High quality, low price.
I got this light for my e-bike, and it has surpassed my expectations. To start, I did not charge it out of the box, I just installed it and ran with it. The light lasted from Monday until Thursday for 40 minutes per day. Not bad for right out of the box (Possibly 75% charge on it). The mounts are very sturdy and do not shake when I hit bumps, even the gnarly ones we all try to avoid (which I sadly hit, A LOT. lol). The mounts also fit multiple size bars, and come with a few bushings to make things nice and snug. The light housing has a nice weight to it, and the light is decently bright. Definitely bright enough to feel safe and visible riding down the road. It’s nice when I have cars bright light me when I run it on Medium (low beam and spotlight together). There are 5 light modes, 4 of which I have included pictures for. (You know you love my Halloween decorations!) It has low beam, spotlight, high beam, flash, and daytime running lights. 10/10 would recommend this bike light!

Great secondary light for E-bike.
So far so good! Light is pretty bright and easy to install. Could only use one bracket to attach it to my E-bike handle bars but is held in place just fine. Battery seems to hold up well with Midwest winter.

Uncompromisingly bright
This headlight is supremely bright. The high beam of biking, without question. If you want an uncomrpomising illumination - this is the one you must get. However, it comes with some limitations. In some circumstances, it will overheat, especially if it is very hot (above 35C/100F) and you don't provide it with enough oncoming air. More importantly, it's charge will rarely last more than a day worth of biking, considering how energy-intensive it is. When you are charging it you will soon discover that it fails to deliver a clear feedback about it charge status - it doesn't shine any light when it is being charged neither does it provide any feedback as to how much charge it has accrued. Additionally, while it is easy to install, you will probably find yourself needing to remove it often to charge. Its railings however will catch and get wedged very easily at the slightest misalignment and you will find yourself having to angle and jitter it quite a bit until you can slide it out. Were these issues addressed I'd give it 5/5 and even 6/5 without a moment's hesitation even despite its intense energy consumption. At this moment though, even as I hold its function to a very high standard, its lack in user-friendly interface and ease of serivce makes me only give it 4/5. If you are not iffed by such sensibilities and even if you are - get this one, you won't regreet it a bit. All things considered, it is supreme to most competitors I have used.

XSmall Pro works as helmet mounted light
It is not clear from the product description but the XSmall Pro mount is compatible with any mount that is also compatible with Garmin bike computers. Also the light comes with an Allen wrench that can be used to switch the mount to the bottom of the light so that when mounted on the top of a handle bar or on a helmet the high beam is actually higher than low beam. I was hoping I could use the XSmall Pro on my helmet. Luckily another company makes the Magicshine Helmet Mount Bracket which is compatible with the XSmall Pro. The mount works better than I hoped. I just got the light so I can't comment on the battery life yet, but I am very happy to have a cheaper bright helmet light.

Great but has some flaws
First off, I want to say that I genuinely like this light. It's very bright, when my girlfriend is on her bike (we each have a the same light) I have no trouble seeing her coming towards me from quite a distance, almost looks like a motorcycle coming towards you. There are some flaws though that I would like to see improved in the future, or maybe just a different light for me. To turn on the "high beam" you have to hold the power button for a few seconds, this will activate the high beam. Problem is you have to hold it again to turn off the high beam. Even if you turn the light completely off, the high beam will stay on. There are quite a few different light modes, all seem a bit unnecessary. For the vast majority of people they are going to turn the light on, use it, then turn the light off. It would be nice if there was another button on the opposite side to cycle the modes so you could easily turn the light on/off. Instead to turn the light off you have to cycle through each mode until it turns off, and hopefully not press the power button one too many times, as you'll have to cycle through them again. Finally, and this is kind of a 2 parter. The light has no warning indicator that the battery is low...it just turns off. It'll last a few hours on though, so for most people this probably isn't a problem. I tend to ride my bike around 3:30am for around an hour every morning. I don't charge it everyday, as I don't need to. However, once I get to my longer ride on say a Saturday morning when I don't have work, I'll do a 3 hour or so ride and this is when it tends to die. You can turn the light on again and it'll stay on for about 5 seconds before shutting off again. It'd be nice to have an indicator on top to easily see how much battery you have left. Oh, one more thing, this light is fairly big. Putting in on your handlebars, depending on how your cables are arranged it can be a little tricky to take off and put back on to re-charge (which is another inconvenience), but not going to fault it for being rechargeable. Final thoughts: Even with the minor flaws, it is a good light, it lights up the streets of my neighborhood and anywhere else I may go. I would like to see some improvements for quality of life purposes. I probably wouldn't buy it again knowing what I know now. If they make another version though, I'd be all about it. The build quality is superb, it feels sturdy, not cheap feeling at all. I don't recommend it, but I also wouldn't fault anyone for getting it and enjoying it. Just not for me.

Una lampara que ilumina muy bien, se asegura en el manubrio y queda bien fija, no se mueve nada, no encontrarias una lampara que ilumine igual que esta a menor precio, el unico detalle es la duracion de la bateria, si vas a una rodada nocturna mayor a dos horas se empieza a descargar rapido, pero en rodadas cortas funciona super bien. es muy practico que la entrada del cargador sea USB tipo C

WIRKS GREAT AND VERY BRIGHT

First of all, it is a good bike light. It does lived up to its reputation of being very bright. However, the light died just after one use and attempts to charge failed. I would advise against purchasing this light until the quality can be guaranteed.

First MTB ride this morning in the dark and its very good. Fits secure, very good visibility, wide range and the 1 hour ride on full power still had 3 bars on the indicator. I will not charge yet and see how long it lasts but first impression is very good.
