Thread: ML50LX

    Default ML50LX

    Hi all,

    Total n00b here, searched for the Mag-Lite ML50LX and didn't find a thread in relation to the issue I've experienced, so I'm throwing up a new post.

    I bought the ML50LX LED 2 Cell C in March 2017 and have used it lightly as my "upstairs" light (got sick of a weak Rayovac dimming out on me whilst under the sink and such). As I've had great luck with Mags of various varieties throughout my life I figured I'd make the investment in something I'd hopefully have forever. Definitely love the compact design and substantial brightness - I'm not an aficionado so I'm not really hard to please either though

    Long story short, the light was working fine until I opened the chamber to check the batteries. When I put them back in, the light no longer powers on. Tried new batteries with no effect. Checked to ensure that the tail cap was fully tightened and that the metal coil is seated, and still nothing. Disassembled and did a visual inspection yet couldn't identify anything glaring.

    The only thing that happened that I am aware of is that when I was asleep on the couch my wife knocked it off of our adjacent couch onto our hardwood floor, a drop of little more than a foot I'd say. However, the light was used after this and still worked fine, it was only when the batteries were removed and reinstalled that it failed to power on again.

    Anywho, I surmise that the issue is LED burnout, LED module failure, or else the switch is broken, though I can't believe this would be the case when it's been used so lightly and suffered very little trauma. Coincidentally, anything involving the LED wouldn't be covered by warranty.

    So I shot them an email and they're asking for me to send it in. I think I'm going to do it to see what they say, but
    I was wondering if anyone had a similar experience and/or any recommendations to repair it without going through that nonsense.

    Thanks & Regards,

    Speedle

    I could be 100% incorrect here but if what is you are describing is correct it sounds like you have either a loose and or bad switch. Tighten the head down all the way and shake it closely to your ear. If you hear a rattling noise that sounds "lighter" than the big batteries bouncing around it is a loose switch. I have yet to do anything more to my several LX XML2 Mags but install custom ground optical quality lenses in them. Thus I am not 100% sure how one would tighten the switch.

    Not trying to be sarcastic but did you put the batteries in with the positive end toward the head of the light?

    WDR65 I see you are newer member yes? Question's regarding lights and their correct usage are more than welcome at any time here. Yes...pay close enough attention and you will see these basic questions and inquiries come up on a semi regular basis. I cannot help but be taken back a bit by how many people have come through the big light forums utterly clueless on how to use a light period let alone a modern day multi feature high output LED light running off of batteries of potentially very dangerous chemistries. This is also the very FIRST report I have read here or over on BLF and the great Germany based Taschenlampen.com of anybody actually having a basic functional issue with ANY of the new gen XML2 C and D Mags. I am sure there are indeed more issues out there it is just I am confident most non flashaholics would just not know what to do with it if something went wrong and just stick it in some corner somewhere it IS a Mag after all.

    Was going to ask that too.... done it dozens of times.

    Another idea is to unscew the tailcap a wee bit at a time and see if it lights. I have a mini mag that won't turn on until I loosen the tailcap slightly. It turns on and once on I can tighten the tailcap. If it doesn't get used for 2 or 3 days it does it again.

    CelticCross74,
    Not new, I've been on here for over 12 years. I read a lot but don't post much. I just thought without a preface it would be semi insulting to ask someone a question that seems simple. I've put some in backwards myself.

    right on man. The OP's issue actually is the first time I have read of such a thing with the new gen XML2 Mags. Just a matter of time before the new Gen bodies start showing up as hosts for sale all over the place...Hmmm...

    Gave this a shot, I can't seem to hear anything out of the ordinary.

    No offense taken, believe me I've had plenty of these moments hahah. But in this case batteries are installed correctly.

    I am very surprised to be having such a seemingly random, rudimentary issue - one minute it was fine, and the next it was nonfunctional. I went for this light believing I'd have it for a very long time - I've had great luck with Mags for years.

    Tried this as well, unfortunately no dice. It's driving me pazzo!

    So, ML customer service got back to me. They've asked me to send it in for warranty repair. I think I'll give it a go unless I can come up with a better plan. If they won't repair it I might need some recommendations to mad-scientist it into something cool.

    hmm interesting. You should be fine with ML's customer service just have to wait the turn around time. Gotta add here I just got the 6 D cell XML2 Ml300L and this thing is AWESOME!! SEVENTY ONE HOUR RUN TIME AT 700+ lumens WHAT??? YUP!! I know I know "Ansi down to 10% etc" but this is still the most output for this long at all the lights different power levels for THIS long "ANSI numbers of course" LED light that I am aware of....I put a glass borofloat lens in it it is STELLAR! Max output in my copy looks WAAAAY over 700 lumens I really wish I had a light meter....Keep us posted OP

    Update to anyone interested:

    Procrastinated/was busy for a while and waited to send out the light until right before the holidays. Just got my ML50LX back yesterday from customer service and happy to say that it's working with no issues.

    Comments from tech: "JL (TL) Light failed electrical test. Light was disassembled and inspected. Replaced switch, cleaned off all contacts and lubricated threads. Light passed all tests and functions per design."

    So, looks like a faulty switch was the culprit - hopefully it's not a widespread issue for other users. At least all I had to pay was shipping. Glad to have a functioning light back
