't tried opening either of my two lamps to check though.

    The lights otherwise work great and the programmable aspect was one of the primary reasons I chose this particular unit. No complaints.

    Thanks! Any chance that you might open yours... for the sake of the world? (I would like to know if the front is removeable please!)

    If those pics are real photos of the lamp (not computer rendering) then the front panel is not removable (no line between the body and front panel)...so the heat managment might be an issue.

    I just got one that arrived an hour ago. I see the 2 screws on the body, and I'll probably tear it apart at some point. I got one for a friend who did Tour Divide with it after I made her battery packs to use AAs she could get on the road.

    I liked the 3 modes and the soft-steps between modes. The 10-step mode is interesting, but it takes 8 seconds to get to it and there seems to be no mode memory so you have to start over every time you turn it on.

    I really wish they had the ability to go up one level with a click and down with a longer press, as do all the lights I build.

    I removed the bar mount and undid the little allen screws, but still couldn't get the back cap off. Not sure if it's a very tight fit or glued shut, but it'll be hard to open without gouging something.

    A heads-up- when you remove the bar mount you can see that this unit is *not* waterproof at all. The cable exits a hole in the mount with no cable gland or seal. I will be replacing it with a metal GoPro adapter, and placing silicone gasket-maker sealant in the gap.

    Thanks, that's too bad. A high quality head and a selfbuilt battery stays a dream.

    Meh, that's what you get for under $40.

    I was hoping to play with the optics etc. and would use one of my home-waterproofed battery packs using 3400maH cells.

    The connectors aren't waterproof either, but I'll cut it off and replace it or make a better seal with a heat-shrink cuff. Between that and silicone around the wire it should be decent.

    Here's the light once I removed the mount and replaced it with one of Vancbiker's nice GoPro mounts. I added some fins for better heat transfer, and used thermal grease underneath. Also sealed the cable exit with silicone.

    Hey,

    I have the same headlamp and ran into the same issue the first time I tried to open it. It's not glued, just a tight fit between two aluminum pieces. You need to use a thin prying tool or the blade of a cutter to slide it open.

    I'm actually very happy with it. I replaced the lens with 15/45 degree ones for better flood, added thermal grease and I'll probably get a Gopro mount adapter for it.

    I've also got a Pannovo battery holder with four 3400mAh Panasonic cells, and after running it on medium brightness for about 5 hours the battery voltage is at 3.7V, so plenty of juice left.

    OK, will pry it open just for fun, and make sure there's enough thermal grease.
    BTW Vancbiker can make the mount with the fins now for better heat removal.

    3.7V on each cell? Or on the whole pack, what would be bad, not?

    How is the led board mounted? Does everything come out the back?

    The led board is attached by two screws on two triangular shaped lips on the inside of the case. Yes, they all come out from the back.

    U2 is brighter than a T6 but the U2 can be from the same generation as the T5, T6 etc. In the simplest terms, each batch of LEDs varies a little in their output. Manufacturers test and sort them by the output. The designations T6 and U2 just refer to the output range. Since higher output is deemed a good thing, the manufacturers price the higher output LEDs a bit higher.

    Updated versions from Cree have lately been designated with the addition of 2 in the family name. XM-L became XM-L2 for example.

    Got the light pried open. No thermal grease at all in there, and the LEDs on the board only contact the housing on the 2 triangular points, so heat transfer isn't great. I put grease between the LED board and the mounting, and carefully applied more all around.
    There are o-rings between the optics and the front of the housing.
    I also slipped a thin o-ring around the back section before reassembling to seal the housing. Thermal grease would have worked there too. With the silicone sealing the wire exit the thing is finally somewhat waterproof.

    (I build my lights a lot more waterproof than this, but it's not bad now)

    If I could change 1 of the 2 LEDs for a warm tint, it would be quite a good light.

    ^^That's one of my main gripes. I've come to terms that I got one of 'bait and switch' lights from walbuys, and even with the lesser quality, I would consider it still a good value if only the light had a warmer tint (similar to my L&M Taz), I would still be quite happy with it. Oh well.

