Waterproof 700 Lumens LED Bicycle Light 4 Modes Super Bright Bike Lamp Headlight + 8.4V Rechargeable Battery Pack + Charger for Camping, Cycling, Hiking, Riding

I needed a bright light for night rides on dark streets at 20+ mph. This one looked like a great value. I was a bit worried about the battery given the mixed reviews. This review is based on my first ride with the light. I will update after I get a few rides and charge cycles on the battery. First, I was impressed with the retail box, fit and finish of the light. looked professional and well built The battery looked good too. the battery bag seems a bit flimsy but had no issues with it on the first ride. I received the unit, and promptly charged the battery. the initial charge took almost 4 hours. Just in time for my evening group ride. I mounted the battery under the stem and hung the light under the bars just to the right of the stem. I mounted my old light on the left side as a backup. I coiled the extra wire with electrical tape then attached it to the side of the stem with more electrical tape. I know it was kind of getto, but I was in a hurry. I need to get some velcro cable ties to do it right. I also left just enough slack to allow me to leave the cable unplugged because I didn't want the battery indicator lights on the entire drive to our meet up location. Did a quick test and all 3 power levels and the blinking function worked. Started the ride on medium power because I didn't want to drain the battery too fast. It was plenty bright on the streets with street lights. On the first block I noticed that my combination cadence/speed sensor wasn't registering on my cateye stealth 50 (more on this later). I tried to reach down and tap the unit at a signal light but still nothing. Rode on with the group for 35 minutes and regrouped for a couple of minutes. I knew we were heading into unlit streets so I pressed the button once to go the high power. We rode for another 30 minutes and regrouped, this time for 10 minutes. I shut the light off to save the battery at this time. I had 2 green lights still on at this point. Turned the unit back on high and continued on for another 35 to 40 minutes. At the end of the ride there was one green light on. I got 30 minutes of medium and over an hour of high from the battery. I was curious how much was charge was left so I turned the light back on high when I got home. I left it on for another 15 minutes before I shut it off. because it was getting too late. I was really happy with the light so far. Its really bright, especially on high. I can't speak to the claimed lumin output because of I don't have another light that comes close to comparing it to. I do know that other riders have the same light and also the single bulb unit that goes for 20 dollars and the output is the same as the others. Of course its brighter then the single bulb unit. More on my computer malfunction. I read another review about interference with the sensors. I didn't remember to check it out until the next day. I checked the battery on my cadence/speed sensor and I confirmed that it was sending data to my computer. I put the light and battery back on my bike and turned it on. Everything was working normally. I have been having intermittent problems with the sending unit, so am not sure if the light is causing or making it worse. I will update when I figure out the problem and also see how the battery and battery pouch holds up over time. All in all, a great value and a great light.

Great light!. Construction seems to be high quality. It is constructed of alluminum metal and appears to be very durable. It comes with a battery and charger,t and two heavy duty rubber bands ( two sizes). The handle bar mount is a real simple low-tech system that works extremely well and it is really easy to install. All you do is rest the concave base of the light so it cradles the curvature of the handle bar, stretch the rubber band and attach it to the clips on either side of the light and you are ready to go. The concave part of mount that sits on the handle bar is rubberized so the light does not rotate down from vibration while riding. So far I have used this light on some mountain bike rides and have also mounted it on my head while doing some wiring work in my the attic. I hope to soon take it camping with me. On my mountain bike rides, I have used the light on the handlebars and also on my helmet. I personally prefer the helmet mount for my mountain bike rides, especially when riding on twisty single track. By mounting the light on my head, it allows me to shine light where I’m looking, allowing me to see the trail clearly around the turns. For the best illumination possible on the trails, you ideally want a light on your head and a light on your handle bar. However, this light is sufficient all by itself because of the amount of light it puts out. The output is incredible! It is brighter than many of my friend’s hundred dollars lights and much easier to install and remove because no tools are needed). I have used the light on the high setting on all the rides. Our bike rides always last about two hours and the light was still shinning bright when we got back to the cars. I was also mounted the light on my helmet using the supplied rubber bands. My helmet happens to have a rib across the two center vents on the front of the helmet that were the perfect location for the light. For some type of helmets an additional helmet mount may be required, but any universal mount with a cylindrical shape mount would probably work.

