I was was checking out this bike light. It looks good enough for me. I (rarely) get lost on trails around dusk, but more importantly I commute - a lot by bike. I really just want to be seen.

What caught my eye was the review: there are nearly 500 5 star, and a mere 17 1 star review. I'll take my chances. But this is where it starts getting questionable.

First off, they make sure you get to read #1 Bike light on Amazon, if it is. Okay. But, in the video they use to advertise it, they claim that most bicycle accidents happen at night - they don't, as you can read about here. They also flash statistics in the video that aren't related to the time of day... at all....

That said, this government source says it is more risky to ride at night (more people probably ride during the day. Is it proportionately more dangerous?)

Is this marketing practice unethical? I don't want to reward unethical advertising with cash, but in the grand scheme of things it's probably more important that the are selling a quality product if they say they are.

Could the ratings have been (partly) faked?

Has anyone used one? I can't seem to find a review of the dang thing on youtube, as popular as they are supposed to be!

    With cheap bikes lights usually failure rates are what bites you. Many cheap-crap sites have huge issues with stuff that works amazingly well, sometimes for weeks, before it fails permanently. For sellers of that stuff gaming review systems is part of their business model.

    In general, we don't go for shopping questions, but this one has enough non-shopping things so I won't vote to close. On the Bicycles.SE blog, we do have a set of reviews for some decent lights: bicycles.blogoverflow.com/2013/09/the-2013-headlights-review

    I had a similar looking light I got cheap from amazon. Do yourself a favor and don't get cheap lights. A cygolite metro light will do a great job for about $60.

    Do yourself and your local bike shop a favor. Check out what they have and what they recommend. It will certainly cost more up front, but will save you money in the long run. And while you're there get a second tail light.

OK so I do a lot of bike light reviews. I originally started writing them for this very site's community blog, and now I run a separate website called The Bike Light Database.

Has anyone used one? I can't seem to find a review of the dang thing on youtube, as popular as they are supposed to be!

I've reviewed this light specifically, and can say that while it is cheap, it's not a good choice for someone who seriously bikes at night. The build quality is poor, it doesn't put out much light, and the optics are crap. There's no side visibility. The mount is annoying to use and bulky. The light dims quickly as the non-rechargeable batteries drain, and the contacts are of poor quality so sometimes the light just stops working unexpectedly.

Is this marketing practice unethical? I don't want to reward unethical advertising with cash, but in the grand scheme of things it's probably more important that the are selling a quality product if they say they are.

I think their page makes a lot of dubious claims. The taillight in the video isn't the taillight they include. My rule of thumb is, if the Amazon product title says anything more than the name of the product or is more than 1 line long, I don't buy it. They're trying too hard to sell it and it's probably crap.

Furthermore, some of those pictures are very obviously other products. This is a real beamshot of the light that I took. You can see an interactive version to compare it with other lights on the site.

Could the ratings have been (partly) faked?

Looking through the reviews on the page you linked, many of them are verified purchases, but not all are. I think it's unlikely that most would be faked, but there may well be some fakes. The real issue is that to a lot of people, it seems like a perfectly good bike light because they've never seen a good bike light. It's cheap, it does what they expect (lights up), and it doesn't have any immediately obvious problems, so it gets 5 stars.

For people with a small budget and simple needs, this light is just what they want. That doesn't mean the advertising is truthful, and it doesn't mean the light is any good. It's the same as asking somebody who bought their bike at WalMart if they like it. "Oh yeah, 5 stars, it's great! Totally has pedals, moves forwards, even stops when I use the brakes!" And yet we know better here than to buy a bike at WalMart.

I've also addressed the issue of "eBay China lights" in my FAQ. While on the surface the specifications look just as good as any other light, it's the details of the design (not to mention the ethics of the company and their marketing) that make the difference. There's also a lot of lies in the specs that companies list - I highly doubt this light actually puts out 200 lumens, for example.

Hopefully that sort of answers your questions. If you'd like to talk more about lights, ping me in the site chat or leave a comment, I like discussing lights! And if you're looking for a better light to choose, I have some pretty detailed suggestions on my lights site!


Sellers on Amazon.com have a lot of leeway in the naming of their products and advertising script they use. In that sense, Amazon is becoming more and more like ebay.

Rather than the feedback (or lack thereof), the technical specs of the light should be warning you to stay away. Powered by only 3xAAAs, there's no way this light is getting more than a few dozen lumens. The AAAs don't have enough amperage and the fact that the light is using 3 of them indicates that it's more or less direct-drive and isn't using any sophisticated buck-boost circuitry.

Even the advertising photograph showing it lighting up a trail is fishy. The light on that bike is clearly not the light advertised. It's much larger.

If you really want to light up the night, you have to get a light that's powered by something more powerful than alkaline batteries. Most of us with 300+ lumen spots use lights powered by three or four 18650 rechargeable lithium-ions. These can give off a constant 3-4 amps of power each.

And yes, reviews are easily faked.


The linked flashlight is absolute crap: i have bought one for about 2 $ off ebay, inclunding a cheap tail light, and it is bright enough to lighten up the way to the bathroom at night without disturbing my wife. Not more, not less. For serious commuting, i would recommend a USB-chargeable bike light, like the Lezyne Power Drive or Super Drive series: http://www.amazon.com/Lezyne-Power-Drive-LED-Silver/dp/B008R5Q9OG/ref=sr_1_8?s=sporting-goods&ie=UTF8&qid=1403247933&sr=1-8&keywords=lezyne+led

I have a similar one from BBB (USB, Li-Ion, symmetric emmission) with measured 450 Lumens, and use it at about 150 Lumens most of the time. I also built a small lid to avoid blinding forthcoming riders, and as a side effect, the lid reflects more light to the ground, making it more efficient.

  • on the plus side, at least the light was good for something ;-)

In the probability I'll get dinged I'll put my two cents in. I commute and night ride on the road a great deal. I have used niterider and lezyne lights to good effect, but they were not cheap. A friend bought a light off of ebay, and at first I scoffed. Not promoting it, but the name is "Bright Eyes". It is insanely brightly, has a strobe mode that startles drivers during the day and costs 45 bucks. He has had his for over a year, and I bought the second version 9 months ago as I like to ride long and do not find the 2 hour lifespan of the lezyne or niterider system adequate.


  • It is very, very bright. I use it for commuting and drivers will wait for me to pass when they use to just dart out in front of me.
  • The strobe setting makes you nearly impossible not to see during the day. I feel bad using it and often tilt the light down 45 degrees.
  • I have yet to date run the battery down on 4 hour rides.
  • 45 dollars? That's a pro!


  • The beam is narrow and not nearly as useful as the lezne and niterider systems I (use to ) ride with.
  • Battery is external, which may be a negative to most but I personally like
  • No warning light to let you know when you are going to run out of juice. That said, its never been a problem.
  • leaving battery plugged into light will drain the battery over a week. Zener diode anyone?

In this case with this light I have been very surprised and very happy with the product. It is a little unpolished when it comes to features and the lack of a wider lateral coverage area for the beam is a negative but not a serious one.

Regarding your light, I do think caution is in order. You generally get what you pay for. But there are exceptions. Take your time. The great thing about amazon is that if the product sucks, you can return it with no issues.

Good luck! And remember, people use to crush the Japanese for low quality work. Their economy transitioned out of the bin and is now a by word for quality. China is in that transition itself.
