CREE Flashlight 🔦 How to Fix Frequent Problems

[@asncloud]

Your 13 years old video fixed my problem in 2024, My wuben TO40R not working, after watching your video i opened tailcap spring and then i extended it and the my problem was solved. Thank you.

[@motorbiking18650]

made back in the day, when KZbin was a place for videos that helped people fix things.

[@talldave1000]

I put tape around the battery and snugged down the switch ring and every mode works now. Thanks for the video!!!

[@motorbiking18650]

glad it was helful

[@press4time]

Thank you, thank you, thank you. I was starting to feel hopeless about fixing my VG-10s. I bought my flashlight on Amazon and it never worked. I held on to the flashlight for months and gave the flashlight and sender a bad review. I had spent countless hours going over videos on how to correct the problem of getting my flashlight to turn on. You are the only that suggested using elctrical tape. Two pieces of electrical tape fixed my problem. You're the real MVP.

[@lieu14]

I have a 501 that stopped working, it would only work if u pressed the button down slightly just at the right pressure which was pointless because it was impossible to stay at the right pressure to keep it on. I had given up on it and forgot about it for a year then I dug it up and found your video and all I had to do was just tighten the back cap, thank you so much!!!!

[@tubefishing6969]

Yep, nailed it! The end cap screw was the issue!!! Thanks so much!!!

[@kizzyaggots1]

Thanks mate you saved my 501, the remedy was very simple, I also use recycled batteries and now i can find my way to the dunny at night

[@motorbiking18650]

glad it helped

[@MrWeb49]

I just bought a A1 wowtac And it was DOA arriving at my house Watching your video I fixed it my turn in those 2 little holes tail cap was really loose I tighten it up like you said and It fixed my light Thanks so much

[@motorbiking18650]

glad it worked

[@patobrien5307]

Thanks. I've now got me a quiet and wiggle-free little flashlight, along with some Cree basics to help keep them alive and well. I appreciate the time spent and thoroughness to patiently explain and show us how to keep 'em alive.

[@victoranchipolovsky714]

Thank you! I was so confused when I got new batteries and my light still didn’t work. The first trick you showed is what got it working again.

[@xotoxpv]

I had the shake problem. At first I tried to put some aluminium foil to the battery ends. There was some improvement, but basically the problem remained. After your video I've put a piece of spring from pen. Now it works perfectly no matter how hard I shake it. Thanks

[@cmddelete2169]

Was about to fork out for an Exposure Joystick after my Ultra(mis)fire died. Watched your vid and saved £112. Brilliant, thank you.

[@motorbiking18650]

+Cmd Delete and you've probably got a brighter light too ;)

[@cmddelete2169]

Yeah, aside from the quirks you listed, it's actually a better light.

[@zealotguy]

gotta let you know, I didn't know the switch came apart more. I took it open with a screw like you showed and discover a short circuit that was preventing the mode from resetting when the torch was shut off for several seconds. thanks, man.

[@peterjuriss463]

Thank you for the video. Cree Unique Fire didn't go. Was going to order a new bulb set, but saw your video and tightened the plate holding the button with a small screwdriver. Simple fix that I hadn't tried. Goes well now!

[@17837]

Nicely done .. articulate, intelligible, no grating background noise, helpful tips .. thanks !

[@Knifeguyyy]

I have a custom light that was coming on at random, and also dimming all the time even with full charge. 18650 by the way. I had pretty much given up on it, and ordered an ultrafire 20 minutes ago to use with the three batteries and charger I've got now. Well searching for ultrafire vids and found you,,, I just tightened up the internals on the tail cap as you show here,,,,, my custom is fixed!! I can't believe it was so simple, and I can't thank you enough!!

[@motorbiking18650]

Glad to help, shame you didn't find in before replacing it ;-)

[@thiagotbm]

its helps me a lot! my 501b doesnt work, so i did what you suggest and problem fixed. thanks

[@motorbiking18650]

No problem glad it helped

[@williammontgomery6132]

Thanks bro just did the needle nose plier tightening,working.Tried just one side tight with screwdriver first didn’t work. Needle nose happening

[@grst50]

I bought the ultra fire wf 501 b about a year ago. The other day I needed it and it wouldn't come on. I checked the battery with a voltmeter and it showed good. I thought I was going to have to get a new "bulb" but after watching your video I tightened the switch like you showed and it worked! Thanks so much for showing!

