    Good question. Without knowing more about how much power the SS X2 is using my guess is that if you are running the lamp on high you should get about 1.25 to 1.5 hrs. run time with a very good two cell set-up. The lamp will probably start to dim slightly at the 1hr mark and continue until the lamp cuts off the power.

    If you run the medium setting you should get over two hours without any problems. When using two cell set-ups it is always a good idea to only run the amount of light that is needed. Now if you are using a "cell holder" you can always carry a couple spare cells in your bag and have no need to worry about such things.

    SolarStorm/FandyFire X2

    I might order a couple of cell holders and power cables and just make 2 units from some 3400 batteries, then I can just insulate the holders and carry a spare. It's unlikely that I will need much more than an hour so that will probably work well.
    I'll have a look on the weekend and work out what I need but worth a try with one of those X2 as should make a very light weight helmet setup.

    We know it's Chinese lumens. Apparently it's also Chinese mAh. The advert says a 6600 battery -- Yea - Right -- At that price?

    Oh look - they're throwing in a $2.00 tail light. Are they adding the mAh from the 2 x AAA batteries to get the 6600? Are the AAA batteries even included?

    Sold in AU dollars - shipped from China. Overrated specs. Return policy is 30 days from date of order - 7 days from receipt. Looks like a typical Fleabay seller. Like Cat always says - read the fine print carefully.

    Bought at FastTech (known retailer with good track record & reasonably accurate specs) using the BLF discount code would be $40.59.

    Its probably better to buy the light alone and the buy a holder + samsung 2600/panasonic 2900-3100-3400 cells for it.
    8 4V 6600mAh Aluminum Shell Rechargeable Battery FOR XM L T6 LED Bike Headlight | eBay btw there is a holder for $16 shipped.

    How are thee battery holders working out for those who have tried them? Are people using an external charger or leaving the cells in the case and charging them?

    I think most people know about the lumen and battery over rating issues. If the lamp is shipped from China you might get a decent battery. When I say decent I mean something around 3000 or > ( real )mah.
    I just ordered an X2 as well from another Chinese website and it too will likely have a crap battery. I'll have a better return guarantee but have to wait 16 days to get it. Personally I'm not worried about the battery as I have better compatible batteries standing by.

    @ leighaus ; Just make sure that when your lamp arrives that you do a run time test ( with fan ) to make sure all is good. ( If you get 2-2.5 hrs on high than you have an acceptable battery IMO ) No promises though on how long these batteries will hold up. Not unusual for a crap battery to last less than a year. If any immediate problems contact the seller ASAP and file a complaint with the e-smay people ASAP.

    I received the SSX2 yesterday and it's the 8.4V 4 mode and black shrink wrapped batts. Haven't checked the duration of the battery as I just received two new batterys from Xeccon which were really quick in arrival and great service thanks to Leonard. Definitely a big difference in quality of the cells and workmanship between xeccon and the supplied batts with the ultrafire (clone) and X2. I noticed a difference between the two LED's in the SSX2 and i'm hoping its not a defect but that maybe the optics are different in each one to provide more spread or spot?? can anyone clarify that or should they be identical? Have i maybe got two different LED's?

    has anyone swapped the optics if that is my issue? this lamp get way hotter than the ultrafire quad I bought.

    Upset

    So i had a better look and found that there is epoxy type stuff on the lense (is this heat sink goo?) and that is what reduced the light output. Some has discoloured as you can see, i'm assuming from heat....?

    Contacted seller but not holding much hope. You can see that from the pic the top screw just sheared off leaving the thread stuck in without much force at all. So I tried to clean the epoxy off but succeeded in chipping the clear lense material over the led and now the lamp doesn't work at all. dow!!!

    Could i buy a replacement LED and solder it in as a replacement and if i can what else could i improve while i'm in there?

    Wow! I'm amazed you got everything apart! Was it easy to disassemble?

    Anyway, I was going to say that it you can careful remove the glue from the emitter dome ( without scratching or removing the dome ) you might get full output. Sadly, welcome to the world of Chinese quality control.

    Since you got it all apart looks like it might be easy to mod.

    Easy to get apart aside from the screw snapping just a phillips head screwdriver and small pliers - 5 min max
    I sent pic of beams but i don't want to send the internal pic to the supplier in case he just says i stuffed it by taking it apart when that isn't the case.

    What are your thoughts on the discolouration of the goo.?
    is it possible that the goo made its way onto the globe after i started using it or is it more likely to have been that way when produced by sloppy workmanship.
    I'd like to send him the pic of the lens with crap all over it to prove my point.

