It only lasted 2 rides.

The included USB cable helps get it in to odd-shaped locations, but then you have to remember to bring the cable with you anywhere you might need to charge.

Also, for weight weenies, it’s super light.

I had slaved over what bike light to buy to keep me visible at night, and I finally settled on this guy. This light has a powerful, wide beam, but what really drew me to it was its simple, slick design. It is also remarkably easy to mount; the silicon strap and magnetic clasp are pretty brilliant. The light has four modes, three of which are designated by blue (maximum output), teal (medium), and green (low). The fourth is the "blinker" mode, which lacks an indicator.

I can't comment on the battery life because I've only taken it on short rides so far, but I will note that the USB charging functionality, while convenient, has me a little skeptical. After a full charge, the battery light on the Blinder will turn green, but if you turn on the light and quickly turn it off and then try charging it again, you'll find that the battery light goes red (indicating that it is charging) again. This would be normal if it weren't for the fact that it takes a long time for the charging light to go green again. For now, I'll assume that it's an indicator issue, as the battery couldn't possibly drain so much from turning the light on for a single second.

This bicycle headlight has gotten a lot of industry buzz before it’s official release last month, and this is one case where the product lives up to the hype. The USB charging system is simple and fast—it’s a proprietary charging cord fully charges my headlight in four hours. The mounting system is simple and more secure than any other headlight I’ve seen, such as the minewt and the knog blinkys. It comes with two strap sizes and a helmet mount. If there’s any movement in the light such as a pothole or sudden bump, the light does turn off automatically. This happened to me on my first real ride using the light, so I changed to the smaller strap. Problem solved. In full disclosure, I actually purchased two of these—one for my helmet and one for my handlebars. The helmet mount is as simple as the handlebar mount, and when I commuted after sunset from Downtown Los Angeles to Pasadena (14 miles) last week, adding a Rose Bowl loop (3.3 miles) in complete darkness, but with both Knog Blinder Arc 5.5’s on medium, I got tons more respect from drivers than I ever have before. It felt like I was the police. This product may be the safest light on the market. Also, for weight weenies, it’s super light.

This light is super super bright, and easy to carry and remove.

Knog customer support is awesome, although I think there might be a lost in translation thing going on. I didn't fully secure the bolt under the strap to the light, needless to say it went flying off of my bike. I lost the bolt. I contacted Knog, a day later they replied and said they would send me a replacement. No questions asked, no receipt needed, they paid for postage. I expected to receive a bolt. a few weeks later, I received a full new mount and some straps, which was great but no little bolt included. I contacted them again, and a few weeks later I finally received the small bolt. Anyway, no fuss, great customer service.

The only complaint I have is the awkward charging of the light. They include a few weird little usb cables, and conversion cables. The cable included is super short and doesn't really work in any of my computer USB situations. I typically charge this with a Jawbone wall charger, but the weight of the light will usually make the light fall out. I need to come up with a better way to keep this constantly charged.

I've reviewed dozens of bike lights, including a handful of other Knog headlights, on my website The Bike Light Database. I've been fairly critical of Knog's products in the past for putting too much emphasis on style and not enough on function. Fortunately, the Arc 5.5 keeps the former while improving the latter.

The optics are great for a light in this price range. The diffusing lens spreads the beam across the whole road, instead of just making a single spot of light. I measured 1:35 of runtime on the highest setting, which is fairly good for a light with this output in this price range. It certainly beats Knog's Blinder Road 3 which only lasted half an hour at 300 lumens.

I'm not a fan of the USB recharger that's built into the light. It's too difficult to plug into a computer or charger directly. The included USB cable helps get it in to odd-shaped locations, but then you have to remember to bring the cable with you anywhere you might need to charge. I accidentally broke the USB plug on the light and had to get it replaced by Knog. Fortunately they replaced it free of charge.

For beamshot pictures of this light and a more in-depth technical review, visit bikelightdatabase.com/knog/blinderarc55.

As with most of the several doze bike lights I've reviewed, this light was received as a free sample unit from the manufacturer. No compensation or editorial input is received from the manufacturer.
