Ah ok so we’re saying maybe more flicker as you accelerate, or standlight charge happening later. Cool. Thanks. Think I’ll go for the 2.4W. It’s such a bargain, I think I’ll be less stressed about it being locked up outside a school for hours on end.
The 3W vs. 2.4W numbers are what you get from the dynamo from a certain minimum
speed. The all go above that value at higher speeds. People are running 2 headlights from 1
dynamo.
