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

    Yes, on each cell. On the whole pack it would be really bad.

    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.

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

    U2 is the updated version of T6. It is more bright than T6

    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.

    ^^^read. But with that said...

    Yes...mine I got from Wallbuys has the XML2. Mounting-wise..just a standard Magicshine helmet mount will work.

    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.

    The one that comes with the light is fine; just need to cut off the silly rock-climber strap and get a velcro strap..bam! I posted a pic of this at one point.

    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.

    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.
    Note- if you're not logged in, you'll see links to "bar mount" and "GoPro adapter" which are fake and automatically added somehow.

    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.
