I am the type of person who reads the reviews before buying something. I read many reviews on several bike lights. I knew what I wanted to spend and started reading about the lights in my price range. Many of the reviews of this light complained about the way it attaches to the handle bars. I found that this was not a problem. This may be because my Cannondale has thicker handle bars than some of the bikes in the reviews. I am not sure, but it fit easily and securely. The other complaint was about the strength of the light. Most reviews claimed that you would not be able to see very well on a dark trail, but that it was sufficient in a lit city. This is not really the case. I bought two and mounted them easily on my bike. I ride on dark trails at night and have found that even when riding fast I can see really well. This is true even with only one turned on, though I prefer both on at the same time. They don't light the trail like my Honda CRV, but it is plenty bright. Once while riding through the city I had the lights on strobe so that cars will notice my presence better. They are pretty bright and really show up in the reflective surface of street and stop signs. Two motorcyclists riding in front of me saw this strobe effect and pulled over, only to realize that I wasn't a cop. They were probably drunk, but that is still pretty bright. I am glad I chose this light. The battery life is also great, especially with rechargeable batteries. As for the people out there bashing this light, yeah it probably isn't as powerful as one of those $300, $400, or $500 bike lights. However, this light was $32 and more than does the job. If you are looking for car or truck headlight performance, you are not going to get that with a $32 1 watt LED. If you want a very good and reliable bike light for riding at night in and out of the city, this light is gives great bang for the buck! Hope this helps! 5 stars

Pretty good Headlight, beam seems strong enough for slow riding thru the city. If used with a flasher Headlight it'll work more than adequate for paced commutes. The construction is a sturdy plastic.

The Headlight uses a cheap mounting bracket that isn't great. It doesn't fit very well on the handlebars so you'll end up using a cut up old tube or tape to help keep it snug. You should still be able to tilt it back and forth for use in high/low beam (level it down towards the street in front of you) and flash mode (level it up towards traffic). The "close" pin doesn't snap back to keep it in "closed" for some reason but my Headlight didn't fall off yet.

#1 beam seems to be "low" for some reason instead of high on my Headlight. #2 high beam is brighter. #3 beam is flash mode.

The Headlight is not heavy, very decent size, compact, detaches easily from quick release mounting bracket. The button on the Headlight is rubber so it doesn't respond very well when you need to change modes quickly while riding. If you are in bright city lights, it's impossible to tell what mode it is in because the beam is barely visible on the ground and there is no extended visible light (or clear lens area) to see the light/mode while you are riding. The side of the Headlight has two clear lens/indents that aren't very visible from the side. The Headlight uses 2 AA batteries (use rechargeable batteries) as there is a low run time on alkaline cell batteries (5-18 hours).

If you are in city lights, the beam is barely visible on the ground, it's best to use the flash mode but level it up towards traffic or it won't be visible. The flashing lights in flash mode in darkness are visible on stop signs for at least 8 or more long city blocks, it's very good. The "flashing" mode bright flashes, are not very disturbing since it's impossible to see the flashes because there is no extended visible light (or clear lens area) to see the flashes while you are riding.

The front end lens area of the Headlight is very small (1 inch across - light mainly visible from front) but 60 feet away, it (on high beam) appears as a larger bright dot to far away traffic. It's best to use the Headlight for seeing the street in front of you with Another flasher "to be seen" Headlight, or as a flashing light in flash mode with Another flasher Headlight, double the flashing "to be seen" lights. If using Headlight on high beam, you can even level it up towards traffic, it is very bright.

The spread of the beam (high/low) is very adequate to see in front of you riding in darkness.

When using the high/low beam it's best to level it down towards the street in front of you, the beam is very adequate for (8-15 mph, slow city riding) (5-12 mph slow trail riding in darkness). It's best to use the Headlight with a flasher "to be seen" Headlight (Blackburn Quadrant Light is very good) in traffic.

In all, some technical/practical issues with the Headlight design, but a very, very good high/low beam for slow riding thru the city.

PROS: Headlight is not heavy, very decent size, compact, uses 2 AA batteries (lighter), the beam is strong enough for slow riding thru the dark city or slow trail riding in darkness, Headlight detaches easily from mounting bracket, flashing lights in flash mode very good, spread of the beam (high/low) visible in front in darkness is very adequate, The "flashing" mode bright flashes are not very disturbing/visible to rider, If using Headlight on high beam, you can even level it up towards traffic for a very bright "to be seen" light, lower price.

CONS: cheap mounting bracket that isn't great, light not very visible from the side, button on the Headlight is rubber that doesn't respond very well when you need to change modes quickly while riding in traffic, impossible to tell what mode it is in (in bright city lights) because there is no extended visible light (or clear lens area) to see the light/mode while you are riding, low run time on alkaline cell batteries.

With this Headlight, riding my bike at night, it allows me to see reasonably well. This is a very nice "to be seen" or "to see" light. Highly recommended for those on a budget and commuting or non-commuting bike riders.

This Headlight is barely visible in the rain. If you commute in the rain or ride fast, invest in something more powerful.