    The discoloration is probably from the heat. I figure the goo was there from the git-go. They might have used it to help keep the reflector from moving, hard to know for sure but very obviously they used too much. Since it is contacting the emitter dome that is not good for two reasons, one...it blocks light, two...it holds heat close to the dome. If not removed the emitter will eventually discolor or just burn out. The sooner the stuff is removed from the dome the better.

    I'll agree with Cat that the goo was there from sloppy assembly. It is very likely that replacing the LED will get it going again. When the dome was damaged in attempting to remove the contamination it probably broke one of the bond wires to the die. That's not repairable. If the reflector is contaminated it may be hard to clean without damage. Often the reflective coating is soft and thin and easily damaged. Just rubbing with a q-tip soaked in alcohol will scratch the coating and sometimes even remove it. Finding a suitable (ie. exact) repacement may be difficult.

    The regular X2 use xm-l? Is that right? Here's one (or clone) that uses xm-l2
    Aliexpress.com : Buy Free shipping SolarStorm 2x CREE XM L2 T6 3B LED Bicycle bike HeadLight Headlamp Light 8000mAh battery pack from Reliable bikelight suppliers on Shenzhen Great Wall Technology Co., Ltd.

    It's also more expensive at $57.49. Gotta love the dirty alley beamshot. Looks pretty good though.

    The circuit boards are white, in that new version of the X2. That IS the signature of an XM-L2. Nice pix of the guts too. The retailer seems to know the things we want to see.

    Same seller as the "Fixed D-99" that Kir posted. Same brightness & color bins too.

    I wonder if that seller is specifying L2s to its suppliers, or if the L2 is just becoming much more widely used? Hope to see other sellers with them soon (FastTech are you listening?)

    Yes, I noticed the same things. Also the emitters are mounted on copper cores...which is also a big plus. If you switch between the the two links ( "Convoli" D99 clone and X2 clone ) both show a photo beam shot done in the same alley. The X2 version looks brighter and has more spill.

    I have to wonder though if they are both using the same driver. On the D99 clone the mid-level output list 30%. That's not particularly good because I doubt any of these lamps are really driving the lamp as hard as they could.

    Anyway, a real shame because the Convoli D99's are really nice looking lamps. All things considered, the Convoli X2 clone looks like it has better output. If you are looking for a bar lamp with a warmer tint ( not super warm but medium warm ) then you should really like these. The ad's say these emitters are in the 5000K range, very much like the torch drop-in I have. Still, some people who like a brighter white would probably prefer the Xm-L U2's. There is a brighter bin Xm-L2 ( in the 6500K range ). I've not seen one of those yet but I bet they are awesome.

    Dang it, I really would like to see one of these Convoli X2's in person. Unfortunately I'm not Kir. I can only affford to buy so many throw away toys.

    P.S. I also expect to see more vendors selling these real soon. This is probably why the other lamps are dropping in price. Right now the market is over-saturated with X2 clones. Other than the cheap-o batteries they come with these lamps are super deals.

    Definately not the same driver. Look at the boards in the two adverts. The X2 driver is way more complex.

    In Kir's original look at the X2 (approx calcs), Low=21% - Med=65%.

    If (and I know it's a big IF) they only swapped the LEDs & didn't change the driver, the X2 - XM-L2 T6 3B version, should have pretty good mode spacing.

    I've got the original version and found all the modes very useable. Even on Low people (like security guards) stop me and ask about it because it's so bright. I've even gotten envious looks from the cops on bikes.

    In June when the flood in Calgary took out power to a large chunk of downtown and other parts of the city, I was wandering through the blackout area. (Shed a tear for my car submerged to 4 inches up the back of the seats.) With 100,000 people evacuated (across all the various flooded & blacked out neighbourhoods), the area was crawling with endlessly circling bike cops. I thought how pittiful their lights looked in comparison to mine.

    I love that they say is a 8000 mAh battery pack. I'm guessing that it runs at 7.4 volts. What single 18650 is 4000 mAhs.

    Very good. Since I have a U2 version of the X2 on order I'm really hoping that one; it is as usable as I think it is and two; that it is easy to mod.

    @ ironbrewer: Yeah, I know what you mean. BS lumen claims and BS battery claims...what are ya going do? For the folks that know the limitations of emitters and batteries it's not really a big issue but you have to feel sorry for others who don't know as much.

    Great price. It does have three modes (Low Mid High), unlike the Ali light head only.

    In reading the Light Malls add one thing jumped out at me. It says the flash mode is SOS. The one I have is a slow flash. That might imply a different driver or a clone.

    I did check with LightMalls online "live support." The support rep said it was a slow flash not SOS. He has corrected the specifications on their web page.

