Lumintop B01 USB C Bike Light, Rechargeable Dirt Bike Headlight for Night Riding, 850 Lumens Anti-Glare Bicycle Headlight with 216m Range, Road Cycling & MTB Light, Low-Power Warning, IPX-8

I love this light. USB-C rechargeable and you can easily take it off to do other things like look for your dropped keys in the dark or pop it off to check your tires. I bought 3 more.

My favorite light! I have 2 of them on my bikes and I also use them when camping. Recently my wife lost one and I bought one more. None of 3 lights ever had any issues.The most reliable light I have ever had. Waterproof and no issues with strong vibration in mountain bike or occasional dropping. I usually use medium brightness setting riding in the woods after dark.The mount is very sturdy and holds the light well. I feel confident riding downhill fast. At the same time it is easy to take the light out of the mount (just pull hard).I use 21700 battery in it. Enough for multiple hours (probably for all night). I always have a charged second battery with me, but never had to switch the batteries while riding.

The retention strap is made of hard plastic and broke before I could ever get it onto my handlebars.

I've ridden at night for 30 years. This light has a perfectly shaped beam for night bike riding: wide oval, with a secondary beam downward just in front of the front wheel. The middle setting compares favorably to a single headlight on an automobile in illuminative power, and provides several hours of light. Further, the lamp projects a warm, natural light that makes it easier to interpret what the rider sees, as compared to some of the blue, cold lights of other lamps. My favorite bike light. I own two so that I have a backup in the unlikely event I need one. I love riding at night, with the right lighting.

So far the product is holding up pretty well. It gives you about at least 30 feet infront of you. Keep in mind I'm wearing ski googles because I can't find any motorcycle googles that fit my head and these are tinted and they still give me very good visibility. I knew Lumintop when I was looking for laser photon flashlights and they seem to reliable with those.

After trying it out, and experimenting with mounting, I decided to return it. It would have been more useful to me if I wanted to use the light off the bike, but I don't, and overall it feels "chunky"I returned this, and instead purchased an admittedly more expensive Cygolite Metro 1200, I am much happier now

This is a really good light, and it has a warm tone instead of a super white beam. It's easier on your eyes and still illuminates the road more than well enough for any speed a bicycle can achieve, and since it has a cutoff for the beam, drivers aren't blinded by it. My minor complaints about it are that the power button is a constant battery drain because it never stops glowing unless you loosen the battery cap a small bit. I personally like to use a multi-port charger for batteries, and the end cap of the flashlight's battery often crushes in on itself and prevents my charger from engaging. I know most people will charge with a USB cable, so this gripe is niche and personal to me. You'll likely need to find a better mount for your bike, as the included mount is doing the bare minimum. Any spirited riding at all will cause your flashlight to slowly rotate downward at your wheel instead of the path in front of you. All in all, it's expensive but a very nice flashlight that doubles as an excellent way to illuminate the area in front of your bike for night riding. I'd purchase it again, but still find myself wanting something better. Unfortunately there's not really much better for the money, I won't spend hundreds for a bike light.

This light is well made and works as advertised. My only complaint is that the built-in battery charger does not charge the battery fully - I have to use an external battery charger to accomplish that. Otherwise, the light is just about perfect for me.And in response to other reviews that complain that the switch's back light is always on, you can disable this by pressing the switch quickly 5 times when the light is off (it's in the manual ;)).
