Busch & Mueller "Big Bang"---the ultimate bike light?

Wow. Looks very impressive. Ridiculously pricy, though. A grand for a bike light? Still, impressive technology. |

It's good a "bright light" manufacturer has finally discovered optics! However, I don't think a bike headlight has any need to be as bright as a car headlight. Unless, that its, you're descending mountain roads at 55 mph at night. - Frank Krygowski |

I expect those who ride 55 mph down fire roads and through swamps at night will chip in shortly... Pat Email address works as is. Chip. The light looks impressive, almost too bright for a bicycle, and at a kilobuck, way more than I would ever spend on a light. I ride at night when it's decent outside and the meager light from my Cateye is enough for any sane speed on a trail. About 15 MPH is my sanity limit at night unless it is a full moon night where I don't really need the light at all for off road. OK, I'm nuts to ride by moonlight only, but it is nice to be able to ride past the houses with dogs and not have the dogs even know I went by. That light looks like it might ruin my night vision for looking to the side for something out of the beam path. A thousand bucks would sure allow me to trick out my ride, so compare that to just a high rent headlight. Anybody want to guess how much you could spend on the ultimate ride? Start with a thousand dollar light and build a bike around it. Not me. Bill Baka |

Thinking about this on the way home last night; OK, your normal HID light seems to run around $500. Is the precision optics for this really worth another $500? Pat |

I think it's very hard to justify even the minimum price of an HID light, considering the relatively short lifespan of HID bulbs and their high replacement costs. High flux LEDs like the Luxeon K2 and Cree Xlamp XR-E are beginning to offer HID-like intensity at equal or better efficiencies-- along with outstanding robustness, unprecedented longevity, and inexpensive driver electronics. I believe that these LEDs combined with lithium batteries (like those in the latest generation of DeWalt cordless power tools) and built-in smart battery management systems will characterize the next generation of high performance bike lights. As the performance of LEDs rises to the point that 2-4 watts really does produce enough light for a satisfactory headlamp, there may be a resurgence in the use of sidewall generators and dynohubs. Active power management and ultracapacitors for standlight capability would make such generators more useful than ever before. Chalo |

I'm currently using a B&M generator with a B&M 6V/3W headlight and am very pleased with the lighting quality on road or bike path. I've also run the light at 2.4W with little difference in lighting capacity. Since they have a model with a built in LED for standlight purposes, it seems we're already where you think we might go! The only bad thing about the light is its bulb is hard to find with only about a 100 hour lifespan. LEDs could really help in that area. SMH |

DiNotte, makers of very nice 3W and 5W Luxeon lights, have been looking at developing a model for use with a dynohub. I emailed DiNotte about this and they said it was do-able, but that the price for the light would be very high. Mike |

Nevertheless, I for one do like the active power management idea. I think I've posted this regulator idea here before, but what the heck, I'll do it again: http://www.nscl.msu.edu/~daniel/regulator.html The generator charges a rechargable battery, which powers the lights. With such a setup, the regular lights /are/ the standlights, with a much longer duration than the usual little LED standlights that shine for a few tens of seconds. This could be particularly appreciated in foggy conditions where penlight-battery lights don't quite cut the mustard, but generator lights are at least adequate. Of course in really, ~Really~ thick fog, one would want something brighter than 3 watts can illuminate. Or just stay off the road altogether. cheers, Tom -- Nothing is safe from me.