[@afsglmale]

Thanks I found the problem was a loose tail cap but was not sure how to tighten for the ground path, seeing the needle nose pliers was the clue I needed, tighten up the with the two points of the tail cap and now working good

[@rogerhall7235]

Thank you very much. I almost threw my flashlight away thinking it was a lost cause. I love a happy ending.

[@Lhartman]

Thank you for this video. I was having a problem with intermittent on/off when the light was turned on. Eventually it wouldn't even turn on unless I pushed the button left or right while it was on and found out I had to tighten up the retainer ring that has the two dimples on the back cap. The part at 2:20 in you video is what fixed my problem. Guess they just sent it to me loose from the factory.

[@OldDadProductions]

I got an Ultrafire torch today with two Ultrafire batteries. The torch was flickering when shaken or moved. Your video is great, but none of your suggestions fixed my problem. I finally tried the second battery and sure it enough, it worked great!! I then took both batteries and shook them and found that the dodgy one has something a bit loose inside it. To cut a long story short, if all this fails, it may well be the battery thats dodgy even if its new!

[@AClarke2007]

Inspirational confidence is what we all need!

[@bmwnasher]

My click switch was loose, the plate with two holes needed tightening, bad quality control, not bad torches, cheers for posting this video,

[@michaelrich5501]

I just mended mini that was intermittently working going bright to dim to sos then no light so I soldered copper branded wire from top to bottom of each spring front and back and now it works as it should.

[@frankyvee1]

Thnx to this awesome video I was able to fix my Cree XML-16. This torch uses a 18650 battery = 3000 mah battery. I had a loose positive wire on the driver board. I pulled out the old soldering iron and got fixed. Looks like the wires being used on this torch are way too small to handle the current. I put some heat shrink around as well to give it some strength.

[@barrelwolf]

Thank you, I was about to buy my partner a new light but after watching this video it only took me 5 minutes to fix the light.

[@GraveyardThought]

It was right in front of my eyes, the remedy! Thank you for saving me much more frustration :).

[@mrbluenun]

That explained the physical difference between the two type unprotected and protected and thought this slight indent was the cell having protection used? In which case can the same simple test with a wire round the disassembled light-emitter and long enough to touch the negative end of a battery? Absolutely EVERYTHING is a load of great Advice, (see I bet you thought I was going to say something nasty) simple to follow and understandable, thank you for that. Take care. mrbluenun

[@MrKoronasOther]

Thanks for the video helped me solve my issue of it switching mode. Final result was adding packing around the battery and resoldering the spring to the driver housing(looked like a bad solder joint in the first place)

[@stubbostubbs]

Cheers for your help. Its got me stymied. Its a single cell. Worked brill at first. Used the charger that came with it. No joy after recharging from Red to green. Suspected the cheapo battery cos the torch itself is good quality. Got 2 new batteries (and a new charger) , charged them both up. Put one in the torch and ZIP.. Yet if I place 2 x 1/2 sized cam batteries in there it works, albeit dully but it does show therefore that the leds (3) are working....... Pass me that razor blade.!

[@dstke]

Awesome! Tightened up the rear cap and now working again. Thanks.

[@Sydpg]

I was so close to bin the ultrafire torches... got them back in working condition again! Thanks man...

[@renod42]

Thanks. Dropped mine and it stopped working. Small washer on the negative end “fixed” it.

[@surenbono6063]

..i had issues on similar new flashlight...got it working by removing the 18650 protective o-ring near the positive terminal which is negative ..the LED circuit should have direct contact on both terminal before the switching happens on its bottom....the gap between this terminals are so close ...normally covered by shrink tube or similar to prevent oxidation (tenderites) and batt short...point that as well..

[@awesomein360tiagowolf4]

Thanks for the vid. I dissassembled my mtb cree CPG350 but my issue is different. Its saying the cell is full but it doesn't light up unless it's connect via usb/ charger... Any way we could reset it?

[@rsdevarapalli]

Thank you much for your video, I was able to fix the problem in Tail Cap. That was a Productive outcome. Your video will find a much wider reach 😊

[@motorbiking18650]

Thank you all so much for your +ive comments. I feel like such a geeky/nerd :)

[@Participant616]

Tightening the rear cap sorted me out, though I used my multimeter probes and broke them in the process :p. Great vid.

