Master 860 Lumen USB Bike Light/Tactical Flashlight

I've had this bicycle headlight for about a year. I am a year-round bike commuter in Portland, OR. The first thing I can say about this headlight is that it is a genuinely solid piece of equipment. I've taken this light camping, hiking, used it while working on the underside of my car, and anything else I'd need a flashlight for. It takes extreme heat, extreme cold, and driving rain with an equal amount of fortitude. I'd hammer nails in to a wall with this if I had to, in a pinch. Its brightest setting is truly, blindingly bright and the pulsing lowest setting is still bright enough to illuminate street signs a hundred feet away. I'm not worried about front-side visibility with this light; although maybe you will be if you're the kind of person who feels the need to ride around the city with a fast-pulsing nighttime trail riding headlight on your bike. It's physically held up fine for the past year and the battery still holds a champion of a charge.There are a few negatives about this headlight I'd like to point out, though. First off, the holder it comes with is fine at holding it steady on the handlebars, but it has an exposed screw in the rubberized part that has, over time, scratched a solid line on the underside of the headlight. It's purely a cosmetic thing, but if that exposed screw wasn't there this light would still be physically flawless after twelve months.More crucially, and this might just be an individual defect with my light, is that if I hit a bump in just the right way, the light will totally turn off. I don't know if it jostles the battery or what, but probably once every 2 or 3 rides with this light I'll have to turn it back on after a rough segment in the road.I'd also like for this light to have a low battery warning. As it is, the light just starts shutting off at smaller and smaller intervals as the battery drains, and that has to be your clue that the battery needs to be charged. If you plug it in every night you won't have to worry about this, but I don't, and sometimes I'll be blindsided by a dead battery because of it.Overall I like this light a lot, but I'd preferably get it when it's on sale. If you're looking for a solid rechargeable flashlight to keep around, this is great, and the hit-a-bump thing may be an individual thing with my particular unit. I'd give it a solid 3.5/5, rounded up to a 4.

First, the basics: this flashlight comes with a USB charging cord (so you can charge the battery in the flashlight; which is nice, since I don't want to have to remove the battery and put it in a charger every time I need to), a lanyard, a bag for carrying the flashlight, An instruction booklet, and a battery. Now, for my personal thoughts: I can't BELIEVE this light! It is SO useful in SO many regards! I had a flashlight that I would often use, so I carried it around on my belt. This light is smaller (My previous light was just a little over 6"(152.4mm) whereas this one is an inch shorter; 5"(127mm). Also, the head does'nt have as large of a diameter, and it's 5 TIMES (maybe more) as bright! Also, just an inch shorter may not sound like much, but the fact that I don't have to worry about bumping this light against NEARLY as many things as I had to concern myself with when I was using the other light, is a GREAT relief to me! Also, when I DO bump it against anything (as is certain to happen) it's a LOT tougher than my other light! Another thing, I like the fact that I can carry it around on me for when I may need it, then just pull it out of the holder I use everyday, (I don't use the holder that came with it, but I may, as of yet) and place it into the holder on my bicycle when I go for a ride, AND the fact that it beats the tar out of my other light as far as brightness goes; and I can use it on the trail, street, or whatever I'm riding on that night, makes it THAT much more useful! The other thing I like about it so much, is the strobe mode (hold the button down from any 'on' mode for 3 seconds) since it resembles a dance-club strobe light, but then has a quick 3 flash succession, then dance-club strobe again, and keeps up this cycle until you turn it off. At any rate, it's a VERY noticeable strobe effect, and WILL get you seen if you're riding a bike, I tried it the other night on MY bicycle, and had drivers yelling (and many other things I won't mention here) so I KNEW they saw me, and you WANT to be seen on the road! It seems you have to be EXTREMELY obnoxious to get a driver's attention these days, but (As I've heard said) "If that's what it takes, that's what I'll do"! Another thing that I'm not used to, (but like all the same) is the fact that you can carry a fresh battery with you, and if your ride goes longer than you expect, (which I've had happen a few times) you can just change the battery, and the light is bright enough to be used alone as well! Nice! The last thing I wish to address is the placement of the switch. It's not as simple as most other flashlights where it's located on the tailcap; and when you're in pulling it out in the dark, it's a little tougher to find the 'on' button, but once you do, you're rewarded with a FLOOD of light! Speaking of which, the light beam seems to be the perfect mix of flood, AND spot! I SO badly wish I could give this flashlight MORE than 5 stars!