Planet Bike Blinky Super Flash Tail Light 4 stars

This is a good option for road riding, and commuting on lit streets. I use it for a 45 min workout at dusk. The super flash mode is awesome. Pros - high powered spot, only takes 2 AA batteries (easy to carry spares with you) SUPERFLASH MODE. Cons - mounting is questionable (not for off road use) would be nice to have a wide angle option (sliding or swinging diffuser) works well on headlamps. all in all definitely a good buy. 4 stars

I have both the one-watt Blaze and the 5-LED Beamer lights on my bike (note that I am comparing the one-watt Blaze, not the half-watt Blaze). I use the Blaze for constant-on illumination (to see) and the Beamer as a blinker (to be seen).

First of all, there is NOTHING WRONG WITH THE MOUNT (which is the same for both lights). Please ignore other reviews to the contrary, which were posted by people who are apparently unable to read an instruction sheet.

The mounting strap is ADJUSTABLE. It will accommodate very small handlebars, as well as massively oversized handlebars. If you turn the mounting bracket over and examine the underside, you will see that the mounting strap has ratchet-teeth. There is a keep directly beneath the mount which holds the strap to the desired length. If the mount is too loose, push the strap towards the mount to ratchet it to a smaller size. If the mount is too tight, use a small screwdriver to hold the keep up as you let the strap out. The mount may be further adjusted by turning the set-screw (by turning the cam-lever). Don't make it too tight, or it will be hard to adjust vertically.

The mount is very secure, yet the lights are easily removed (and can easily double as a flashlight when needed - and you could easily hold it in your teeth for roadside repairs).

Photos of both the Blaze and the Beamer look rather similar - I wondered if they used the same plastic housing. But the Blaze is substantially larger than the Beamer (in both length and diameter, even thought they both use the same size (AA) batteries). As I said before, the mount is the same.

In blinking mode, the Beamer is actually brighter (overall) than the Blaze. This is because the Blaze (wisely) does not flash at full-intensity all of the time (otherwise you would absolutely blind passing motorists). The Blaze mostly flashes at low-intensity, but every sixth or seventh flash is at high-intensity. The Beamer flashes at maximum intensity with each flash, which is brighter than the Blaze for most flashes, but not as bright as the occasional max-flash of the Blaze. Overall, the Beamer is brighter in flash-mode, although I am not sure it is better. But it is sufficient for my needs.

Many bike lights are designed like flashlights, where the beam is really visible only from the front - someone viewing from the side would not see any light from the bulb itself (only the things that the bulb illuminated). Both the Blaze and the Beamer have lens bezels which fully expose the bulb to aspect view, giving these lights about 210-degrees of visibility.

In steady-on mode, there is really no comparison in lighting intensity. The Blaze has a high and low mode for steady-on, while the Beamer has only one steady-on mode. My comparison is only using the Blaze in high-mode. The Blaze's intensity is why I give it five stars (I gave the Beamer only four stars because it was lacking in comparison).

The Beamer's steady-on mode is rather hazy and unfocused. The five-bulb light source can be seen in the uneven lighting it produces. The Blaze (which has a single bulb) produces a much whiter and brighter light which is highly uniform. I'm not sure I would recommend the Blaze for absolute pitch-dark riding over difficult surfaces (such as singletrack wilderness and mountain trails), but it is perfectly sufficient for fill-lighting in urban commutes, with occasional very-dark spots. The Beamer is sufficient only for urban fill-lighting - I would not want to use this light in very dark conditions.

If I found myself riding an extended bit of pitch-dark road, I would reconfigure my lights to use the Blaze as a distance light and the Beamer as a close-in light.

Some posters complain that NiMh rechargeable batteries are inferior to alkaline. I am not able to discern any difference in the Blaze. NiMh batteries are 1.2 volts, whereas ordinary batteries are 1.5 volts. However, it is not really voltage, but milliamp-hours (mAh) which determine a battery's power potential.

The Energizer e2 MiMh batteries can be charged to 2,450 mAh (milliamp-hours), while fresh Energizer Alkaline batteries are rated at 2,850 mAh.. So the difference in power is about 8.75%. I cannot perceive this difference. However, a freshly-charged MiMh battery will ALWAYS out-shine a somewhat-discharged (but still relatively new) alkaline battery. There is a temptation to use disposable alkaline batteries until they are absolutely worthless - thereby depriving ourselves of good lighting (few people toss out batteries because they are only at 91% power - the point at which fresh NiMh batteries exceed their 8.75% discharged alkaline counterparts). It is better, IMO, to have a slightly inferior battery that I can recharge each evening, so I always have an absolutely fresh battery, rather than a disposable battery that may be slightly brighter for the first hour or two, but soon looses ground to a freshly charged NiMh battery.
5 stars

This is a great light for the price but possibly more suited to the recreational rider such as myself.
It has three modes low high and flash although the difference between the low and high settings is not great.
You will need a rubber strip inside the bracket to prevent it from moving this is not supplied at least there was none with mine.
I found the fitting of the bracket somewhat difficult it consists of a ribbed strap which is pulled through a slot and locks into place but it would not lock on the last two ridges, I assume that was because my handlebars are a small diameter but, with the use of a rubber strip providing an increase in diameter and a good grip it was much easier, it can also be tilted without becoming loose.
The light is quick and easy to remove for security.
The bracket can only be fitted facing in one direction as the light only slides on in one direction, that seems an obvious comment but it is easy to get wrong when you're fitting the bracket without the light attached.
It was delivered on time and well packaged.
I considered 4 stars because of the bracket fitting problems but those may be specific to my bike and were solved with the rubber strip plus fitting the bracket is probably a one off for most people.
