Best Bike Lights 2600 Lumen, 5 LED Bicycle Light with High Beam Low Beam, Best Bike Lights for Night Riding, USB-C Rechargeable Bike Headlight, Waterproof Bicycle Lights, Power Bank Function

When I first got this product, I did not notice that I could use the thinner plastic inner-ring in order to secure it to the centre of my electric mountain-bike, but, managed to figure it out on the second one.This product comes with both a thick and a thin inner plastic-ring since different parts of the bars on a bike will either be thicker or thinner; use the appropriate ring to be able to tighten the clamp properly.I mentioned, and, recommended getting at least two of these head-lights, but, a total of three is probably optimum, for one bicycle. Why two or more for one bicycle ? The lights have four activation-modes... they look like as follows...:[+][-][+][-][+][-][+][+][+][!][!][!]The + representing that the bulb is activated, the - indicates that it is not activated, and, ! is a blinking effect. Now, here is the main reason why you want at least two, because, you can actually use the blinking mode like a turn-signal; note that this will only alert who-ever is in front of you, but, may be visible or noticed by even those behind you if it is at night-time, although, I have not tested this out yet;I got my 2nd in yesterday and installed it earlier this morning, and, I should mention that, because I have an electric mountain-bike, I was not able to mount both of the lights that I currently have to both sides of my handle-bars in an aligned manner, due to my gear-shift deal being in the way, but, I did manage to get them aligned in a manner where I have a light on the left and the other light in the centre-right (or how-ever this is supposed to be described; in any case it is close to the centre, but, a bit to the right as shown in the image from the picture I took for it for this review).I plan to get a 3rd one of these head-lights, and, now that I know about the inner plastic-rings options, I know that I can mount it to the portion that I have marked with the golden-circles; sure, this might seem like going a bit over-board, but, this is definitely a worth-while product !I don't have anything to say about its water-resistance at this time since I do not typically go anywhere in the rain, and, I also always keep a water-proof cover over my mountain-bike when not in use so that the rain does not get it wet (boy did I wish I got it sooner rather than using a regular tarp for over a year which didn't guarantee keeping the rain out). I thought I had another thing I wanted to say about this product, but, cannot seem to think of it at this moment; how-ever, for someone with an entrepreneurial-mind, this is the kind of product I would be proud of including in my line of products as a business that sells it if I ever decided to become a part of this industry (I have other ideas for now, though, such as getting the leg-work set-up to eventually be able to quick-cultivate algae for bio-fuel in order to compete directly against the oil-companies, and, perhaps even force the oil-prices to go down since none of us in our right minds could possibly enjoy being forced to fork out upwards of 4$US or more per gallon of gas, but, this is digressing so this is where I will stop and end my review).

I bought this light to install on my mountain bike because I ride my bike often and at times I ride in the dark, specially coming from long hiking and bike rides throughout the evening and this thing held up to its potential to different modes the brightness I rode my mountain bike along with my daughter in order for us to see, especially when we’re coming back from the park and it’s dark And the bike trails are not lit, and this thing is amazing the lumens the distance of the light, the intensity of the light with the brightness is just amazing. I could put this in the spotlight motion. I could see farther ahead I could even do it in a strobe like manner And I’m very pleased. I’ll be looking to see if this company has more products for my mountain bike and her this is a very good product and the durability of the light seem very rugged the outer case in a strong my only drawback is they didn’t put one of the foam ring plastic rings, so I can make it more sturdy so I had to design my own, but I got it to work and I’m loving this one of the best lights I’ve had on my bike now I am out here riding even by myself on dog trails with no problem

Edit 06/27/24 - I am now giving the light 5 stars. I used the light a few times on rides since this review and did not get the dimming effect. the light maintained it's initial brightness. I suspect the dimmer is a protection feature when there's overheating.Secondly, I did hear back from support and they confirmed that it's likely the overheating protection feature kicking in.I have upped my rating to 5 stars since the unit operates as intended, is VERY bright and has a secure installation point and easy to aim. The light spread is wide and illuminates a lot of the path ahead. It is also priced affordably!I do not hesitate to recommend this light!Initial Review:Brightness - The most important factor when choosing a light... initially it is very bright and very impressive, but after riding for 3-4 minutes, it dims to less than half-power. Shutting it off and on again restores the light to full brightness once more, however, the it dims again within 30 seconds. Did this on-off process a few times with the same result.Warranty - I did not use the light until day 31 of ownership so I could not return it : ( However, I did send an email to inquire about a possible claim for replacement under warranty. It's been 5 days and no response yet... I just sent a follow up email.I will update this review if the situation improves.

The first day or night I got it worked great. But then 3rd ride the light started dimming. I figured it needed a charge, so I charged it, wouldn’t you know by the 2nd mile started dimming Again. I continue riding by 3 1/2 miles completely shut off. So it’s 430 in morning completely dark out n I have no light!! I continue charging n same thing the only way it doesn’t shut off is if I only use spot light. For that I would have kept using my old light. This morning was the last straw dimmed then went out after charging all night. N the supposed 4 blue lights were all on. According to the small booklet that indicates fully charged. What I think it’s fully charged of. BS. Never will buy this company again. P. S I also did let the rest of my riding group about the lights n company. TY. Have nice day
