Lezyne

The lights themselves are great, nice and bright with different settings/blink patterns to match the conditions! The main problem is the strap for the rear light, it's flimsy and does not have one side permanently fixed to the body of the light. Within a week of buying two light sets, one rear strap broke and the other was lost while off the bike being charged. Lezyne sells replacement straps for ~$5, including different lengths, so I bought multiple.

I keep losing lights that have all kinds of creative attach methods at to the bike. I was looking for a rechargeable, bright USB-C chargee light that. Thats exactly what it is. So the light is attached to the rubber strap and cannot fall off. You need to remove the light with the rubber strap to charge it. Not as nice as having it clip in but really nice that it can't fall off.

Only complaint is that the rubber strap could be a bit longer. My gravel bike has a mountain bike width seat post and the strap is a bit tight on that.

I commute in Seattle a couple days a week year around and bought this 15 months ago with the hope of being able to take the round-about way home when its not raining. However, the battery life even on the 100 lumen economy mode was just over 3 hours instead of the 10 hours advertised when new and now it's down to closer to 2 hours so I need to pack my old headlight as a backup if I want to get in some extra miles. When I do need the full power on unlit gravel trails, it does a great job lighting things up but that kills the battery very quickly. If you don't mind charging often, it's a fine light but don't expect to be out too long after dark.

I live in the the Pacific Northwest and commute to work everyday (rain and occasionally shine). I needed a very bright light, with the ability to offer multiple flash modes. The goal of this light is be CLEARLY SEEN by those who are either propelled by a electric motor or a carbon fueled combustible engine, sealed within a metal and plastic capsule, while being distracted by a digital device and a caffeine product.

The Lezyne Fusion Drive Pro 600+ Front Light works, this is a great option for a front light. It's small, but the 5-bulb 600+ lumen lighting system is bright enough to be seen. The 2-flashing modes, and the main light beam (3-options) work well. This light is built like a tank, and battery life is good. I'm not a fan on how the light attaches to the handle bar, but it's functional and helps keep a low profile :) -- I have this light on my two bikes -- buy from BikeTiresDirect, great prices, great customer service, and fast shipping...