    Sorry for not reading thru the thread but can someone tell me if the Yinding comes in the newer version XML2 LED yet. I think I read somewhere that it does but didn't find it online.

    Sorry, me being lazy.

    Also, how do you guys helmet mount it.

    Maybe I better read thru this thread.

    The lightmalls one is XML-2.

    They also sell a helmet mount that work with it:

    I used a metal GoPro adapter from Vancbiker and can use a GoPro helmet or headband mount, but he makes a less expensive plastic one too.

    This is probably one of the best batteries you will find, with real Panasonic cells and actual capacity as advertised.

    You'll need to waterproof it. Self fusing silicone tape from Home Depot works well.

    I just make my own adapters with some heat shrink tubing. It works well to make plugs water-resistant, well known on the DIY forum.

    I agree with TiGeo,

    The one it comes with is fine. Cut the velcro straps off, add 3 zip ties and you're done. And the further you mount it up front, the less it sticks up above your head to catch on tree and such.












    Go Pro mount does look nice though.

    Good solution. I like the light to sit lower down and more forward, so it doesn't catch on stuff.
    The GoPro mount also sinks a fair bit of heat.

    The heat sinking is definitely nice. I would love a little more heatsinking since this light generates some serious heat with so little surface area. But if you look at the over all height of the gopro mount, it really isn't that much lower profile than the standard.

    Allow me to barrow Smoke&Laser image here:




    I would guess that it's only a couple millimeters lower in the upright position and maybe a little more in the forward position. If I were to mount the standard one all the way forward on to the visor as he did, it too would sit lower than the top of the helmet. I just wanted it a little more secure than double stick tape.

    Also, I advise if you're going to helmet mount it, get the 10 degree lenses from LEDDNA. Much better throw! Although be careful, the head of the two front screws strip very easily.

    Mine sits lower than that- Smoke used the tall mount for the one that faces backwards and his mount sticks out to the back more.

    I'll play with the 10 degree lenses- I have some in stock, but it looks pretty narrow with the optics provided.

    It might be possible to stick some heat sink on the top of the light if need be.

    Using commercial mounts will only get one so far in how low a light can go. The GoPro mount is pretty big and tall, particularly the reverse one in Smoke's last picture. I don't use a GoPro mount on my helmet light for that reason.

    Vanc's is the lowest ever. Most of my DIY lights have a custom mount that sits very low,


    but I'm spec-ing Gopro mounts for my friends now as they're easy to find and work well on helmet, bars and headbands.

    I'll see if I can get a shot of the Gemini clone mounted up.

    I placed the light to forward as this is the only place that is flat on my lid.
    Could have the light low down but the light glare shines right into my eyes.

    One solution would to be turn the Go pro clip round slid in from top to bottom.



    A week on and still not sorted out new lens make more of a spot.

    Some people don't need to worry about whether the light sits high or not.

    In my area, many trails have trees with low branches. When the rainy season sets in those branches often droop lower and become light catchers. I caught my old NR halogen light on a branch many years ago and have worked for low mounting ever since.

    Sorry to revive this thread, but very interested in this light. The Wallbuys is out of stock, so looking at the Lightmalls one. It looks like the Wallbuys one has 60 degree lenses stock and not sure about the Lightmalls one.

    I am looking for a great set up for helmet and bar. Would it make sense to buy 2 of these lights and get 2 10 degree lenses for the helmet and 2 60 degree lenses for the bars to make a perfect set up and be cost effective? Also looking at a SSX2 for the helmet if that would give better throw and spot. Obviously want as much flood as possible on the bars. So many choices, but I love the size and look of this light.

    If that works, I would probably use stock batteries for now and then upgrade down the road. Or, I guess I could buy the light only for $14 less and buy a better battery set up for starters for close to the same price? Thanks for any input.

    I wouldn't worry about the lenses.

    Buy two of the Lightmalls units with 6-cell batteries - you'll have spare/redundancy. I run one each on handlebar and helmet for off road riding. Just one on the handlebar for road.

