"My understanding and my brief googling is that almost all bicycle 'dynamos' are AC.An AC producing "dynamo" is a just simpler and more efficient to make use and maintain. At those low wattages it is simple, cheap and…"
"Dabba: "I don't know where you got your button battery info from. I looked for the battery details and couldn't find any."
It is literally in the third line of the specifications in the link YOU provided.:
"So a $4 LED 3000 lumens light and battery doesn't cut the mustard? :-)
Comments like this make me wonder whether you have ever ridden a bicycle at night before.
-a. That isn't 3000 lumens of usable light.
-b Any light that…"
"Before you completely abandon things see whether you can do a simple bulb replacement.
Like Scientia said earlier. Halogens use much more power. Normally about 5 times more than LED.
Now not all bulbs will be available in LED…"
"The conversion isn't that complicated to get a 6V battery involved.
Waterproofing really isnt needed for 6V apart from rusting. But covering exposed connections would be smart it would be a good ideal.
mAh ratings and length of time all…"
"True. The 1% claims I made were based on lights off, higher speeds and on time.
If you have a powerful set of lights and are just riding at a more moderate speed then the percentage of total energy does increase. 10-15% is entirely…"
"I hope I'm not being a pain. But before you take the plunge you should recognize what is an issue and what isn't.
To be honest I think my wheel is even worse than what the videos show esp when the lights are engaged. I'd already sent…"
"I think you are overestimating the drag. A wheel spin test like in the videos linked tells you nothing.
Better to look at the ACTUAL drag:
Does 2.5W really matter to the convenience of a dynamo? Some certainly would answer yes,…"
"I've found the switch mostly pretty easy. Both on bike and in a car. Especially in urban areas.
The dangers are remote areas where you might forget and one way roads where you might forget. The you default to old habits.
"You are right.Though I would hope that the COS starts to move away from the ASAP. As the cycling network grows such compromises on key arterial links should be avoided.
But if you consider the view its either bi-dis or no protected cycling…"
"Well written comments I applaud you for taking the time to provide coherent feedback to COS.
I definitely agree that bidirectional cycleways in the manner which are implemented in Sydney are horrible. You've spelled out many of the key…"
" DG "Apparently too many pedestrians had been hit there so they were asking/telling bike riders to slow down."
If this is the case, what do the cyclists here think is the problem causing crashes? Bob…"
