IPSXP Bike Lights,5000 Lumens & 15+ Hours Bicycle Light Runtime,Power Bank Function,USB Rechargeable,IPX6 Waterproof Super Bright Headlight and Taillight,Multiple Modes

This light was better than I expected. It is very durable. High quality material. Very bright also. Worth the money!

The unique mounting clip for the headlight is made of a very stiff loop of plastic that needs to go around the handlebar and then get inserted into a slot where a special nut will supposedly catch threads molded into the strap. But the plastic is so stiff it is very hard to bend it so that it gets inserted into the slot and impossible to remove it by hand. You have to pry it with a screwdriver. And lest you think that makes it harder to steal, the light slides and clips onto the mount easily, and just as easily can be unclipped and slid out.The headlight is fairly bright but ignore the lumens claims which seem meaningless in a lot of headlight marketing. The headlight beam is even and decreases evenly from the brightest area in the center. Unfortunately, for bicycling on a bike path with other users this relatively wide beam pattern with no sharp cutoff makes this light blinding for oncoming path users. If you were bicycling in a place (like a street or trail with few other users) with no other bicyclists or walkers coming toward you it could be OK.There are too many blinking modes in the headlight and taillight for my taste. You have to click through them all to get to what you want or turn off.The taillight seems bright enough although I didn't check it in daylight in street riding.Both the headlight and taillight have built-in LiOn batteries that are rechargable, although annoyingly, the headlight uses a USB-C connection and the taillight a micro-USB connector. USB-C will be the new universal standard and is easier to use than micro-USB.Headlight has aluminum case that looks sturdy. But the weak point may be the plastic mount. Plastic mounts for other headlight models seem to be the most likely parts to break.When charging the headlight it got warm, which is worrying.Have not used it enough to evaluate light runtime claims or durability of batteries, mounts, and lights.Headlight has a nice feature of a USB port that could allow you to use headlight batteries as an extra battery for a cell phone or other item, with the right cord. I did not try this feature.

Seems to go through the battery pretty quickly. On the heavier side but mounts nicely.

The main light is well-made, with a stamped metal body, and the rear flasher light is in a plastic case which seems also pretty sturdy. The main light has a USB-C charging socket and the back light Micro-USB (why?...probably cost reasons). I'm not using the back light. The main light is bright when fully charged, but then the battery is weak, the various light levels are dimmer—unlike the CatEye AMPP lights I also own, which either operate at full brightness or just don't turn on at all. Not sure which is better in practice. But be aware. I also prefer a plastic body for bike lights as the metal is prone to scratches and dents. But it's pretty cheap so if broken just get another one. In comparison a CatEye AMPP800 is $50+.
