Every time I looked in the mirror I thought that there was a car behind me. This is because she still had her 1300 lumen 4C light on her handlebars as well, even though I told her to leave it at home. The two lights looked about equally bright (The Lezyne light was measured my a reviewer at 1390 lumens, there is no independent measurement of the Duracell light, but they probably don't lie as much as some of the lights coming in from China). This is really an incredible light for the price (now about $92). There are very few lights with this level of output, that don't have fake lumen claims, and that are all-in-one (no separate battery pack), that are not plastic, and that are less than $100. We were off of the unlit MUP before it got completely dark, but I have no doubt that it would been sufficient. I think that I have finally convinced my wife to give up her 4C 1300 lumen light. C cells were getting to be more than our electric bill. On the negative side, the Lezyne light doesn't come on and off as easily as the 4C 1300 lumen light with my custom mount, and it does not have an adjustable spot/flood beam. The mount is also not able to be adjusted for slightly curved handlebars, like the custom mounts I have made for C and AA diameter flashlights. https://www.probikekit.com/cycling-a.../11170762.html 10% discount for first order. https://www.youtube.com/watch?v=oBVnyCbVL4g I get that kind of light from MagicShine clones for around $20 each, one on the road bike and one on the MTB. However, I spread the beam horizontally with diffusor disks by simply swapping lenses, something that would be difficult to do on this Lezyne light. The big issue with such integrated lights is battery runtime. 2h on high mode isn't adequate for many riders such as myself. It would mean no more light for the 2nd half of the ride. So I have larger central batteries, one is 4x 18650 Li-Ion and the other is 8x. Nice thing is, then rear lights can be tied in a well. The other question is battery exhaustion. Unless it's standard 18650 cells they'll probably make you pay beaucoup bucks for new batteries, hoping you can still get them 5-10 years later. Oh, regarding plastic, these MagicShine clones are sturdy aluminum. My MTB had a hard unplanned upside-down landing where the front light smacked onto the ground with the bike on top of it. Other than scratches, nada, it was still lit there in the dirt. I was more banged up than the light. I don't get the need for a 1,000 real-lumen light on MUPs and roads. I have to deal with other cyclists who use those kinds of lights on MUPs/cycletracks, and they're blinding -- and not in just some whiny way. I can't see where I'm f****** going because someone has a search light in my face. I yell at these people, although I want to stop and beat them to the ground. I don't care what people use on single-track -- assuming it's not a busy single-track -- but on roads, 1300 lumens with the typical spew (can't say what the Barry Beams is like) is rude. The only thing worse are the people with high-lumen flashers. The mistake that most cyclists and manufacturers make is to use a pointy beam. The beam needs to be broadened horizontally just like car headlights do that. Unfortunately there are only two ways to accomplish this. 1. Buy a StVZO light. Very expensive, weak in light output, much too harsh bright-dark border vertically. 2. Buy a sturdy 1000+ lumen light and an after-market diffusor lens. The latter costs five bucks and works great. I chose solution #2. Another odd problem with high lumen lights is that they are easily confused with somewhat more distant car lights. That's just the purpose :-) What? To have the guy at the intersection think you're a car a block away an pull out in front of you? I've been blinded a few times recently with some cyclist coming at me on a dark bike path with lights like that. Just as rude as the idiots in cars with their high beams on quiet neighborhood streets. snip |

I can also ride in the middle of a 2 lane road and see past the edge of the road on both sides. -- JS |

That's just the purpose :-) What? To have the guy at the intersection think you're a car a block away an pull out in front of you? No, the opposite happens. They stop when I am still far away, thinking I would be there in just a few seconds. I've been blinded a few times recently with some cyclist coming at me on a dark bike path with lights like that. Just as rude as the idiots in cars with their high beams on quiet neighborhood streets. As I said, I made sure my lights do not blind. It is rather simple. You set the bicycle into a lane of a long wide driveway or a quiet residential street. Then a car 50ft or so behind that. Both with the lights turned on. Now you pedal or drive in the oncoming direction. Then again from the other direction to watch the rear lights. I want the "light vision experience" to be about the same. No less and no more. Ok, my rear lights are a little brighter than on motor vehicles but not by much. Not as much as a brake light. I found that I am noticed much earlier this way, the "Sorry, I didn't see you" situations are greatly diminished and motorists give me more clearance when passing. Objectives accomplished, I'd say. -- Regards, Joerg http://www.analogconsultants.com/ |

The only thing worse are the people with high-lumen flashers. In the PRP (People's Republic of Portland) you may have thousands of those cyclists. In Silicon Valley only a couple of the MUPs have that issue. Another odd problem with high lumen lights is that they are easily confused with somewhat more distant car lights. It's hard to explain, but in places, it actually makes the bike less visible to on-coming cyclists and cars. I am convinced that the best light for urban riding is a shaped-beam (not necessarily StVZO) 700-800 lumen for seeing the road and a low-watt flasher -- maybe one watt LED that pulses or has a reasonable, non-seizure inducing flash. You may be convinced of that, but where is your double-blind study to prove it? -- Jay Beattie. |

Just as rude as the idiots in cars with their high beams on quiet neighborhood streets. snip I'd like to shoot the SOBs who have super bright likes at night whether on a rail-trail, MUP, dark country road or whatever; when that light completely blinds you and you have to slam on your brakes lest you ride off the path, road or trail and down a few hundred feet embankment or to avoid whatever other hazard(s) might be there. Again, you have to do that becausethe light has completely blinded you. I've had that happen a number of times when I've come around a corner or something and the approaching bicyclist has a light that's probably visible from Pluto. The only thing worse are the idiots with super bright strobing lights at night where it's really dark and there's very little light pollution from other sources. Those sort of bicyclists should be charged with being a hazard to all other road users. Cheers |