    Yes I think so, the price is unbeatable If the specs are with slow flash perhaps i would go for 2 of the and mod it with wide angle lense, xm-l2 u2 bins and slightly change the current sense resistor to give it more juice

    They must have fixed the ad. Now says, "slow flash". The key here is that the lamp has the original Solorstorm markings. Always a good sign it is like the originals. If I had seen this ad I would have ordered from light malls and saved $10. If I get a decent battery than I made out. We'll see. Great link though for the "light head only". Hard to beat that price.

    You need these batteries to fit in that battery pack.
    Also these batteries have to be discharged to 2.7v to get full capacity out of them, not sure it that battery pack protection circuit will allow that...will test that a bit later.
    (beginner question alert)

    So I got the battery pack, the batteries, and have an iMAX B6 charger. The pack has no balancing cable, just a magicshine style cable.

    I assume the idea isn't to just throw the NCR18650Bs into the pack and just charge away, but some pre-work is needed to get the most out of the new pack.

    Do I need some other kind of case to put these batteries in to get them discharged to 2.7v and/or otherwise "balanced" properly before use? It doesn't appear the pack has the necessary connections/smarts:

    4 x 18650 Battery Set for Bicycle Light-in Charger from Consumer Electronics on Aliexpress.com

    Sorry this might have been better posted in the battery thread... but maybe helps others putting this same pack together for the Solarstorm-style lights.

    gopherhocke, just fully charge all of your new cells one-by-one before putting them to the battery box. You don't need to discharge them first. But you may want to do that in order to measure their actual capacity.

    2.7V mentioned by Kir is just lower discharge voltage allowed for these cells, but many protection PCBs may disconnect the cell around 3.0V level, thus reducing available capacity.

    And why is that, got bad batch with low capacity blue batteries?

    You, like most people here (and me actually before I started my project with bike lights reviews) don't understand how this system works.
    These sellers on aliexpress - they're NOT the manufacturers, they're just that - sellers. They (well, most of them - there are some expections) will buy batches of lights from different factories and will sell what they can find at cheapest price.
    What's even worse is that the factories are the same, they will make lights from the stuff that they have in hand and they usually don't care about quality.
    Basically buying all these cheap lights is always a lottery and you can't predict what you will get.

    I bought about 8 SSX2s from Shenzhen EF Lighting Sci&Tech Co., Ltd and already got _3_ different versions with different drivers, different batteries, even different cardboard boxes. Two batches were good, one batch had bad batteries. I don't know about the drivers and current draw/current on leds, haven't measured all this stuff yet - but they all work fine.
    I'll post SSX2 review soon after receiving a few more samples and I'll compare all the different versions there.

    And btw - this is also why its pointless to read any descriptions, talk about advertised "U2 leds", "sos or strobe", battery capacities and all that stuff. You will get what you will get and it may not be what you expected or what was written in store's page or aliexpress listing.
    This is how it works with cheap chinese lights, unfortunately

    EDIT: Read this thread on fasttech, especially replies by geek (one of owners of the site) about consistency and quality control:
    https://www.fasttech.com/forums/feed...not-being-addr
    Its not about bike lights, but its basically the same and can be applied to any cheap chinese mass produced stuff.

    Now it is about 80$ min. order 3 pcs

    Why? Do you mean the lightmalls seller or the vendor that produces them?

    What are your thoughts on the discolouration of the goo.?
    is it possible that the goo made its way onto the globe after i started using it or is it more likely to have been that way when produced by sloppy workmanship.
    I'd like to send him the pic of the lens with crap all over it to prove my point.
    Just took a look on previous page.
    You're not supposed to be able to remove led's pill like this!
    http://fcdn.mtbr.com/attachments/lig...-50-04_921.jpg
    This pill should be press-fitted/glued to the case, it provides thermal path for heat from led to the case.
    Your "goo" is just a melted plastic spacer like this one:
    $1.37 Insulation Gaskets for Cree XM-L T6 LED Emitters (10-Pack) 10-pack - 7mm opening / 16mm diameter / 0.5mm thickness / insulation & location function at FastTech - Worldwide Free Shipping

    Led's pill probably got loose in your light (manufacturing defect), reflector alone couldn't push it to the case hard enough and the led overheated while melting this plastic spacer. You can replace the led but you should somehow glue/press pill into case.
    Also don't run this light on high without active air cooling (switch to low when not moving on bike) - it has a very, very lightweight case and overheats very easily. I don't like the look of the 2nd led in your light, looks like spacer is melted there too.


    And about this light from ali - its just a SSX2 with new leds, nothing special about it. If you have a soldering iron and a $10 to buy 2 of these:
    $4.05 Cree XM-L2 T6-3B 10W 1100LM 5000-5200K Neutral White LED Emitter on 16mm Base Plate at FastTech - Worldwide Free Shipping
    you can make it yourself, and much cheaper than $82.
    Also its convoy, not convoli

    They now appear to be $82.13. Must have gotten popular enough to raise the price over the last few days…

    Kir, thanks for all that feed back. Hard to believe that a thermal spacing gasket could melt like that but I suppose it shouldn't surprise me. Possibly they substituted a cheaper gasket that couldn't handle the heat. The D99 I had used hard plastic O-rings as spacers, nothing like the big ones you linked to I'm glad to say.

