the bike lights works great the batteries last long time I'm very happy with it
They work very nice, very bright for night vision, easy to use. I recomend this item for someone riding in the city and dark streets.
Great Light soild just need to test underwater but so far so good
Still alive after four months of outdoor use. Super bright, I use it for an all night light sometimes. Still going in the morning just gets dimmer
Works great. Plenty of light for mountain bike night riding. The battery has lasted for every ride, maybe 1.5 hours max so far. I always ride with 2 lights on the way down in case a light goes out, use this light as my primary.
love it ts powerfull like hell
Indispensable for me was the digital current output, which in fact works very well. In the brightest mode, the amount of light is similar to the one of a low-beam car headlight.
Concerning such a bright LED light in such a small body, heat dissipation is always a problem.
For this bike light, it is solved by an overheating protection circuit which turns the light to the lowest one of the three brightness modes when it achieves a certain temperature. After the system is sufficiently chilled, it returns to the previously used mode.
As the lowest mode is a lot dimmer than the "mid" mode, it is not sufficiently bright for me. So I would prefer a better heat dissipation system (it would not be any problem if the bicycle light were bigger).
In the future I will probably buy bike lights without protection against overheating and put up with the higher sensitivity.
Nice bike light. Good value. Very fast delivery. Could buy another one.
