18650 ultrafire 4 Customers Reviews

  • Good Light - Bad Battery

    posted by peterhop

    Pros:Very bright light, the 4 modes are useful. The design of the case is eye catching. The unit I purchased is mounted on my bike helmet. To achive this I had to mnufacture an adaptor plate to accept the lights existing mounting bracket. Over all a good product, with one exception, covered below.
    Other:Good & useful light, if the battery would last as per claimed specifications.
    Bottomline:Buy but check the battery quality.
  • Lots of "light pr.$"

    posted by Bighope

    A fantastic flashlight for people like me (who love flashlights).. Living in Norway with lots of dark nights/evenings, you need too own some flashlights, but this is now my favorite small size,great light flashlight.
    Bright and nice light, in compact flashlight.
    If you feel the standard 200lm flashlights sold everywhere is a bit weak, and need a handy, small, easy to bring along flashlight; this is the right one. and compared to other 200lmsold in Norway, the price is the same!!!Don't think to much, just buy!
  • Well built bright bike light / headlamp

    posted by Fridfjell

    This is a very strong light.The beam is well spread for running / bicycling.Build quality is good.
    I have not yet tried attaching the lamp on a bicycle, but that should work ok as well I think.
    I recommend this bicycle light/head lamp!
  • Seriously bright, well designed.

    posted by GraemeEvans

    Extremely bright smooth beam, fades from spot into spill without hard edge.Massive lighting rangeBrightness modes start on low and work up (much better than coming on in blindingly bright first!) Most of the time Low will be enough to cycle by.
    Good build quality, nice optics. Definitely around 1000 lumens, not sure about 1600 though... but thats compared to my other professional properly rated flashlights - Chinese lumens are apparently different. Its definitely as much light as you could want, think car headlight.
    Serious lighting power. Very compact. Nice beam pattern. Really pleased. The low-high instead of the regular high-low mode arrangement is refreshing. Additionally off is push and hold, so no need to cycle modes to find off, or off whilst changing brightness.
  • Excellent Bicycle Lamp!!!

    posted by renatoluizlopes

    Excellent Bicycle Lamp!!! It really solved my problem in my nightly rides. I had bought one before, but too bad, it couldn't illuminate enough... but this one is waaaaayy better... it explain itself why one cost U$5.00ish and this one cost U$37... it worth it, no doubt. It capable to illuminate well a great area, good material, easy to use, and runtime over 3 hours using High light mode... perfect for me.
    I made an adaptation to use it in the helmet. But very good to use it on the handlebar as well.
    I recommend it.
