Even on low beam. It's not a low beam. As you could have looked up and mentioned yourself, your L&M flashlight's low setting produces 175 factory lumens. An undamaged Luxos is certainly putting out less than half when you ride at 10 mph, and much of it purposefully directed at the beam's top. Good point, that there's a difference between "low beam" and "dimmer beam." When I mentioned upthread that there might be a (very) few times I'd like a high beam, I meant light shining upward, not light just shining brighter. For decades, cars have had high beams (essentially a conical spray of light) and low beams. The low beams concentrate light just below the horizontal cutoff for "throw" down the road without blinding others. As a side effect, that uses the available light more efficiently. And if the optics are the best, the portion of the beam that shines closest to the vehicle decreases in brightness, to give uniform illumination. It's worth noting that conical beam bike lights (all non-StVZO bike headlights) don't form a correct "low beam" when tipped down. They overcook the pavement right in front of the bike. Your eyes adapt to that hot spot, making them worse for seeing elsewhere. I suspect I've got a problem with my light and will do some more testing tonight with my sooper-sophisticated Radio Shack multimeter. More uncertainty induced by a questionable cat meter, operated by a lawyer. For how many years have you been complaining about that Luxos? Come on, send the damn thing to Frank! The California-made, plastic flashlight he is willing to dump^Wswap has not gotten better by sitting in his garage. Actually, it's in my basement. :-) Based on the Peter White beam shots and the some other stuff off the interweb, the light should be brighter than it is -- unless the interweb is wrong, and that's impossible. Maybe your intraweb skills that are inadequate. Forget PW's sales material, it's a nice presentation of beam shapes, but similarly exaggerating of the brighter lamps' visual impressions as b&m's pictures taken inside their misleadingly lightly painted garage. By contrast, J. Basler's photos and O. Schultz's measurement data have been up for years for the inqusitive to study -- and for the ignorant to ignore or deny. This https://www.baslerbikes.de/files/BaslerBikes/Bilder/Fotos/Leuchtentest%202013/Leuchtentest/IMG_0040_233731.jpg is a better illustration of what a Luxos rider sees on dark asphalt, at 20 kph. As I said, I don't know how we'll agree on beam shots that accurately represent the brightness of a headlight. For one thing, it seems that people's night vision varies quite a bit. I know I see much, much better with my Cyo (or even my Eyc N Plus) than that dark photo shows. For conspicuity - being seen by other road users - I think a useful test is to note how far away one's headlight illuminates a road sign. My Cyo lights up a stop sign nearly 1/4 mile (400 meters) away. That means the light has traveled 800 meters to the sign and back to my eye, despite reflective losses. ISTM that's clearly sufficient conspicuity. For illuminating the road surface, I've proposed that if my headlight beam is visible on the road under a street lamp, it's bright enough. I say that because if I had to ride under street lamps with no headlight, I'd still be able to spot rocks and potholes. But I don't expect to see my headlight beam on a really wet road. The water surface acts like a mirror, bouncing the entire beam down the road, reflecting zero back to me. That's true even of a car's headlights. It does not mean the headlight beam wouldn't show a rock or other obstacle sticking up. And while it's true a pothole filled with water can be dangerously invisible, it can still be invisible, with a car headlight. It will appear even darker if, before steering onto treacherously dark Dyno Flicker Park trails, you had just taken out your low-light vision by your 800 lumens flashlight beam switched on due to competing road traffic's glare. Yes, one's own headlight can ruin night vision if the light's bad enough. Opposing headlight glare can hurt too, as can other light sources. My most common night utility ride takes me from a busy, well-lit highway to a somewhat darker residential street, to my even darker street. Perhaps I'm lucky that the transition is somewhat gradual. -- - Frank Krygowski |

How many here have crashed on the road or a rail-trail because their headlight was insufficient? (I'm not talking about off-road woods riding.) -- - Frank Krygowski |

Perhaps that road was wet. My asphalt is usually grey rather than black, including the tarmac on the lane where this photo was taken: http://thorncyclesforum.co.uk/index....59139#msg59139 I still use the first series Cyo, waiting for a quantum-step from BUMM. But meanwhile I've given up riding in the night when it rains because at my age a broken hip will just be too debilitating. I've got a couple broken ribs from the last crash that hurt like a MF. I crept home in the pouring rain last night, feeling every unseen bump climbing up the goat road to my neighborhood. Creeping along at 6-10mph up a climb, I decided to skip the Luxos dying Tinker Bell mood light and fire up the L&M. Today I drove to see if I could get some healing, so no riding home in the dark tonight. I didn't bother with more testing last night. Maybe I'll do that tonight. You're just putting the rejoining of the bones off, and weakening the bond that forms, by doing handyman jobs on you bike. Sit in an easy chair with your feet up and get your dog to bing your slippers. The deal with dyno lights is that they are wickedly expensive, and with a decent hub dyno, even more so. You would think that $400-500 for tippy top of the line stuff would get you a stadium light with cut-off. You would not even think there would be any back-and-forth on the subject. I've been saying that for a very long time. I see absolutely no reason a bicycle shouldn't have lamps at least as good as those on a car, and I don't mean the crap lamps fitted to American cars, I mean European E55 spec lamps or better. The good news is that my Showers Pass jacket kept me dry. That's a nice piece of kit. And all my wrenching over the weekend produced a quite drive train. The BB30 bearings were in great shape, and reinstalling the crank with a little grease stopped the clicking. The dyno wheel has a different rotor which was a little grabby, but not terrible. I've developed my bike to near-zero maintenance. Once a year I change the gearbox oil, give the clickbox for the gears a shot of Phil, and every second or third year I check the thickness of the brake blocks, the depth of the rubber on the tyres and the wear on the chain which runs for its entire life on the factory lube. Five stars for the over-priced Hayes feeler gauge: https://images-na.ssl-images-amazon....L._SL1500_.jpg Don't you have a thumbnail? Or a torch that you can hold behind the brake block which instantly tells you whether there is the right amount of space and whether the block is angled right if need be or straight if that is wanted. Perfect adjustment of the calipers with no drag. Another Christmas gift was this: https://images-na.ssl-images-amazon....L._SL1000_.jpg Also convenient, but redundant.

And why aren't spokes 1/8" thick? If one breaks, the mountain lions will get me!" A bicycle should be an example of appropriate technology. Yes, "appropriate" varies from person to person. But only bicyclists traveling as fast as cars need car headlights. I don't understand why bicyclists demand overkill in just this one area. I do agree about the cut-off, though.