Extremely bright light, most light is focused towards the middle, while providing a very wide bright ambient light. I don't know how well or long the battery pack will last, and it would be nice to have a full power-cut off switch (so you don't have to unplug it to prevent the led from draining the battery). The strobe feature is an ON/OFF type, not a Dim/Bright type strobe, which is why I have given 4 stars instead. Controls are super simple, it cycles between low/med/high/off with each button press, or if you press and hold it will activate the strobe. Makes a great primary light for riding at night, whether its on dimly lit roads, or deep in the mountains biking the dirt paths. The strobe feature is good for daylight visibility. --------------------------- If your going for the long haul, or spend most of your time biking at night, I would recommend this combo: 1. Cree T6 USB: http://www.amazon.com/gp/product/B00GFLQMAK/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 2. TeckNet 12000mah Dual USB Battery: http://www.amazon.com/TeckNet%C2%AE-Dual-Port-Lightning-Sensation-Blackberry/dp/B00FRDEJN4/ref=sr_1_8?ie=UTF8&qid=1411847686&sr=8-8&keywords=tecknet+power+bank The light is extremely bright too (not as bright as this one, but more than adequate), its strobe is dim/bright, the battery pack is a 'shake to wake' means it auto-shuts off when the light is off (so the led doesn't drain the battery) when you stop riding the bike, and can be used to charge any USB device you might need. It is a brilliant combo. --------------------------- Conclusion: With either of the lights/combo's I have a significant amount of light at my disposal. I prefer the Dual U2 LED as my primary, and the other one as a strobe during the day/night, and between both of them, have enough light (depending upon usage) to bike from sunset to sunrise wherever I am safely. P.S. For anyone looking at purchasing LED flashlights / bicycle lights / utility lights these days, that are listed as 'Cree', the model Q5 < T6 < U2 in regards to technology. Also don't believe the Lumens most sellers advertise as those are 'maximum specifications' for the LED's when their overdriven to capacity, and not actual light output of the product in most cases (if the seller isn't just blatantly lying).

This light is so bright! My last bike light was a PlanetBike 1W. I would need ten of those lights to get something with this kind of output. It's even brighter than the Knog 5.5 while still achieving a decently wide beam, though not quite as evenly distributed. Overall the beam throw, width and distribution is pretty good. It's as bright as the Niterider Lumina 650 but doesn't throw as far. It's wider than the Knog 5.5 which is wider than the Lumina, but the light isn't as evenly distributed. It's more evenly distributed than most lights in this range, though. It's not really the best in any one specific area, but it's the best overall between all areas's without spending $80-$120 for a similar light from more reputable brands. It was a risky purchase given all of the reviews across multiple brands that offer this same light and it's unusually low price tag, so I guess I am one of the lucky ones. At this price point it was worth the gamble I felt. Most people are reporting issues with the batteries rather than the light itself, so I felt that if I received a defective battery that I could just buy a new and better one to replace it and still end up spending less than what the more reputable brands offer. My only complaint is that the light does get near burning hot to the touch if there is no airflow moving across it. That was only after 45 minutes on it's highest setting. However, even a slight breeze cools it off pretty well, so I'm not concerned about it too much. At night with cooler temps with a bit of airflow just from the movement of your bike, it should be fine. If there's a slight breeze on top of that, I don't see that there would be an issue. During my battery tests when I was experiencing the heat problem, I ended up hanging it over my office fan on it's lowest setting, which is just a gentle breeze, and it's was nearly cool to the touch almost immediately afterwards. As far as battery life goes, I've been timing it on it's highest setting. So far I'm almost at three hours, which is very unusual. I'm guessing they sent the wrong battery with my model, because many people are reporting times that are nowhere near this long. I've checked the brightness setting multiple times just to make sure it's on it's highest setting and it is. Pretty odd. Not that I'm complaining! At the time of this review, the battery indicator led's just dropped down to 1 of 3 lights and is starting to blink with the light dimming a bit in correspondence. So, for the set that I received, I'm gotten about three hours worth of usage on it's highest setting. Maybe these aren't the right LED's? Regardless, it's still very and more than adequately bright so I can't complain. Pros: + Price + Very Bright + 3-Hour Battery Life + Sturdy Aluminum Body + Easy Bike Attachment Method + Screw-In DC Plug + Water Resistant Cons: + Attachment Method Not As Sturdy As Other Brands + Light And Battery Not One Single Piece + Very Hot Without Airflow + Quality Control

I purchased two of these light nearly 1 year ago. I held off reviewing them because I didn't know what to expect: So after 1 year, zero issues with the lights themselves; but like its been said by other reviewers... do yourself a favor and buy a quality battery, or even better: build your own. The original black packs on mine didn't last more than a couple months IIRC. Both chargers have lasted this long and keep charging pack after pack... so, knock on wood. After getting them back in July 2013, I commuted using them nearly every day for 3 months without any issues... 13 mile commute one-way. Then winter set in and I didn't ride anymore but decided to open them up to modify them. One of the lights was upgraded using x2 warmer color ~4500K XM-L2 emitters and the other one with a combination of the original XM-L but de-domed and one XM-L2 emitter. The second light throws really far away with a really nice pure white color; I use that one on my helmet and its arguably the best bike light I own. And the other one puts out a warm floody light so I've put that one on my handlebar. As for the claims of 2800 lumens, probably 1200 at best. To compare these, I've just purchased an EagleTac SX25L3 with the MT-G2 emitter and my bike lights, even after being upgraded with XM-L2 emitters, they are dead even with the 1220 ANSI lumen setting of my SX25L3. Now, setting the SX25L3 on max (2750 LED lumens) it outshines these bike lights by an ample margin. It is a good bright light that is affordable, but don't forget to factor in the cost of a new battery pack. Also, I strongly recommend upgrading the LED emitters with warmer color ones.

