First Kudos to Bikesmith's. I recently discovered them while searching for some new tires. They came through when most sites had backlogs. Then within a few days, I also ordered a new 1100 lumen CygoLite to replace my current bike light. Both orders arrived very quickly; in time for my next ride. I tried it out on a 3300 foot long Rail to Trail tunnel that dog-legged at the end - If you start at the one end there's no residual light from the opposing end until the last few hundred feet. I couldn't be more impressed with the CygoLite. I didn't even have to use the full lumen burst mode since it was bright enough with the regular brightness setting. WIth my old light, I could only see the trail reflectors. With this light I could see the sides, overhead, and trail perfectly. The selling point though it is made in the U.S. A great buy at a reasonable price! Well worth it.
