I thought 2.4W was for front light only setups and 3W for front and rear however I don't think it'll make much of a difference running 2.4W on both as the draw from the rear lights will be minimal.
On the off chance it's 32h Spa Cycles are still doing the SP PV-8 for £50 though...
Thanks for your thoughts. Yeah from chat around this online I can see that people think the modern rear lights have so little power requirement that the noticeable diff in light performance between 3W and 2.4W is negligable, unlike with incandescent lights.
Hoping to hear from someone who’s actually tried one, with F&R LEDs, to offer their anecdotal experience.
Skülly-
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.