This is SUCH a great value for the price. I've used this light on my 35 minute commute on Seattle in the dark and foggy mornings and the completely non-lit bike trail. Charging / Battery Life : First setting on the ride in, second setting on the ride home, and I still have battery when I get home (though I do recharge every night). Definitely beats replacing two batteries ($10) every so often for a not-so-bright light. I disconnect the light and the battery pack when I finish riding so that the LED won't drain any power, though I probably wouldn't have to. Design : As some other reviewer said, it totally reminds me of Wall-e ! The metal casing looks like it could take a beating -- though it is very sharp on the edges, so I wouldn't want to whack into it. The push-button has a satisfying tactile "click" (though I wish it had an up / down settings adjuster, so you don't have to turn the whole thing off to get back to go from setting 2 to setting 1). I currently have the battery pack fastened to the seat post with the cord wrapping around the frame. I had a blinking light on the seat post (silicone knog style) and at some point during a ride the battery pack bounced up and knocked the light loose. It would be great it the battery pack had a second velcro attachment so it would be more secure. Might add my own. The connection between the battery pack and light has an threaded sheath so that they won't disconnect on a bumpy ride. Brightness : I've had a couple complaints (using the second setting! ), from other riders even though I make SURE to point the beam toward the ground so that it won't be at eye-level. "That light is REALLY obnoxious" from someone I was passing from behind and "Turn that DOWN!" from someone I was passing head-on. I've seen much more annoying shockingly bright flashing lamps, and I wonder if these snippy people aren't just crabby. It is really nice to be able to see roots and potholes and cracks in the pavement before your front wheel hits them--why else would I bother having a light? If it's a well-lit area I knock the brightness down to the first setting, and wouldn't use the third setting unless it's pitch black and there are NO oncoming riders. I highly recommend this light to anyone who has a dark commute-- just make sure to turn your light toward the ground, and prepare yourself for snippy comments anyway!

I'm kind of surprised that I'm the first to review this item. I've read the negative reviews on the various 3 diode lamps offered on Amazon, and really took note that the battery life was severely diminished when set on high. It was also stated repeatedly that the difference between med & high (2 vs 3 led's) was minimal at best. It was also suggested that you need to buy a diffuser lens with the round, 3 diode light. All of those concerns made me take a second look at this light. It has 2 separate housings for the led's, spaced apart. I figured the light pattern would be wider, and no wasted third diode. The 6400 mAh battery pack seemed to be a nice upgrade from a lot of the ones I looked at too. Reliability was also a big complaint, so I made myself wait to write this review, to make sure it wouldn't crap out right away. I've owned this now for @ a month, and all I can say is that it is excellent. I use it 5 days a week, for a 45 minute ride into work in the morning. It has performed beyond my expectations. I haven't had a single problem. It is very bright, probably more than I need when set on high. Low and medium are more than enough to give you a clear view of the road coming up. The light pattern easily illuminates a standard two lane road out to 25 yards. I ride along a pitch black trail for about half of my trip, and I never feel like I wish I could see more detail, or further ahead, this is at @ 15 - 20 mph. For an urban commute, I can't imagine another light system being any better than this. It seems to be sturdy enough to handle any sort of terrain. I highly recommend this light!

The angle of the light is atrocious. You have a bright spot barely as wide as a bike lane which abruptly cuts to a dim circle beyond that. Useless to see anything not directly in front of you. Watch out, stray cat! The mounting is a joke. In light rain it will easily slip and you would need to point it the right way after every tiny bump in the road. The wiring is the worst I've ever seen. Within a few weeks, it stopped working. I dabble with electronics so I figured I'll take apart the battery to see what's up. I've never seen a worse soldering job in my life. Even my first time soldering held better. One of the wires just fell right off the battery. Plus zero strain relief for the wire going into the battery. I fixed it and it hasn't broke again since...at least the battery that is... On to the charger. Now THAT wire is being finicky. I have to constantly play with it until the friggin red light finally comes on showing that it's charging, and pray to whatever god you believe in that I can put it down and let it go without it going out again. Don't let that thick wire fool you. Inside is the tiniest 2 wires you will ever see in your life. I refuse to fix this light again, I'll just buy something else. DO NOT WASTE YOUR MONEY!!! Oh yeah, at least it hasn't died in the rain. That being said, from day one I didn't use that battery holder it comes with. The battery has no protection against water whatsoever. Just shrink wrap, and the ends are cardboard. If you DO buy this worthless POS (which hey, if you like wasting your money, be my guest) keep the battery somewhere that will never see a drop of rain.
