What bulb for dynamo.
I have an old cateye dual daylight system (push fit flange bulbs), the
battery has died again, and I am fed up with haveing to charge lights every few days. I often forget. So am strongly thinking of getting a dynamo system. The Shimano NX32 6V 3W Dynohub with Mavic Rim look nice. What bulb(s) do I need. Do I need special dynamo bulbs, or will any 6V3W push fit bulb do. Can I use cateye 2.4 W bulbs?

If you do have any bulbs, best plant them in the ground and watch them grow. Might I suggest you use lamps instead ...... if you put electricity through *lamps*, then they glow. Bulbs *grow*. -- Ian |

So am strongly thinking of getting a dynamo system. The Shimano NX32 6V 3W Dynohub with Mavic Rim look nice. The newer Shimano Ultegra and XT dynohubs aren't much more and are reckoned to be quite an improvement over the Nexus. See http://kinetics.org.uk/html/shimano_hubs.shtml What bulb(s) do I need. Do I need special dynamo bulbs, or will any 6V3W push fit bulb do. Can I use cateye 2.4 W bulbs? If you're not running a tail-light it won't be a huge amount of time before you blow it. It'll work as an emergency spare, maybe for a few months, but it'll blow well within the life of a 3W bulb. I got Roos an Ultegra hub built into a wheel and a B&M Lumotec Oval Senso Plus (with a 3W bulb) for Christmas, and it's done very well. The lamp has a light sensor and just turns itself on as light falls. Sounds gimmicky but works very well, and eliminating the mechanical switch makes it potentially more reliable.

This still won't protect the bulb from overvoltage on descents, as a batterylight won't have the necessary zehner to limit overvoltage. --- Marten Gerritsen INFOapestaartjeM-GINEERINGpuntNL www.m-gineering.nl |

Do I need special dynamo bulbs, or will any 6V3W push fit bulb do. The latter, usually made by Philips or Reflectalite. Wot Zog said. I also got a micro maglite and put it and two spare lamps in the Maglite case, in my tool pack. Needed once, and was glad I had it. Can I use cateye 2.4 W bulbs? Only if you also have a 0.6W taillamp. Er, no, you can use 2.4W with or without tail lamp, but of you have no tail lamp then why not use 3W. Which is prolly what you meant?

And I've blown up a couple of 2.4s in the SON powered Brom setup (first was finding out the hard way that's what happens, 2nd was its replacement which I had handy at the time but then lost the Round Tuit to get a proper 3W replacement before it also went Foom some time later).

Bulbs *grow*. www.dictionary.com gives a number of definitions of "bulb", one of which is "An incandescent lamp or its glass housing". Perhaps you should write to them to let them know they've got it wrong. -- Dave... |
