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.

Hiya fellow hub dynohub freaks.
Want to equip my lad’s trek mtb tourer beast with a cheapish dyno setup, picking up a good front light here (IQ XS), rear mini toplight thing (bargain!), gonna rebuild his Sun Rhyno Lite with as cheap a Shimano as I can bear to give him ... SJS have the non-disc LX model in 32 (tick), silver (tick), but it’s rated 6v 2.4w (rather than the more normal 3W). Any reason why this won’t work? LEDs don’t really need all them Watts anyway, right?
