4800 lumens is no joke!
This light is about as bright as a quality car headlight out in the woods, and with 3+ hours of run time on high (and 7+ on low). Honestly impressive for the money. Good weight, and ease of charging with USB-C, including a percentage indicator. The mounting clamps are fine and with just 2 thumbscrews, you can quickly slide it on and off the mount "channel" that they go into molded into the light's case itself. All my friends are always surprised how bright it is when I turn it on out there. It's really all you need and nothing more for a bar light. This stuff has come a *long* way since I started night-riding mountain bike trails 15 years ago, but I actually prefer these smaller-name models more than the theoretically better-supported, overly expensive names, as the build quality is excellent and I've yet to see any of these tough modern outdoor-rated LEDs burn out. Now to find something this impressive for the helmet mount... that's another story! :)

Amazing light that won’t break the bank
This thing is awesome! I’ve taken it on many many rides in the cold rain and mud and it still works great. I love the battery timer display too. This light is better than many of the other mountain biking lights my buddies spent $150+ on. Highly recommend this if you need a light that has amazing battery life, great illumination and won’t break the bank. I’d choose this over the expensive lights any day of the week. I get compliments on it from lots of other riders. It’s a hidden gem.

Beyonx expectations
Beyond expectations. I just wanted a basic light but not too cheap. I also like the digital read out. After seeing that feature I wanted to buy it. And it's awesome. The brightness is way brighter than expected. Highly visible during the day even on the lowest setting! Added this to my Altis Delta. Fits perfectly. I've done jumps and trails and hit 64, and still stayed in place. Worth every penny

Great light, super bright and heavy duty
This light is super bright and it’s made of metal, seems like it will be super durable. Come with a full charge ready to go, can’t attest to how the charge holds up on it but everything else is superior for the price. Highly recommend

Good light, misleading description.
Decent light but gets a 4 star rating because of the misleading description and mounting method. First off I wanted to test the light out in a few different ways. I ran the light on max brightness for about 60 minutes sitting on a cardboard box to check the temperature of the casing. I installed this on my e-bike and wanted to make sure it wouldn’t get too hot touching other wires. I ran it for 10 minutes then took the first photo, it was at 108 degrees then 40 minutes later the lights temperature topped out at 118 degrees, ran it another 10 mins and it didn’t rise in temperature. I used two separate devices to check the temperature and it’s absolutely correct (used a nice fluke meter also). 118 feels fairly warm in my hand but not enough to burn. I also ran a timer vs the display timer. I’d say the lights display is approximately 10% faster than real time. So it’s close enough and of course this is going to vary depending on use, temperature, charge. So that’s fair. Now the cons are it’s definitely not 4,800 lumens. I knew it wouldn’t be when purchasing but the light is pretty bright so they really don’t need to inflate the numbers like this. The light is plenty bright for a bike. I don’t think you should put this on a road going vehicles. It would definitely blind anybody oncoming. (Light is to scattered even on spot) I have mine pointed just a few feet I front of my tire and it really lights up at a distance. I have some quality well known and more expensive lights to compare this to. So I’d say the flood and spot light are close to about 800-1,000 lumens. Full brightness is probably closer to 1,200-1,600. And for context my 1,600 flashlight can basically shine down the block that’s about 2,000 feet. This light has much more flood light than any flashlight I own that is the reason I got it. My bikes headlight is narrow. Good for night rides when there’s street light but I needed something for pitch dark in the woods. And then another con is the mounting screws/channel that the light slides into could be better. They have plastic end tabs so you can only tighten so far by hand. This is probably by design but I feel they could have done something different so it was a little more secure. I think I’ll have to keep checking those screws to see if they hold. I did gently use some pliers to tighten them even more but you need to be very careful with this. I’m not recommending anyone do this because I can see it stripping from over tightening. Also if you just wanted some backup extra power to charge a cell phone that could work. So overall fair price, it’s pretty inexpensive for the amount of light you get, just don’t expect the numbers they advertise. But it’s plenty of light for my e-bike doing over 20 mph in the dark.

Rekommenderas.
Mycket bra lampa för priset! Provade den för första gången dag, jag har den på min bebis barnvagn när vi går promenader i skogen. Jag kan inte svara för antalet lumen men den lyser på bra. Jag har några ficklampor på 2000 lumen sedan tidigare (bland annat Olight) och denna är mycket starkare, även på lägsta modet. Enkel att montera, känns som en bra konstruktion, finns 3 olika distanser, 4 om du räknar med fästet i sig. Det finns två plastdistaner och en gummipackning, jag har valt att använda bara fästet och packningen. Trots att jag kör över lite rötter och andra ojämnheter sitter den still och rör sig inte om inte vagnen rör sig. Batterinivå syns tydligt i displayen och jag upplever att den är rättvis med antal timmar och minuter som har gått. Levererades med 97% batterinivå, uppskattas om man som jag är otålig och vill prova den igår. Rekommenderas!

Supper bright Bicycle Head Light
No lies told. It was super bright, even on the lowest setting. I can certainly comfirm, it is definitely brighter then some cars head lights. The warnings are reasonable. Supper blinding, don't shine it directly onto someone's eyes. I tested it out for myself and can comfirm. Mounting it onto the bicycle wasn't difficult either. What I love the most about this product is the battery life spam. An entire shift long (perhaps longer) if used on lowest setting.

No dejes pasar está oportunidad
Muy buena iluminación, bastante luz, quizás si se calienta un poco pero nada que perjudique su funcionamiento o moleste y la batería me dura alrededor de 6 horas. Si lo que buscas es iluminación al salir a pasear está estu mejor opción.
