9000 Lumens Bike Lights Front and Back for Night Riding, 5200 mAh USB Rechargeable 6 LED Bicycle Light, 5 5 Modes Bike Headlight and Tail Light Set Runtime 30 Hrs, IPX5 Waterproof, Power Bank Feature

I was twice surprised by this light. My expectations were initially low but almost immediately I realized this light was a solid build with thoughtful details.PackagingThis isn’t going to win any awards, but I appreciated that they simulated a quality package design reminiscent of iconic products like the iPhone and other brands such as Anker. It wasn’t flimsy, and just enough quality and sturdy enough for you to pay attention, rather than dismiss it on first impressions, without being a waste of money. Great.BuildI expected more plastic. Don’t get me wrong, most of it is plastic but it feels solid, and nothing flexes or rattles. The front portion of the main light is metal construction and while I would have preferred everything to be one piece, at this price I was sufficiently satisfied. The join between the plastic and metal feels solid and water tight and while I am generally concerned about waterproofing at joins, I’m pretty confident this will hold. Fitting could be smoother (they’re not as well aligned as they could be), but no concerns about the seal. The buttons also feel pretty solid with firm feedback and crisp clicks. Impressed again.You can see the size of the light compared to my hand.Light / brightnessHere was surprise #1. I had the main light pointed away from my face, but was looking at the light. It didn’t occur to me that it would be set on the highest be default (of course, why would it not be). Even though it was pointed away, it was bright enough that the modestly diffusing lens threw enough light in my direction to blind me. Put simply, holy cow this thing is bright! I’m typically skeptical of manufacturer claims about brightness. At 800lm sometimes manufacturers fudge numbers a little. I have a few calibrated 1000lm flashlights and can say these are quite bright at a similar order of magnitude.There are 3 levels of brightness which you can see from the photos and the levels of brightness are quite distinct. Many times these levels from other manufacturers are indistinct and not meaningful but here, they are and very noticeable which is appreciated and will be useful for a wider set of use cases. On the highest brightness, the lights is visible even with the room lights on.Additionally there are strobe/flashing settings which helps for visibility.MountsThese are pretty basic and functional. I do wish there was a hard mount and locking option, however the lights both clip into their respective mounts (1 for the front mount, 2 for the rear). The main light is physically clipped in with a release. The slide is solid, very high tolerance with no play which was impressive. The release is solid but soft so very easy to use. If the release fails, I’m confident that the slide is tight enough to retain the light.Again, while there is no lock for the light, the mount can stay in place and the light can be easily be removed and be taken with you for when your bike or scooter needs to stay locked outside.For the rear light, the mount is less secure and more like a tensioned pen clip and a thick rubber piece. I wasn’t terrible impressed here but also not significantly disappointed. It does make it easier to remove, maybe less secure (sightly worried about it bouncing loose). The nice thing though is that the pen clip style mount does let you clip it to things like your clothing. Especially useful if you prefer to clip it to your helmet or collar for added visibility.Either way, sufficient for visibility especially not needing to be directional, which brings me to surprise #2: details.The mount is ratcheted so you can change the direction of the throw for the main light. I didn’t realize this at first because the mount is so solid I thought it was a one piece. After turning it over a few times I noticed these dimples and sure enough, a solid click and mount settled into a new offset position. This is great because I’ll actually be mounting it vertically on the stem of my escooter which has limited handlebar space.That being said, the stem where the lights are going to be mounted are much fatter than the typical handlebar. The mounts are all curved on the underside moulded to hug a standard handlebar but too small a radius for my stem.Two other observations — Closure, I’m less confident about the style they use for the straps though I think they should be fine. You just have to stretch the strap to get a secure enough fit.- Rubber, the material feels very strong, sufficiently rubbery, and tacky to hold its place. The underside of the main light mount has an especially tacky pad to aid with grip and holding it’s position which I think is useful, and hides the tension screw of the ratchet mechanism in case it comes loose.Overall, great product, surprisingly good quality and definitely happy with this purchase.