[@RealButcher]

Thanks man... I did find the fault... broken wire, under the led... the red one.. got to solder it and presto.

[@daniellurkin]

legend, just fixed two of my l.e.d. torches. thanks man.

[@newhuskytwenty]

@motorbiking No, I haven`t any MC-E drop-in, I just would like to know if pulling for example 2,8Ah would be as bright as my XM-L drop-in. A black hole in the middle wouldn't disturbe me outdoors

[@richardhealy8911]

Ok thanks I'll try it. That said the cells I use are quite a good fit as in they don't rattle around much. But I'll try it and see how I get on

[@duke8389]

How can I test the led in a floodlight flashlight? Stanley SL10LEDSL I have pictures of it opened up if that helps.

[@Oliver_Abbie3]

I have a XML T6 flashlight and it have stopped working. I see that you've included this video for the flashlight too, but my tail cap is sealed with tape instead of the two dots to check if its loose. I also can't take out the chip. Is there anyway you can do a video on how to take it apart and how to make it stay on one mode instead of clicking several times to get to the same mode?

[@motorbiking18650]

Remove the tail cap and use a piece of wire to connect the body tube to the -ive of the cell to check the light works. you might need to pack the tail out with some washers if you cannot tighten the tail cap. I have no idea what an XM-L T6 light is as this just refers to the LED.

[@motorbiking18650]

What LED does it have and what current does it draw? You can then workout what upgrades are available. The simple option is to replace the drop in. The brightest option will be XML U2 or higher running at 2.5-3A, though at that current heat and run time will be a problem. As for batteries see my other video or google 18650.

[@motorbiking18650]

@sparkysteve73 This is usually a loose connection somewhere. You may need to peel the "paper" disc off the LED drop in and check the wires. Have you tried stripping it down to just battery and drop in as per the vid? If its still dim then, then its going to be a loose wire on the drop-in driver or LED. If you have an amp meter measure the current when connected. If its still drawing normal amps, then the LED is cooked. If the amps are low, its a connection issue.

[@Tanz32343]

Thank you, had a foxfury rook md1 flashlight that was faulting out. Thank you for the quick fix!

[@nursebank]

I bought one off the Internet.. I like these torches very bright it didn't work at first.. But after watching your video I managed to fix the problem thanks... I have a question tho how would I go on about upgrading the torch for max brightness?? And is it possible to get rechargeable batteries? batteries??

[@worrun1505]

I have an ultrafire not sure what model but it's about 7 inches long or so. To adjust the cone of the light the head is pulled up and down and it has become VERY hard to pull up and down, i cant get it apart any ideas?

[@motorbiking18650]

Sorry, no I try to avoid buying zoomable lights as they just reduce the output. Maybe some tf2 Teflon spray?

[@worrun1505]

@@motorbiking18650 thanks for the reply. turns out the rubber o-ring had doubled up on itself so instead of sliding up and down it was just distorting it :)

[@marcosguglielmetti]

Hello, very informative, thanks. I have an Imalent DT35 with 4 cree xhp 35 leds (2017) and 2 of them are flikering, blinking... I recently bought it used, but it had very little use, so it is like new.... sometimes a 3rd led will start ok at 80lm setting, but then will turn off at 1000lm or 5000lm settings. The 4th one will never turn on. Do you think is there some solution for it? (by the way, with just 2 leds working the amount of light is impressive!)

[@motorbiking18650]

I bought www.lightmalls.com/new-small-steel-cannon-flashlight-xhp50-led-3-6000lm-type-c-usb-rechargeable-aluminum-alloy-outdoor-led-glare-long-distance-searchlight for $30 and its really excellent. The multiple LED lights are hard to fix if the driver wiring is faulty.

[@mrbluenun]

Many thanks, One question, you said you are not using ‘protected cells ’bearing in mind I am pretty good ignoramus when it comes to ‘new’ tech things until I get used to them, I notice a small indent going round the end of the widest part of the battery where the indent is slightly smaller than the battery case, I thought and may have it wrong, that this meant the battery was a protected cell? I have only seen one channel and can’t recall which one it is as I type, that explained the

[@newhuskytwenty]

I got a pair of UF WF501B with XM-L drop-ins, one is the DX 5 modes and the other the famous MF 3 modes, which draws almost 3 Ah. I guess a MC-E drop-in would be less bright than them, am I right ?

