    Sooo, my E01 died last week :( I havw had it for a little more than a year and it have been a companion almost everywere.
    So the tricky question is, should i look for a new E01 or for a new manuifacturer?

    I have lookt att
    • FourSevens Preon P1
    1,8 lumen - 23 Hours.
    AAA battery.
    Expensive in my eyes.
    Feels like it´s complicated to use
    • Olight i1
    4 lumen - 72 hours
    CR 123A battery = expensive
    Maybe complicated
    • Sunwayman R01A
    10 lumen - 21 hours
    AAA battery
    Easy youse
    cheap

    And som thoughts on that please :)

    Are you sure that it's dead, have you tried cleaning the contacts etc?

    Oh, if your meter runs off a 9V battery and you put it on that mode, aren't you putting 9V through the LED? Maybe that's fried it anyway??

    I would say get a new E01. It's a great little keychain light, really hard to beat, at least at that price point.

    In my experience, they are pretty rugged. I am truly sorry that yours gave up on you.

    thol Could you post a picture of your E01? I'm curious to see how the black anodizing has held up.

    The usual points of failure: clean the contacts on the back of the head with an eraser or a q-tip and alcohol.

    Check the tube itself around the spring at the bottom of the body. A tiny piece of aluminum packed between the spring and the tube wall can test the connection and flow of electricity.

    The base of the tube is a spring soldered to the tube wall.

    When the battery's negative end makes contact with the spring, the electrical current flows from battery to spring to wall.

    If something is impeding the flow from spring to wall, you can make another bridge by inserting a piece of aluminum foil into the tube and packing it in around the spring so it makes another point of contact between the spring and the wall.

    Mind you, this is all assuming the head still works - I usually test that with a battery and a paperclip to make the connection.

    Yeah what ^^ he said... seems that over half the twisty/mechanical clicky problems I read about (and I enjoy following failure threads) are due to minor corrosion build-up somewhere through the negative electrical path: spring > clicky (if present) > tube wall > head and is easily solve with some simple disassembly, cleaning, and lubing.

    People often say they prefer twisties to clickies for reliability, but I always EDC a piece of tinfoil in my wallet, for one, to field bypass a mechanical clicky failure in a similar way as tmedina mentions (ie, I can turn my clicky into a twisty), but more importantly for me, to rig my 1xAA light to run anything from a 9V to 18650 in a pinch.

    Note, however, that the tinfoil ball trick may not work if your inner tube walls are anodized.

    Another E01 would be a good replacement. Consider the E05, three modes and very simple UI.

    • Three Output Modes:
    • High: 85 Lumens (Ni-MH: 1 hour; Alkaline: 45 min.)
    • Mid: 25 Lumens (Ni-MH: 4 hours 15 min.; Alkaline: 4 hours 15 min.)
    • Low: 8 Lumens (Ni-MH: 14 hours 30 min.; Alkaline: 15 hours)
    • Waterproof to IPX-8 standard. 30 minutes under water to 6.5 feet/2 meters
    Battery one AAA.

    Available in black or stainless steel.

    Did a battery leak in the flashlight? It's unusual for a spring to just get dirty, a least in my experience.

    You can try using a q-tip and rubbing alcohol to swab the areas around the spring, as well as the spring itself.

    I've had one E01 "fail" the same way - I ended up just leaving the foil at the bottom as an extra connection.

    I'd use some forceps, needle-nose pliers, or just a bent wire hook to fish the spring out, clean it up with some water & baking soda (which would neutralize acid), and reinstall it.
