What's the brightest dynamo light?
I currently use a DiNotte Ultralight, which is a super light. It's bright
and well designed. I would like to try a dynamo hub on my next bike, and I don't know what the hot light setup is. I would not have a problem running two dynamo headlights, as I want the most light I can get. The Shimano dynohub would be my choice. I know the Schmidt SON is awesome, but it's also three hundred bucks, which is three times the Shimano. So, what light(s) shouId I choose to get the most light? Mike |

So, what light(s) shouId I choose to get the most light? Hmm. It may be that your question needs rephrasing. Technically, the amount of light (i.e. lumens) you get will be determined by the generator and the bulb (unless you're considering a generator powered LED lamp). Where that light goes is determined by the lamp's optics. I suppose that's what you're really asking about. In general, the tighter the beam's focus, the brighter the illumination of the roadway. But you don't want one tiny spot of super-bright light. You need a beam of reasonable width and reasonable vertical height. But with a limited light source, you can't spread the beam too far, or you'll be too dim. So perhaps what you want to ask is "which lamp is bright enough and wide enough for my riding application?" One subtle point is that it's good to have the top of the beam bright and the bottom dimmer. This lets you see far enough down the road without having your vision washed out by an extra-bright road surface close to the bike. Anyway, some beam pattern photos are at these two sites: http://www.peterwhitecycles.com/headlights.asp and http://www.fa-technik.adfc.de/Kompon.../vergleich.htm - Frank Krygowski |

I like the Lumotec Oval Senso Plus with my dynohub. But that's not quite the question you asked. If you want the *brightest* dyno-light, you want the Solidlights 1203D: http://www.solidlights.co.uk/products/1203d.php Of course, the price might be a small disincentive. *cough* 145 GBP *cough* plus shipping. Really, I think a good 3W light + a front blinky is probably the best combination IMHO. But, one day... -- Dane Buson - Death before dishonor. But neither before breakfast. |

Mike The SON is $245 at www.peterwhitecycles.com, compared to $90 for the Shimano 3N-71. So things aren't quite as bad as you make them out to be. I bought a Shimano 3N-71 a little over a year ago, and I've been real happy with it. I use it for commuting and I put it on my bike for a 2 week tour in Italy last May. I'm considering setting up my road bike for brevets this summer, though, and the SON would be nice for that. It's sl;ightly more efficient than the Shimano, lighter, and has less rolling resistance than the Shimano when the lights are turned off. mark |

They have a nice rectangular pattern that is brighter at the top, which help a bit with the long range. I have two mounted on the front of my commuter bike - see he http://www.flickr.com/photos/34424013@N00/343394431/ http://www.flickr.com/photos/34424013@N00/343394427/ One is used as a main beam, the other as a high beam by focusing it a bit further down the road. While I take credit for the construction, I shamelessly stole the design from Tim McNamara. Regards, Tom |

I have the newer SON & 2 of the new Shimano generator hubs. (DH-3d71
DH-3n71) SON on a 650 roadie wheel, 1 on a 26" mtb wheel, 1 on a 700c roadie wheel. They put out a simliar amount of power. The shimano is reported to have a little more drag but I can't tell when riding. The total drag is pretty much unnoticiable. Consider the electric 'drag' is 3 watts, plus maybe 1 or 2 more watts for losses. Compare that to the 100+ watts you are putting out a a slow riding speed. Racing watts could approach 500. 3 watts is pretty minor. the headlight light is what matters. I have the Shimano LPR 600? , I don't recommend it. The beam is way too dispersed, it has a second white led that flickers a low speeds within your vield of view and gets brighter as you increase speed. The lense wraps around the top and transmits more light into your field of view. This destroys your night vision. Generator lights need a voltage regulator (Zenor diode) to prevent burning out the bulb at higher speeds. So you can use any light if you add the diode. Generator specific headlights have those diodes built in. the big advantage of a generator is it always works. No dead batteries miles from home. The down side is no light at the stop lights/signs. Add a small white flashing led to the handle bars for in town visability. Rick Tom Schmitz wrote: Gooserider wrote: I currently use a DiNotte Ultralight, which is a super light.

Bought them from Peter White Cyclery. I am very pleased with them. I choose the regular 6 instead of the lower resistance S6 but must say, the resistance is negligible on the inexpensive 6. I highly recommend them. Whatever brand you eventually go for, be sure to get lights that DO NOT GO OUT when you stop pedaling. Not only is the feature nice for stoplights, it's really nice for securing the bikes at night, finding keys and so forth. Bottle generators have come a long way in the last few years. Coupled with good LED lighting technology, they are surprisingly bright. And there's no resistance for day riding. The LED lights, by the way, fully power up at walking speed which is good, if you do a lot of stop and start biking. |

Whatever I have one of each and can't really tell the difference between them as far as drag goes. The Dymotec 6 does appear to be a bit noisier (sort of a whine) than the S6 though. I'm pleased with both. SMH |

I was very surprised when I test rode the bikes. It was really hard to tell the generators was riding the wheels. The Lumotecs are great, though I expected that since Peter White's web pages for lighting products are excellent and he's not shy about offering advice. |
