Thread: uh-oh. L2T probs.

    Default uh-oh. L2T probs.

    my L2T has been holding up perfectly in the field untill now.

    went to ragap my plugs last night, and it was dark.

    pulled out the l2t and nothing. *click*click*click* WTF?

    so i put some fresh batteries in just off the charger.

    nothing.

    so i use the standard flashlight repair method of "percussive persuasion"
    and finally i get a flicker. then some really low low low output. enough to do plugs anyway...

    twisting the bezel to get to high causes it to flicker like crazy, but i cant get it to hold anything but "low" or "super-stoopid low"

    so today i cleaned it out with a q-tip and some cleaner, (filthy threads, took about 6 q-tips) and dressed the threads with some anti seize (nice and smooth now)

    now i can get normal low relaibly, but i have to monkey with it to get high, and most of the time it just flickers at several different brightnesses, and i really cant be on the job playing with a flashligt to get it to work for me properly.

    thoughts anyone?
    how to fix it?
    comon problem?

    My L1T has a problem with staying in high intermitently, it is very finicky to get it there and then drops out frequently. The funny thing is, it seems worse with used batteries and less bothersome with brand new.

    Hmm, my L2T seems to be having problems similar to that, although maybe not that bad. First time I noticed the problem it was VERY low like yours, but then after a while of replacing batteries and unscrewing the head/tail it seems to be back to its normal output. However, the high/low flickers a lot and doesn't perform like it used to. Even when it is tightened into the high position it sometimes kicks down into the low, and when trying to go from high to low it turns off then back on.

    i used a pane of glass and some fine wet/dry sandpaper to clean and flatten the body tube so it would make better contact. cleaned the head with deoxit and it's been good to go.

    well, it appears my PCB is scratched up a bit from all the crud in there. (see above)

    (i hadnt opened it untill today, so it came with it from the factory, and it sure diddnt get in through the tail with battery changes being in the cleanliness of my home)

    is a scratched/worn PCB possibly the culprit?
    it sounds like this can paralell the "bad contact" issue...

    i mean i had 6 black/grey q-tips full of what i guess might be aluminum particles.
    its like it skipped the washdown at the factory after it was threaded or something and was shipped right out the door....

    any more thoughts?

    With use the threads will get dark grey very fast! Take a look at it after 30-40 head twist (mode switching). Is the PCB scratched that badly? Can you provide a picture? I had some problems switching to high with mine and 4sevens recommended me to clean everything with isopropyl alcohol. Relube everything and it should be OK.

    ill work on a picture. the traces are scratched around the outside, where it contacts the tube.

    ive allready cleaned and relubed, however because use the light for work, and occasionally at-home, i am probably at more than 40 cycles a week, and i think ive had it about a month now.
    never thought to rebuild or relube or clean something thats been lubed and sealed by the factory. i would have at least figured there was some graphite in there. wolud have figured i could go more than a month without rebuilding it as well...
    allso never thought a light of that price couldnt work as i could even for a month, without chewing itself up.

    granted i am probably harder on my light than most members, but thats the reason i DIDDNT pay $10 for a light...

    kind of a bummer.
    ill get some pics in later today.

    Update: i counted today how many times i switched it to "high"

    6 attempts, but i only got it to fire off twice.
    taking 6 as an average-
    ive got about 180 cycles on it over about a month.
    that actually sounds a bit low.

    even if it were 200, or 250 is that too much to expect from an L2T?
    cant get a good enough picture, but the silver ring on the outside of the PCB is chewed up a little.

    not even sure if that is the problem. is dosnt look that bad. (well, it should look pretty new, but thats not the case.)

    ill try lapping the contact area on the body next.
    I drop in a few times a week. forgive me if im not here when i need to be.

    lapping will help but if the contact ring itself is chewed up it may not make any difference. who did you buy from?

    Stat!





    (meaning this weekend when i have time)
    do i need to strip the conformal coating first?
    and how do i get a soldering iron in there?

    1. lapped the tube all proper like.

    2. beefed up the solder on the PCB.

    absolutely no difference

    i allmost want to say its a short and not an open circut.

    but its gotta be in/on/behind the PCB.

    i even took a bunch of pics to post up in case it worked... but no...

    Mine has been nothing but a pain scince the day I got it. Ive tried everything to fix it and nothing has worked. Now my it just sits in my dresser. I don't think im ever going to but another fenix based on my expirence with this one.

    Several ideas...corrosion where the spring makes contact in the bottom of the cap ( contact not only with the batt, but the bottom of the cap)...also perhaps try streching the spring a tad... and maybe cleaning the threads in the switch area. Sometimes the bottom area of the light gets overlooked when cleaning.

    Mine was the same way. Worked intermittently at best. Cleaned everything twice, lapped the tube, etc. Zip...
    Eventually the light would only function on low mode. I've since removed the components on the board and did some work so it runs direct drive with a protected 14500 lithium. It's plenty bright now and it works everytime I hit the switch.

    If my new L1D starts to develop any issues, it will be no more multi-level lights for me. My plain jane L1P has worked flawlessly since day one.

    well, its clear i need a new head.
    i hope i recall correctly that its $30.

    to invest in a $45 light.

    yeah right.

    I hereby pronounce my L2T dead.
    i am lucky to get "low" out of it.

    it shall sit. and rot. on ye shelf of spare parts.

