Review: Light and motion vis 360 °

The past few weeks have been absolutely crazy for me. Lots of really early-morning commutes, some late days at the office.


Combined with the shorter days, I’ve had some of the best testing conditions imaginable for a helmet-mounted lighting system that was purpose-built for bike commuters!


Let’s take a look at the gear. The rear part houses the battery, two amber side-facing LEDs, three bright red rear LEDs with a combined output that matches some of the most popular rear blinkies on the market, and a generous-sized swath of engineering-grade prismatic reflective material, all inside a water-resistant case. A rubber flap covers the Micro-USB charging port.


There’s also a small window on the under-side of the unit that displays a multi-color LED which functions as a battery gauge and charging indicator. I was able to fully charge the Vis 360º in about 5 hours, meaning that a full recharge at home or in the office is easily achievable.


The rear part of the Vis 360º snaps onto a plastic base that attaches to the helmet with velcro. I found that getting this part mounted securely was somewhat difficult on all of my helmets. This was the most frustrating part of getting the Vis 360º installed. I eventually found a position that worked well enough with a little bit of tinkering. The headlight snaps into a plastic base that attaches to the helmet with a notched rubber strap. This part was easy to mount on several different helmets. The ability to remove the lighting hardware from the helmet while leaving the mounting hardware attached is a nice touch.


The headlight itself features one bright white LED and two amber pieces to scatter light to the side with a rubber-covered power button on the top, all packed into a small, light and attractive metal shell. The light has three modes: Full power, half power and flashing. The front LED flashes quite rapidly. The rear LEDs always flash twice per second (250ms on, 250ms off) regardless which mode the front light is in. You must hold the power switch for two seconds to shut the unit off.


The whole package looks a bit bulky on the helmet, but it’s surprisingly light at 130 grams. I notice the extra weight on my helmet, but it’s not unwieldy or uncomfortable.


The proving grounds:
A very dark section of walking trail around the community pond where I live. All photos were taken using the exact same exposure settings on my digital camera.


The competition:
Bell Orion. This 3 LED helmet-mounted lamp is powered by two CR2032 batteries. It’s on par with any cheap department store bicycle headlight I’ve ever seen. When blinking, it might draw some attention to you, but it won’t help you see much on a dark road even at a very low speed. What this light (seriously) lacks in output, it gains in run-time. It will go dozens of hours on a pair of CR2032 batteries. Good thing, too, because CR2032s aren’t rechargeable, and they’re not usually cost-effective to replace. MSRP: About $15


Blackburn Flea. This rechargeable light is a decent headlight to use if you want to be seen on a budget. If you keep it slow, the high output setting (used in this photo) is bright enough to alert you to potholes or obvious road hazards in a pinch and run for about 3 hours. Really, though, they’re best suited for riders who ride near dusk or dawn, or spend time riding under streetlights. MSRP: About $25


NiteRider Evolution Halogen (Upgraded to 15W). This was my first serious commuting light, and it features a bulky NiMH battery pack that can be strapped to the bike’s frame. The OEM bulb was 10 Watts, and when it burned out, my LBS only had the 5W and 15W bulbs in stock. With the 15W bulb shown here, this system runs for about an hour. As you can see, it provides a very high intensity spot without much side visibility. This model isn’t made anymore, but you can expect to pay between $100 and $200 for a quality halogen system.


Vis 360º lights up the path more evenly and plenty bright. I have to admit, when I saw 115 lumens listed for the specification, I was concerned that this might not light the way far ahead enough for some of the faster sections of my commute. I usually average about 15 MPH, and never had any problems seeing the road surface far enough ahead for my own comfort. On the high setting, I was getting a little more than 2 hours of total use before the low battery indicator kicked in, but it was still on regulated battery power, with no obvious fade in brightness. Advertised run time on high is 2:30. MSRP: $169


On normal mornings when I leave as the sun is peeking over the horizon, I used the Vis 360º in flashing mode. A whole week of commuting (about 6 hours on the road) without a recharge didn’t even put a dent in the battery with flashing mode. It still registered as “fully charged” this evening when I got home.


Is this unit worth the price? I’d say it is. The system is competently designed and can fulfill all the basic lighting needs of a bicycle commuter with the additional bonus that you don’t need to leave any hardware on your bike while it sits vulnerable and unattended throughout the work day. It has ample run-time for even the most die-hard long-distance commuters and shines far enough ahead that most average cyclists shouldn’t need to seek supplemental light.


I’m giving this one two thumbs up.