    I agree with your other comments as well. You never know when parts are going to substituted out. This doesn't mean you will get something that won't work but there might be unexpected changes that you might not like.

    A while back I ordered a lamp ( not a X2 ) that was supposed to be 3-modes and got one that only had two. Than again when a driver is switched out there is no way to know unless you know what was originally suppose to be in the lamp.

    All said, when this happens it usually happens to products that have suddenly gotten popular and the stock of the item quickly runs out. This probably brings about a rush to restore stock and when stock parts run out they look for quick sub-standard replacements ( rather than the OEM parts originally used ) At least this is my opinion on the subject.

    I have exactly the same experience with buying supposedly-identical lights from East. You'll never know what you get until you'll disassemble & check it...

    Quick update, 3rd version of SSX2 from Shenzhen EF Lighting.
    Differences: screws are now cross/philips type, previous versions had hex screws. Driver pcb is now green (it was black before) and soldering looks worse.
    Black shrinkwrapped batteries again, but this time with 2700mAh capacity (1st batch had 3000-3800mAh batteries, 2nd had blue batteries with ~1700mAh capacity).
    Waiting for more samples from another sellers...

    I was probably both rash and ignorant of the process over there in my 'don't buy an light from these guys' so thanks for setting me straight. As you can imagine I'm just frustrated because of the workmanship and service. I know I know, get what you pay for etc and I did expect to buy a new battery for it but I hoped the lamp would at least arrive working correctly and maybe last a year.
    I'm realistic and on a very tight budget so I went out on a limb and got burned. Nothing more frustrating than trying to explain what went wrong to someone with very poor English and me with no chinese. or maybe they understand perfectly!

    I'll look into soldering in a new pill, in your opinion Kir would the LED you listed be the best option for replacement. Also what's the best thing for connecting the pill to the body? jb weld would conduct heat well as it is epoxy with metal filings in it and is heat resistant. Anything else I should do to improve it while I'm in there?

    On the heat issue, I didn't run the X2 stationary only the ultrafire x4 which hardly heats up at all in comparison. The X2 has heat protection (drops down when hot) as well.

    anyway lessons learned

    Kir listed an XM-L2 - so you'd probably change them both to be correct. The best is to apply some thermal grease e.g. arctic silver or something similiar.

    Would I epoxy the pill to hold it in and thermal grease the edges? how would I hold it in firm to prevent the same issue reoccurring. and do I need the thermal gasket that melted on mine?
    Kirs' listing was 16mm, I just measured the pill and it's 20mm.

    I would buy 20mm (if the 20mm is original, 16mm may be too small), if you want to change just one, buy some 20mm XM-L U2 (fasttech, lightmalls, dx, kd, ... whatever and where ever you find the right one). Since I do not have my lights yet, I cannot say how to fix them. Epoxy or solder at 2-3 points may be OK with some thermal grease. I am not sure but you can use instead of melting gasket high temperature (300 degree Celsius) silicone.

    that is the one that melted probably, but as I said, you can go to high temp silicone. There are also some emitters at CNQG site .

    Just got one of these. Black battery pack, cannnot say anything about capacity yet. The lamp quality seems good, here are my current draw measurements (external PSU, stabilized 8.4V):

    max mode: 2.13 A (2130 mA),
    mid mode: .85 A (850 mA), fluctuates from 0.8 to 0.9
    min mode: .03A (30 ma), fluctuates from 0.025 to 0.035

    So there is plenty of light in max mode, lamp is getting very hot quickly.

    Nice one, and the draw at 7.4V - regular li-ion/-pol working voltage? Is the min mode like parking lights = .03A too low to see anything ?

    WOO WHOO! Postman came knocking today. I now have my SS X2 clone in my hot little hands. A quick run-through with the light shining down my hallway looks VERY favorable. Output on all three steady levels MORE than meets my expectations. The driver must really be pumping the juice, this thing gets hot fast.

    Anyway, mine was purchased from Manafont. I think it took about 10-12 days to get to me. Not bad. Usually takes 16 days. No time for more details I have to get to work. Hopefully I'll get a chance tonight to shine it around outside if I can fine a nice dark spot. I have a feeling that it is really going to have a nice usable beam pattern.

    For 7.4V it draws 1.35A. Now this is highly subjective, but mid mode is like 50% and min mode something like 15-20% (there is some useful amount of light).
