ugoe NB13-01 Ultra Powerful 3000 Lumens Rechargeable Bike Light, Waterproof LED Headlight with Li-pol Battery Pack, Compatible with All Bike Types

I am one of those Nerdy guys who custom retrofitted a full-suspension, racing mountain bike with a 50cc 4-Stroke motor for commuting to & from work and getting light errands done. On surface streets I am clipping along with traffic pretty well but the law in my state favors my still playing by "Bike rules" despite the motor: bike-lanes, passing on right, etc. For the shoulder seasons and particularly at times outside of daylight savings I needed a light that would allow me to see far enough ahead to still see sticks, glass, potholes or other hazards coming at me even at my higher average speed (than a conventional bike), particularly in total darkness. Not only does this light succeed marvelously in that department but also the flashing-function, for use during daytime or inclement weather, REALLY gets the attention of drivers! I never totally realized how often cars pulled out from side-streets in front of me or took sudden right-hand turns across my way when I'm near them in the bike lane. I realize it NOW though, because those occurrences have been reduced almost to zero! The light illuminates reflective sings WAY far ahead too!Some reviewers have knocked off a star because they say it gets hot when used at max brightness. After a month of use I have not noticed it ever getting intolerably hot (though I do tend to wear light gloves). My only "concern" is that I suspect the battery may not hold a charge for quite as long as they say it does (at time of posting: 6hrs on high - now, 2018 they say 2hrs and that is a very low estimate) but I am still testing that out: power may still drain slowly when the light is hooked up but NOT in use. Example: Battery was on charger for 5hrs on a Thursday night. Hooked up light on Friday AM and used on flash mode for 20min. Battery still attached throughout day with light off. Home commute light was used 10min on medium and 10 on high. Bike sat in garage with light off over long weekend-- battery still attached though. Tuesday AM I turned on light for morning commute and had the low-power flash indicator & red-led going. That's 20min on flash, 10min on medium and 10 on high of actual use and off for ). The battery still gives at LEAST an hour at max level, which is more than I need most of the time.I echo others' warning that this lights is indeed very bright- comparable to a car's high-beams. It is very easy to be courteous to drivers though, just rest your hand on your light or bars over the light and block the top half of the beam (when safe to do so) with your hand. Everybody wins.Neither the alleged heat, my personal suspicion about the battery or certainly the satisfyingly bright capability if this bike light is significant enough for me to remove ANY stars. Bottom line is that this light has totally enabled me to continue to use my bike well after the sun has gone down and with nearly as much confidence as I have in the daytime. And, even in the daytime I feel a heck of a lot SAFER! (In bridge photo light is on set on #2 medium. In "Rural" picture it would be black as pitch if I had no light, setting is at max: photo does not give total justice to how well you can see in that environment.)

The bike light is okay, but the only problem is that i did not like the size of the battery. Its not a reliable size for your bike especially when you are out there on the streets and you go somewhere for an errand it can possibly be stolen by someone easily. The size of the battery is ridiculous!

Selam,I was really reluctant to spend this much for a light and know I should try to save, but saving my life is important, too, so I said to myself--especially after some near hit misses. In any case, I always prefer paying extra for quality than not so I did. I'm sure some of you are in that boat. Overall great lights, no issues so far. I've always charged it the night before using it so I don't have the exact hours, but the battery seems solid. Enough light to get me out of a pitch dark park trail and though I'm one to want even more lights during pitch dark nights, I think it would be illegal for it to be any brighter as it might be harmful/blinding to some pedestrians. Good visibility as I commute to work during the day as well. I still have not parked my bike somewhere and driven around it to see how visible I am to cars during the day under the bright sun, but I'm sure I am visible since cars stop just before cutting me off. It does get hot on high beam quickly but I've not had it on for long enough time on high to see how hot it really gets and if in fact it might be dangerous to touch. I've seen other lights claiming more lumens capacity than this at a cheaper price and wondered if I should've been more frugal after making this purchase but a quick glance at the costumer reviews suggest otherwise. I hope this helps, I don't usually write comments. With love.Ps. I have a "BM WORKS Speed Extender" to conveniently mount my light and battery back, in case you're wondering. Ride on, cheers!

The first light lasted just over 4 months at about 12 short commuting trips per month. Not even 20 hours of usage before failing to charge anymore. The replacement light lasted about 6 months before failing to light even with a full charge. When it worked it provided great visibility but reliability is pitiful.

This little bike lamp produces and incredible amount of light. I use it during the winter months to ride the pitch black trails of Dana Point and the Luge. It lights up the trails really well. I have it mounted to my helmet with the battery pack strapped to my hydration pack. I would give this 5 starts if the battery life was a little better and the light didn't get so hot.. it gets REALLY hot when used on full blast. Great product for the price tho.

So I like the light it is very bright it has a great design. I have bought many lights for my bike but this one is the best. But I would of gave it 5 stars but theirs 2 problems 1 it gets very hot in about 4minutes on bright wich most lights do. 2nd problem is that the light only last about 1 hour on the brightest mode. I thought it was supposed to last about 4 hours because that what it said.😕😕😕😕. Besides all that it's a great light I would recommend this light but if u do choose to buy it I recommend a second battery pack. I hope this post give u the information u need. Good luck😉😉😉😉😉😉
