Updated for 2014, the Sirius MK2’s output remains rated at 360 lumens, while the lens has been redesigned to give better side visibility and includes a hood to avoid rider glare.
The price has also dropped.
Because the Sirius is tasked with being Exposure’s road commute light, everything is kept as simple as possible.
Attachment is via a rubberised bracket, and there is just one button with four settings that give run times of two, four or six hours, plus a pulsing option.
A simple, elegant and efficient design that's quick to fit, easy to charge and plenty powerful ?- what's not to like?
