I purchased this light about three months ago and wanted to spend some time using it before writing my review. Since then, I have ridden close to 900 miles, with most of my training sessions taking place before sunrise. I was searching for a light bright enough to clearly illuminate the road ahead, yet not so intense that it would blind oncoming traffic. I believe the cutoff beam does a great job of this. Most of my rides are on small roads with minimal street lighting.
The light has exceeded my expectations, even during bouts of light rain. On most rides, I use the adaptive mode, which works wonderfully—I hardly notice any dimming as the ride progresses. In adaptive mode, I consistently achieve more than three hours and twenty minutes of runtime, which is impressive, though I’m unsure if this is typical performance.
The light easily brightens one lane of the road, and compared to other cyclist lights I’ve used, the Detour light offers much better coverage and light distribution. I took a picture of a dark road to show the difference between the light being on and off, but, honestly, the photo doesn’t do it justice due to the iPhone’s image processing.
I don’t need to remove the light from its base frequently, but when I do, I don’t find it difficult to remove or install, contrary to what some other reviews mention. Additionally, I haven’t experienced the light getting hot—even after three hours of runtime, the body remains cool enough to touch.
The only negative I’ve encountered occurred last week, when the mount loosened slightly mid-ride and the light began to rotate downward. I didn’t have the correct Allen key to tighten the bolt. Since the mount is plastic, I wonder if its flexibility could cause it to loosen over time, but so far, this has been a minor issue.
Overall, I’m very pleased with the performance of this light and would recommend it to others seeking a reliable cycling light for low-light conditions.