[@motorbiking18650]

Is it 2x18650 cells? That will make it 8.4v input. I can't see a 3xt6 would be much use on a single cell. The problem can be caused by heat causing poor connections. Strip down to the drop in and the cell and see if it works. If not try some other power source 4.2v/8.4v depending on how many 18650s its meant to have. If it works then, then its about tightening every point. I've only had one LED fail like this and that was when I dropped it when it was hot.

[@MrGGPRI]

So where can we get parts ?? My x700 needs a LED cartridge-- it's dead.

[@mavspecialgirl1]

Thanks it worked on an Zefal bicycle flashlight and a Lux pro I found on sidewalk.

[@girirajrdx7277]

Hey there..i have some issues with my flashlight XHP70... Something with the pcb board. Light is illuminating when i touch poke the pcb at a specific area with a needle....i have no idea whats wrong or happening.. what should i do

[@motorbiking18650]

Have you tried connecting the pill directly to the cell with a piece of wire as shown? If its still coming on dim then you may have a connection issue in the driver, which will be harder to deal with. As a last result 2 rechargeable AAs or AAAs in series (giving 2.4v) connected briefly directly to the LED + - tabs can tell you if its a driver or LED issue. The LED should be OK direct up to about 3.2-3.5v subject to fv limit of the LED (e.g. XM-L - is around 3.3v)

[@ervinandreiaranador8683]

I unscrew the head and a little spring and a ball came out. what should I do?

[@GRR7634]

Did you have a chance to figure this out? Same thing happened to mine. I can't figure out where those parts go.

[@richardhealy8911]

Have sorted this now ( I hope!). I have circumnavigated the circuit board so that there is only 1 mode i.e. high. Can take a spare battery in case it starts to run low

[@harmoniousembodiment7203]

I tried your tip to connect coil in led light element to one end of battery with a wire and other end of wire to other end of battery, but it causes the battery to instantly smoke and burn?!

[@motorbiking18650]

`it sounds like you had some of the wire touching the cap by mistake.. Its often only paper/shrinkwrap that keeps the + and -ive apart

[@coastalheights3574]

I did the straight wire test and my led is very dim, any idea which driver and led for a replacement?

[@9P38lightning]

Any Ideas why mine stop cycling through the different modes... The torch work's but it won't change to different settings....

[@motorbiking18650]

If you can strip down to the drop in and the cell to test then this is the best place to start. If not remove the tail cap and use a piece of wire to make the connection. The mode switch just briefly breaks the connection, you can simulate by tapping the wire off and then on again. If that works you have a connection issue.

[@raph8505]

I just bought a cheap UV light, placed in fresh batteries and it didnt work. Though I got scammed or somthing but my gut told me to try all the batteries... Turns out 2/5 new batteries in the pack worked. I stil got scammed out of the batteries but at least the UV light works 😅

[@pointedspider]

You can also stretch the springs on both sides to solve this problem!

Dear friend I am using sky wolf eye model 3000lm torch but there is no any holes for unscrew switch cap how to repair that

[@stevendrew632]

Great video,although after trying all your advice the problem still remains.....the torch switches on as it should but is very very dim!!! Has the driver failed?

[@waha9014]

If your torchlight is flickering or goes no light when you drop, all you need to do is put a the smallest coin you can find and place it between the spring and end of the battery

[@hexterjazzbo]

Thanks for the viedo. I was able to fix my flashlight. Cree T8 had a switch that needed to be tightened.

[@elmariachiism]

Hey the modes in my Q5 stopped working, it's always on low now, and when I press the button and light flickers, so it's probably a bad connection. The rear cap doesn't have those small holes, it has a plastic cover. Can it be removed? Thanks!

[@VincentRodriguez007]

Extremely knowledgeable and through video on torch maintenance... Thanks!

[@ben2e]

Do you have a current favorite light ? I've bought Exposure lights but with the rate LED's improve, it's not a great investment. Most of the compact 18650 lights may not have a good beam pattern (for commuting).

[@motorbiking18650]

@YperionGraphic This is an odd one, I would conclude that your tail switch is too tight and that the half press to change mode is not actually opening the circuit. Either that or your driver is faulty. Strip to the bare drop in and Cell and see if you can get it to change mode.

