Were dynamos, so far, designed to properly match filament bulbs or, conversely, bulbs designed in such a way not to blow when properly matched to a standard 3W dynamo !!
So, why "3" ?
- perhaps dynamo maximum permissible dragging ?
- filament bulb minimum required "lumen" production ?
- what else ?