    Start with the included batteries, upgrade later if you find you need to. My .02.

    I had a look about for another one seems they gone up alot.

    They still on DX but did take time to get to me three months. Could be just unlucky.

    Some on Ali Express I think the site is but I never used them before.

    I don't see the Yinding on lightmail! Not found by search.

    The 60 degree is in a typo; they look to be the same as the Duo...16 degrees.

    So would the stock be better for the helmet and then put 2 60 degree lenses in the other one for the bar for better flood?

    The stock light works fine as a bar light. I tried the 45 degree lenses from LEDDNA and didn't notice much difference to be honest.

    Thanks TiGeo. I saw on a thread I believe you have the SSX2 on your helmet. Would that be a better combination? I love the size of these lights, but also want to have the best (inexpensive) combo I can find. Maybe there should be a Best Clone set up under $100 thread! Would be fun to see the different combinations people are using on their bar and helmet.

    Yes, I have a SSX2 for the helmet in my budg-o setup. It is a nice spot for the helmet and works well with the Yinding on the bar. The issue I had with this setup is that the color of the LEDs is different; the SSX2 is bluer/whiter than the Yinding which is more "warm". I think the Yindings out now are not the same LED and will look more like the SSX2.

    Just wondering; Since you own both the Gemini Duo and the Yinding, is there a noticeable difference between the two ? ( other than price of course )

    Sounds good. I like the form factor of the Yinding better, was hoping with spot lenses on the helmet and floods on the bars, it would be a great set up. So if I get the SSX2 on helmet and Yinding on the bars, as long as both have the XM-L2's, everything should match ok? Sounds like the SSX2 will be a better spot on the helmet. If it is negligible, I would go with 2 Yindings.

    Not really that I can tell Cat except for the color. Keep in mind I have the "good" version of the Yinding.

    Does the Gemini have custom power setting guess only come into play realy when racing?

    I did had a look again at Gloworm again but sadly it's cost to much.

    I have to look again Gemini vs Gloworm vs Yinding.

    WHOA! This just in - KD is now carrying a head only Duo clone! (I don't think this has been mentioned and I do believe KD just added it within 24 hours.) I'm jumping on it as I've been sitting on placing a KD order for some parts anyway.

    But this isn't the "good" version..just so you know. May not have a good seal on the cable, maybe no o-ring, and likely a crappier mount.

    Right, I see that. I'm willing to work with it. I consider all these cheap lights "mod hosts". I am loosing track of which ones were good or bad. I was waffling on the Lightmalls clone (due to the programmable driver) but remember someone posted it wasn't good for some reason.

    I don't think there even is a "good" version available any more, is there?

    EDIT - I see that mk96 mentioned KD having a duo clone in post 683, though I don't remember anyone posting a link.

    dawgman25 - I wouldn't use two 60 degree lenses as they spread the light too much. I ran a 60 and 45 and it didn't have enough throw. I replaced the 60 with a 10 and now it has a nice mix of flood up close and throw down the trail. I run a 'good' Yinding on my helmet with the 15-20 (nobody knows for sure) lens and it makes a good pairing with the bar light. I also replaced the LED's to match the warmer tint of the good version as it is quite annoying having different colored lights.

    Thanks, that helps a lot. So if I get a SSX2 for the helmet, I want to get the newer version XM-L2 and get a Yinding clone with the same so the colors are correct? Can't decide if I want 2 Yinding clones with different lenses or an SSX2 on the helmet for more throw. It seems the XM-L2 is the best LED to get right now?

    My long term goal is to get a great Gloworm set up, but I want to get a good cheap set up for now to make sure I use them enough to justify the bigger expense. Then I can use the cheap version for friends, backup, etc.

    Definately agree on the colors..annoying.

    Especially don't use the frosted 45s or 60s, they knock the light down to nothing. Currently using two clear 45s on the bar Yinding and two 10/15s on the helmet Yinding, nice combo. Bought both at the same time and got 2 good ones in the warmer tint.
