bright! I wanted something small to put in my jacket pocket because I walk home after dark most days, and stick on my nightstand when I go to bed. This is small enough to fit the bill and bright enough to temporarily blind someone if shined in the eyes. perfect.

The other settings are mostly irrelevant to me. The focus adjustment is nice though i'll probably never change it.

I'd definitely recommend this to a friend. Its cheap enough I may buy separate ones for carry and home.

This little thing will blind anyone if you look at them while you're wearing it (which is a good thing, in this case)! It's super handy to be able to be hands-free (pun definitely intended), and it works like a charm. It's comfy, so you forget you've got it on, and it's very powerful, so you don't need any supplemental light. They make great gifts for folks who like to putz around the house or do any kind of work in the attic, crawl space, basement, etc. Definitely highly recommended!

This is a great back light for your bike.  It is very compact, about 1.5" in diameter and about 1" thick.  The mounting strap seems to be made of rubber so it's very flexible.  I have a standard men's 26 inch hybrid bike and it just take one second to mount/dismount this light onto the bike.

As for the lighting, the product description says it has five modes.  However I was only able to count four: bright solid, dim solid, flashing or blinking (I can't tell which), and SOS.  Even in the dim solid state I felt it was still pretty bright.  I am attaching a picture of my bike inside my completely closed garage and the only source of brightness is this light.  The picture is kinda blurry but it should give you a sense of how bright it is.

Overall I am very happy with this back light.  It's bright, many lighting modes to choose from, and super easy to mount/dismount when you need to charge it.

*** I purchased this bike light at a discounted price in exchange for my honest review.

I bought this to replace another Blackburn bike light that I lost. The previous light was amazing, lasted a year or so on a couple of batteries (I do short rides) and I used it for the last 7 years. I have had this set for 2 months.

I love the back light: It is bright and so much better than any other rear light I've used. I get comments on how bright it is. The front light is less powerful than my previous one, but does the job. Keep in mind this is for visibility for other cars, not necessarily bright enough to light the road in front of you (at 75 lumens it's not meant for that).

A note: The light shipped with Mitsubishi batteries. I found these to start failing towards the end of my commute each day on the front light. I thought it might be to bumpy/rough streets, but I switched them out with Energizers and they seem to be holding up better.

Warning: this light is TOO BRIGHT for many purposes. Example: I tried to use it to find something in a briefcase, and the reflected light blinded me. If you hit someone in the eyes with it, they will be blinded. This is bright enough to use as a weapon. I mounted this on an AK-47 with a scope. You can light up a back yard a block away like a spotlight. With a modest scope and this light, it's easy to pick your target. Really, a must-have for a weapon. It's really inexpensive for what you get. But for most indoor use, it's actually too bright.

I am happy with the front light and the tail light - both are great  - it took a couple of minutes to figure out
how to detach and re-attach both lights but now it is not an issue at all.

The pricing was excellent considering the great functionality - good value - just having the ability to detach and re-attach was important. The strobe function on both the front and back lights work great and the lights are quite bright and alert others that you are on the road. I tested the battery compartment openings of both lights and the compartments themselves seem solid and the battery compartment "case" seems to re-attach quite solidly it seems.

There are so many overpriced lighting sets out there that don't seem to have any more functionality than this set - and some definitely have less - ie some have a rubber band type attachments for the light - and who wants that kind of mickey mouse way of attaching the lights? I wanted a strong flashing white front strobing white headlight and a good strobing seat post mounted tail light that are easily detachable and re-attachable and got both in the same package at a great price.

Re front light: I don't rely on the front light totally for extensive night time riding - I don't rely on it for total illumination on pitch black paths or unlighted streets - there are probably brighter higher lumen lights out there for the serious night time rider - but the front light dids help light the way in the few times I have ended up riding home in the dark on semi-lighted dedicated bike paths with periodic street lights. And for the front light the battery saving strobe function in itself provides sufficient illumination. My main reason for wanting the strobe and the front headlight was for its alert function during the day and at say dusk -  to warn others I was coming in their direction with the strobe - and the strobe seems good in daytime, which is when I primarily use it. And I ride on dedicated bike paths. I don't ride on bike paths that are painted on the side of roads next to where cars travel. I don't trust idiot teenage drivers and distracted texters and rushing mothers picking up their kids from school, etc. Frankly,  I do NOT  ride on roads PERIOD.  Given the quality of teenage and distracted drivers these days, who would ride a bike on a road these days, sharing it with cars driven by kids obsessed with their smart phones. It is nuts. I take my mountain bike on either fire roads or on a dedicated separate bike path away from the road used by cars. So this lighting system along with some other flashing lights I have helps warn others that I'm coming. And so far so good!