[@gtramt1]

i have the same problem...i've got one smaller(battery inside 16340) and one bigger(battery inside 18650) ultafire torch. i've tighten all "screws" but problem persists... what to do?

[@Mentalduck87]

I just bought the XM-L T7 8500. I have charged the batteries to full and made sure they are in properly. I have figured out that a half press of the button changes it from 1 LED, to 3, to 7. However, for some reason the torch just keeps flashing and won't stay on a solid light. It is brand new and I have had it 2 days. Is there a reason for this or any way to fix it? I have searched the internet and and still come up with nothing. Seller hasn't replied yet.

[@Tyi_Live]

I have this flashlight (one similar) hooked up to a pressure switch. The flashlight ha modes u can cycle through, but I only want strobe. Every time I press the pressure switch, I have to press it 4 times to get it back to strobe for one use. Is this in the switch or the light that the problem is?

[@motorbiking18650]

The mode is on the Driver not the switch. The driver switches mode with a short disruption of power "The half press" Your trigger switch is causing the driver to switch mode. You could change the driver, but I'm not aware of any that can be set to single mode strobe. Most people want the remove the strobe mode.

[@DaveLennonCopeland]

Hey, motorbiking. My "Wilko Cree LED Bike Light Front High Intensity", got knocked off its mount and tumbled down the road, causing the LED to come off its little silvery square mount point. I just wondered if an unbonded LED can be easily fixed (by me, at home).

[@motorbiking18650]

Dave Lennon-Copeland thermal paste or high temperature silicon should work.

[@glytch5]

Good video man, a lot of us have these cheap ultrafire lights. Got to know this stuff.

[@stubbostubbs]

Very good video, well put together. I have a problem with a different type of torch and I wonder if you could help. It came from China I reckon via Hong Kong as a gift. Its a 3 led Cree and the wording on the body is CREE 3XT6 on one side and Angel-Fire A-11 on the other side. It worked great until it ran out whilst turned on. Now Zip after recharging. It. It works (dimly) if I put in 2x 3 v lithium cam btys but its very weak. ODD. Can you enlighten (groan) me mate? Any advice?. THANKS

[@ansdguy1]

Excellent video, however, my issue was not addressed. My newer model torch doesn't stay at the same level of brightness. It suddenly dims for a time, then becomes fully bright again. It takes about 10-20mseconds for this to occur. Do you have any thoughts on how to remedy this issue? Thank you very much, Ron

[@motorbiking18650]

It sounds like a poor connection which goes as the circuits heat up. Strip at tighten everything.

[@motorbiking18650]

@newhuskytwenty what Amps is the MC-E pulling? Actual output is very similar at the same amps, however the Xm-l is smaller so produced more lumen per mm, giving a brighter hotspot.

[@richardhealy8911]

Great video. Took my torch out last night for some rough stuff (cyclo cross) and found that every time I hit a bump that it would change modes i.e. from high to medium to flash/strobe. Is there any way to stop this? It's an Ultrafire 502b. Thanks

[@j03lturn3r]

I suffer with you bother. I did this to a Lumify x9 Basically the same. Bypass the control circuit 👍 kzbin.info/www/bejne/aGmqZ3iDp5psl6M

[@FreakzRitual]

I bought same one but got the longer one the same day I got it the very tip of the flash with the lens ended up falling off I couldnt find it how can I find the tip and lens to repair it

[@motorbiking18650]

You can get replacement lenses on ebay, but the bezel may be harder to find. To be honest given that you can replace them now for about $7 and the lens is going to cost you $2 you might as well get a new XM-L2 based one and then either use it for spares or use your old one for spares.

[@frack989]

I fixed my bike light with your first fix... Thanks... bye bye

[@complimentarycontemplation1873]

If you can’t get batteries out it’s probably corroded inside. You recommend greasing up ( not over greasing) the inside of battery container? This seems to be a pretty common occurrence. Batteries leaking? The inside is sealed off from the world so I can’t understand how else this would happen. Mines a g 32 and the warranty people were pretty good about exchanging it:). By the way when I suggest greasing It I’m talking about right out of the package.

[@motorbiking18650]

If you have corroded Li-ion cells they are best disposed of properly - 13w of power is a lot to go off

[@83VF750F]

Vary good video. Witch is brighter the XM-l or the MC-E? thanks Stephen

[@timwood70]

hey, mine just cycles though the modes. I have 2 CR123As in could that be the problem?

