  1. Excellent flashlight !!! Review Rating

    Posted by shek on 10th Oct 2011

    I can imagine the stories that our ancestors would’ve devised, were we able to send a Fenix TK40 back in time to them: They might tell of some mighty hero who journeyed up into the sky and harvested the sun, banishing it into a metal rod:)
    it’s just as bright as a car headlight on turbo (highest) power. I’d keep on going, but I think my TK40 would start blushing!
    Fenix now has a couple of other similar sized lights with more lumens (like the TK45/41/70 etc); but only slightly more so except the tk70which is ways ahead. If I get my hands on any of these other lights, I’ll be sure to review them, but the TK40 is excellent. As I’ve stated, it’s every bit as bright as my car headlights on turbo, and the longer-lasting medium and high settings are still uncannily bright. And for you who aren’t lumen-addicts, the low setting is nice and unobtrusive. this is an older model that has been tried and tested! check out the link below to see a crazy ausie guys torture test of the fenix tk40 and it still worked!