The Streamlight ProTac HL USB features ten tap programming allowing for the choice of three programs: 1) high/strobe/low 2) high only 3) low/high. First of all whatever you do, do not shine this light into a mirror or onto a white sheet of paper and look at it while the light is on high, because you will be blinded.  I wanted this flashlight because we only have one functioning flashlight in our house.  We live in a wooded area and we find ourselves without electricity more than most people.  We have a lot of trees hanging over the electrical lines, squirrels that try to get warm on the transformers in the winter, its a myriad of reasons so we often find ourselves without electricity for several hours. Therefore, we always need a flashlight. With that said, I had no idea what I had received.  It is without a doubt the most awesome flashlight I have ever owned.  It looks like something a Navy Seal or police officer would carry and probably does.  I was struck first of all by the size.  It is only about six inches long.  I thought, Good grief, what a tiny flashlight, but holy cow the light is out of this world.  It will brighten up an entire room on high.  Even on low, it is amazing the amount of light this thing puts out.  I was getting ready to read the instructions and due to over age 40 eyes and the fact that the instructions are printed in the tiniest print known to man, I used the flashlight to shine on the instructions so I could read them and ended up with a huge black spot before my eyes for a solid minute.  This thing reminds me of the song blinded by the light because that is what it will do.  If anyone ever breaks into your house, simply shine the light into their eyes and you will have time to run or knock them out of the way.  Then I saw the instructions, CAUTION: LED RADIATION-Do not stare into the beam.  When I began reading about programming it, it took me a while to figure out the difference between tapping versus clicking to change the program on the flashlight.  After many attempts and re-reading of the instructions several times with a different flashlight, I figured out that tapping is merely pushing the button not to the point of a full click. I wanted it to be on low.  I don't know why you need it to strobe.  It makes me want to go into a seizure.  Im sure the men out there understand the need for the strobe. I asked my husband but he wasn't sure either.  Maybe if you have a flat tire at night and you want to draw attention to your broken down car, I could see using it for that reason.  Anyhow, you can charge it with the charger they provided or use the USB cord and plug into your computer.  It also comes with a carry case and an adapter to charge it in your vehicle.  I love this flashlight.  I won't have to worry now when we don't have any electricity about lighting candles or lanterns, just turn this on and leave it and you have a fully illuminated room. But, it does get hot and it even has HOT written on the end, but it the instructions say it won't burn you.  The picture attached is in a dark bedroom, shades drawn, door closed, lights out and it is very bright in there.

As noted in the title for this review, I received the 5W version, and it seems very adequate in brightness for some night-time driving, though only just so.  If you're looking for a version of these that will be up to that task, I wouldn't suggest selecting any weaker-powered models.

I really like the tail-light's strobe mode, which really will grab the attention of a driver behind you, though I don't see much use for the strobe-setting on the front light, as that will probably make you so dizzy you'll wreck.  The high-beam/low-beam option for the front light is nice as well.

The beam width adjustment is a nice touch:  the width of the beam is very easily adjusted with the telescoping body.  In the useful range, it appears that the beam width ratio is roughly 1:1.  In other words, at 30 feet away, the beam's about 30 feet wide; at 15 feet about 15 feet wide; etc.  One can easily adjust the width and direction of the beam to cover the entire road at about 30-40 feet ahead of you, and one can adjust the width of the beam to fit the speed at which you're riding, where the useful width might vary.

I also like the ease of installation on both lights, though the tail-light has me a bit worried with its nearly all-plastic mount.  The only metal part of the attachment is one screw (another screw is plastic, as is the entire ratchet mechanism).  The mounting apparatus for the front light is almost all plastic as well, but it is sturdier.

The all-metal construction of the lights' bodies is impressive, as is their weather-sealing.  These look very well made and should last a long time.

A convenience is the rechargeable Li battery in the main light, chargeable via included USB charger.  It would have been nicer, though probably not as size and cost-effective, if the rear light ran on rechargeable batteries as well.  Speaking of size and cost, it would have been simple, though perhaps more expensive, to make this main light smaller and brighter.  I have a much brighter tactical LED flashlight that's about this same size, though it costs about twice as much.  It all depends on what you're looking to save on -- space or cash.

All in all, a nice kit, though, and I'd definitely recommend it.

Like others have said, this is a REALLY bright light. Especially considering its small size and ability to EASILY fit in your pocket. Although the beam is not focusable, this light is very comparable in terms of brightness with my older P14 Lenser. Turning on this light around other people is sure to turn LOTS of heads. Simply put, people don't expect so much light to come from such a small light. This makes the PX25 the PERFECT light to take out on an evening walk in dark places. It's also a good hiking light. Just be sure you bring extra batteries!

Speaking of that, battery life seems to be THE shortcoming of this light. Unfortunately, there is no lower brightness setting to extend battery life in situations where maximum brightness is not needed. Coast says the light will run about 6 hours on a set of AAA batteries. But this is only if you use alkalines and let the light dim to 21 lumens. Speaking of alkalines, I'm actually not too impressed with the performance of alkalines in this light, as the light dims rapidly with use. This is not the fault of the light, though. A quick check with an ammeter reveals that the light draws about .6A. At this point, AAA alkalines are quite overworked (and then some!). MUCH better is to run this light with NiMH batteries - both for sustained brightness AND to save money (since this light REALLY goes through batteries). But if you go out for a hike where you'll be using the light for much longer than an hour, be sure to bring extras. Otherwise, you could find yourself left in the dark!