    Thats a very fine offer, and truly above and beyond any expectations ive had, since i did not purchace it from you or your store, but some random amazon seller.

    however i cant accept it. i want to be able to give the word straight about any product, and treatment like this may be viewed as comprimising- i cant and wont go there.

    have you proven to me that you are an excellent vendor?
    yes. you are easily more than fair and are pretty driven to have happy coustomers. but it seems this problem is not yours to fix?
    i am amazed and thankful to be your coustomer, but a new light could not make me more pleased with your service.

    the last thing i want for either fenix, a fenix rep, or myself is the impression that quality/engineering issues can be "bought off". -none of us would win there, other customers might lose in the long run, and not only might fenix look bad for it, but you and i would too, and- nothing would be solved.

    if fenix has issues they need to look into - well, thats okay.
    by all means lets get the issues out in the open and air them out.
    i mean whats better than a company having the information available it needs to improve and address the problems down the road?

    I would be willing to send the L2T to you if you can have the engineers/designers/factory folks look at it, so whatever problem can be identified and corrected, so your future coustomers might not have these problems- but i cant accept anything in return, you understand.


    i wont be able to send it for a while as i have my hands full for the next few weeks. ill be in touch with you about it when i can.

    thank you. again, you are too kind.

    You make too many assumptions.
    This is in no attempt to "buy off" anything.

    All manufacturers have to deal with varying tolerances and manufacturing
    deviations causing defects and malfunctions. Fenix is not the only one.
    Just do a search on surefire and arc. We all have our share of issues.

    Also, I do not service defective lights. They go straight to Fenix
    engineers for analysis. However, I don't like to keep my customers
    or potential customers waiting. So I send a replacement.
    Is that clear enough for you?

    i bought both my fenix lights from 4 seven. it's good to know he stands behind them. so far my l1p and l2t are working fine.

    Perhaps the problem does lie in the tail as Badbeams3 said. When my L1P arrived many moons ago, it had intermittent problems with switching on and sometimes dimming. A little tightening and cleaning of the switch assembly cured that. Later got an L1T which has seen hundreds if not thousands of mode switches. I'm on my 3rd Fenix now (L1D CE; thanks 4Sevens ) and haven't had any problems yet. Still waiting on my 2AA tube for the L1DCE.

    Is that clear enough for you?

    Thank you for clarifying.

    a good deal of my post was in efforts to dispell any notion of any "buying off" going on, and gave an example of why it would be a bad idea. its clear to me we stand in agreement, and no one could possibly make that assumption from any information in thes thread, as i see it. I wouldnt have it, you wouldnt have it and nobody else would either.

    i understand that you are a sales rep/vendor, and do not service or repair lights. i understand that you are not someone that makes design or engineering choices, and cant be expected to. i understand that at your discresion you can pass coustomer feedback to your company as you see fit. i dont think my expectations have been that much of anything else.

    when i said:
    "...but it seems this problem is not yours to fix?" -this is what i was refering to.
    First off, you had no obligation to offer me anything for my troubles with my L2T, as you werent the original vendor. I bought the light from some seller on amazon, and it would be wrong of me to expect anything from you. you went above and beyond and offered to make the situation right. i appreciate that.

    ...the second part of it, is that while you may or may not pass along coustomer fedback to your company, you dont service, repair or make design or engineering choices, therefore, my issue with the L2T is not something a sales rep/vendor can correct.
    when i said "...but it seems this problem is not yours to fix? " i was allso refering to the fact that i felt it was more of an engineering issue, and less of a sales issue.

    I must say that i did put my L2T through some severe conditions, that are notorious for bringing out weaknesses in any product.
    i went through 2 pairs of angle cutters, 2 pairs of linemans pliers, 2 sets of screwdrivers, 4 razorknifes,and 2 levels in just short of a year untill i found products that would stand up to the job. i can see its a tough task for any manufacturer.

    If my L2T had a slight manufacturing deviation that would normally have gone unnoticed in the hands of anyone else, it was just a matter of the luck of the draw.
    i understand that not every product that comes off any assembly line is going to be a perfect piece. for the price, however it would have been reasonable of me to expect it would be much less likely. that being said, there are a few fenix lights that have failed, under conditions different than mine, and its my hope that the information in this thread leads to future improvements. i thing fenix has a bright future ahead of it, and thats good to see.

    i am actually a bit thrilled that you can confirm that fenix engineers look over the products that come back. im glad you shared this information, as not all companies do these things anymore. its actually a bit exciting, because in some cases, with some products, they just end up in the trash.
    i am still be willing to contribute my L2T at some point so fenix can better their products- if you are still willing to make that happen. I am gearing up for a cross country move, so i cant be sure of when quite yet.


    allso, i have to say i appreciate doing buisness with you.
    My L2D-CE I purchaced from you seems to be holding up much better than my L2T, allthough it has its quirks. regardless, it is serving me well, without any showstoppers so far... I plan on giving my second L2D-CE that is still in new condition, with only a few hours of use, as a gift in the original box with all the trimmings and a proper set of NIMH batteries. I am sure it will be well recieved. if you feel there is any more to discuss, i would wellcome a PM whenever you like.

    its rare to deal with people with this much care and concern, and im glad that if i decide to buy a fenix again i would be in such good hands.