[@motorbiking18650]

@timwood70 It will likely be a loose connection somewhere, strip it down to the cells + the drop in and test. Personally I would use 18650s over Cr123 cells. If it still cycles when its just the raw drop-in then you have a soldering point loose.

[@SurvivalRox]

Your a very useful man to know thanks for posting ....and stay prepped

[@motorbiking18650]

usually the XM-L MC-E P bin is 962-1085 at 2.8A XM-L U3 bin is 1040-1105 3A but the most common bins are the T6 and the M or K bin which leaves the XM-L out in front. Plus the XM-L is much smaller, so the light per 2/mm is much higher.

[@motorbiking18650]

Strip it down to the drop in and the cell and test. If it works then you have a lose connection. Check the voltage of your cell, protected cells can sometimes fail to reset when the protection is triggered. Its very rare for the LED to fail, but it can happen. I say lose connection brought on by the heat of the unit. Might even need the solder checked on the driver.

[@YperionGraphic]

Greate solution that I also discover, before seeing this video and the issues and solutions are accurate. But till I found what causing the mulfaction, I lost the 5 mode operation (High, Mid, Low, Flash, SOS). Now the torch has only one mode (I believe the Mid). Is there any solution about this issue???

[@gester27]

amazing video. great stuff. i was just wondering. i have two of these but i couldnt tell, are they considered torch flashlights? mine seem to span out unlike others that have a beam? thanks.

[@recreate3204]

Hi I have a question and was hoping you'd be able to help, I just got an LED flashlight with a Cree XML T6 LED. The LED turns on but it's EXTREMELY dim when I turn it on, it's not the batteries or the button, any idea how to fix this? When I say extremely dim I mean like really dim I can look straight into the LED. It's like the LED is getting the least amount of power it will accept to turn on. It also will not switch between modes but I wouldn't really expect it to considering the LED seems like it isn't getting much power at all.

[@motorbiking18650]

yes. it sounds like a lose wire causing a micro arc. strip it down to cell and driver as per video and test. if it's bright then lose connection so tighten everything if still dim. duff driver.

[@recreate3204]

+motorbiking Okay I'll try that. I appreciate it. Mine isn't exactly like yours it has the led on a circular board with two wirea connecting it to the driver that sits in the tube. So should I use a soldering gun and take the wires off the board and connect the wires from the led to the battery?

[@motorbiking18650]

+Josh J No - your LED will go blue and die if you do that. The driver regulates the current, the reason I strip down cell and driver at 7:05 is to remove the switch from the circuit - have you tried this?

[@recreate3204]

Okay I appreciate the advice. No I haven't tried anything yet except pulling the flashlight apart to see If there we're any loose wires or anything.

[@johnwriter8300]

Hi, My Cree UltraFire TH-T60 spot just turned yellowish after I disassembled it for cleaning. Any thoughts?

[@motorbiking18650]

Its possible you got some dirt on the LED, however they tend to go blue when they are damaged. I would just check everything is tight or perhaps strip down to cell, wire and drop in as per the video and see if it looks different. Sometimes a lose connection can cause a kind of arc in pre-driver and this can affect resistance/current.

[@skulledmonte84]

I hope to get my cree 12x led five mode xm-l t 6 soon .i bought it used from eBay ,sellers says that it comes on but stays on strobe mode ,doesn't switch through the rest of the modes. What do you think is wrong with the light ??

[@motorbiking18650]

Any idea if it has a separate mode switch? My guess is a fault in the switch circuit, bypass the switch manually using a piece of wire and see if you can get the modes to change. you might need to strip it down to the driver to see.

[@YperionGraphic]

@motorbiking Well, my tail switch is ok, I check it with a friend’s one. So the malfunction is in the chip in the head. I can’t find how I could fix it, maybe a little “surgery” will help, but I’ll wait for the replacement and then I will try. Any additional help will be appreciated. Thanks

[@LAactor]

That's so great! How are you able to tell just by looking at the die if it's an XP-G or XM-L? I saw some comparisons side by side of T6's and U2's and L2's and I barely saw a difference..

[@motorbiking18650]

XPG is roundish and has 3 small bars, XML is slightly bigger and has 5, XM-L2 has a slightly honeycomb surface and no visable bars.

[@francisdirnhofer4423]

does these fixing methods work with ultrafire 502b
