Patrick, My wife and I have experience with several different dynamo LED lights. Edelux, Edelux 2, B&M Cyo, Sinewave Beacon, B&M IQ-X. For us, at this time, the B&M IQ-X is the best for pavement riding. It easily eclipses the Edelux 2. I recall riding with the IQ-X on our tandem last summer on a night ride. It lit up our *entire* vehicle lane. Some folks do not like how there are dimmer spots and brighter spots from the lens. I get it. But we got used to it. On a very dark night it is amazing. Watch for Amazon sales for really good pricing
One really annoying thing (at least to me) is the IQ-X has an automatic feature in which it automatically turns on as a daylight or nightlight, depending upon how much ambient light the device senses. Some might find this an invaluable feature, YMMV. Every time one stops for a bit of time I have to remember to *manually* turn it off, saving those precious watts on those steep climbs (we are currently cyclotouring in SW Colorado). Regarding the Sinewave Beacon: I agree - it could be *the* perfect light if it had an StVZO lens, IMO. I did ask the owner of Sinewave a few years ago if he was going to use such a lens. At that time he said no. Despite that, the Beacon checks off a lot of positive features I wish other LED lights would incorporate. Being able to power an LED light via a dynamo *OR* a USB battery should be standard, IMO. Within the chassis, it also has electronics for a USB output - extremely critical for cnyclotouring. I've had direct experience with the issue of charging a *smartphone* off the USB output: it is a measly trickle charge. But, I think we have to remember that it isn't really the light's fault but rather the dynamo. The dynamo outputs a nominal 3 watts. With losses between the dynamo, wiring and USB device, it really is a trickle. I have had excellent success in directly recharging GPS devices (Wahoo BOLT and ROAM) using the Beacon. Since their batteries are relatively small, the Sinewave Beacon's USB output has recharged those devices within an hour or so of steady riding. Allows one to start the next day with a full charge - perfect for cyclotouring/bikepacking. Good luck, Jeff & Lori Arita Claremont, CA (currently in Silverton, CO) P.S.: We Amtrak'd from Los Angeles to ABQ. Took the Rail Runner (awesome) to Santa Fe. Began pedaling from SF to Durango. We loved the Rail Runner: when the train car's doors were about to close, the audible warning was the Road Runner's "Meep - Meep." ;) On Friday, July 29, 2022 at 8:40:37 AM UTC-6 brok...@gmail.com wrote: > My only dyno headlight experience is with the Sinewave Beacon.