After fumbling around in the dark with small underpowered flashlights, I decided to try out one of the "premium" lights.  Some friends had spoken highly of StreamLight.  After doing some comparisons, I bought the ProTac 2L.  While I've only played with this a few days, I'm very happy with it.  This thing is Small compared to some others I've had - slightly fatter and shorter than a medical penlight used to check pupils - but the light output is fantastic on its High setting, great for longer distance work.  The Low setting will be useful for shorter distance work.  I haven't decided if the strobe setting will be useful for me but, for now, I'll leave that setting in the programmable switch.  Small Light (size) with Big Light (brightness).  The switch location on the end of the light will take a little getting used to, but I don't consider that a negative.

I'm very happy with this.  My only suggesting for the manufacturer is to consider offering a red filter accessory for this item.

I gave this great headlamp only 4 stars because 5, in my ratings, is perfect, and this one falls just a bit short only because of the tilt mechanism, which I wish were a little more solid in the 45-degree position. However, if used in the straight-ahead position, this headlamp deserves 5 stars.

Its great features make this light a must-have addition for almost anyone who uses any type of headband light, because this headlamp will complement the large super-bright headlamps for close-in work such as work in electrical breaker panels and for outlet & switch replacement.

- Its low-profile design and light weight make it easier to wear & use.
- Its zoom feature is well-placed & very easy to use.
- The dimming control is also well-placed and easy to use.
- Its use of standard AAA batteries means that the average person will be able to have easy access to a supply of replacement alkaline batteries for extended use of the light. (I prefer to use rechargeable batteries that I recharge using a NiteCore i4 charger.)

This light is awesome; it's cheap but fits perfectly on my bike and provides just enough light to navigate through city streets. I would not recommend purchasing this if you plan on flying through dense woodland at night (you'll clearly hurt yourself).

IF you're uncertain if this will provide you with enough light, go to Planet Bike's website and on the homepage click on the "See the light" link. This will compare all of their models and show you the distances the light can travel at night. Overall, if you use streets that are moderately lit and don't want to get hit by cars... don't be afraid to try out the Beamer 3 LED. I was impressed to see the light reflecting off of street signs a decent distance away.

Oh, one last thing! The light is detachable from the mount that you install, so you can just slip it into your backpack (or pocket?) when you're not using it - this prevents theft.

This light is super light, super bright/focused, and will help you set a tent up in the dark, light your path to the biffy, or even let you see your cards for the game you're playing just before sleep.  And they're inexpensive...  buy one for each car, one for the nightstand, one by your keyrack.  They're also great for reading in bed...  just don't make the headstrap too tight :-)

These are really bright and really sensitive, almost to a fault--they practically blind us when they come on. Still, I can't fault a product for doing what it promises. We're working to adjust placement so that they don't shine right in our eyes. Also, the backs of the lights are strong magnets. I didn't realize that when I ordered the, but it's a real bonus. They feel well made, considering the price.

Light works great! Good magnification, no weird lens artifacts, lightweight but with a stable enough base to extend the neck all the way out horizontally. Lights provide a super bright workspace, and the color is as neutral as possible, not super blue like you get with cheap LED flashlights. Focal length gives you plenty of space to work underneath, something like 5 or 6 inches. If the mag was any higher, you'd probably want to use a loupe anyhow. Lens is huge, almost 4 inches, so there's no need to squint and use one eye.

Mine is battery powered (3 AA), although a very kind customer service rep told me that they actually ship now with a power adapter. I find the battery powered convenient, as there is no cord dragging across the workspace, knocking small parts all over the place. However, my experience has been that LEDs tend to gradually lose power at an almost unrecognizable rate. I like to use rechargeable batteries because you can just pop 'em in the oven for a few hours and get the lamp back up to full power.

This little light is a real homerun.

The Good:  Very bright (45 legit lumens) on high with a wide flood beam.  Just right for most uses on low, like finding a keyhole, or looking for something in your glove box. Easy USB recharging.  Adjustable brightness is nice.  Switch functions are perfectly thought out.

The Bad:  I found I prefer the black model over the clear one.  The clear one lets so much light out of the light body that it slightly upsets my night vision.  This is not a big issue, and is easy to avoid my holding the light deeper between my fingers.  This is a non-issue with the black model.

The Final Verdict:  The light is basically perfect for its intended use.  I no longer carry any other keychain flashlight, as this light is tiny, bright, has a long battery life, can be recharged in my car, at my house, or anywhere there is a laptop or tablet around.  The price is awesome too.  15 years ago, this would have been seen as Star Trek technology.  I keep one on my keys, and have another on the zipper pull of my ski suit.
