Exposure Sirius Mk2




Charge (claimed/actual): 4hr/5hr

Run time (claimed/actual): 6hr/5.5hr (full); 24hr/18hr (flashing)

Exposure sticks with its tried and tested torch-like design for the Mk2 version of the Sirius and the rubber band clip is quick to attach to any bars. It’s lighter than it looks at 84g and can be used on a helmet. Offering 360 lumens it’s one of the brightest lights we tested, with the new lens giving excellent side visibility and there’s a ‘glare guard’ to protect your eyes. The USB port is well covered from flying front wheel debris too. Our main issue is that the charge time is fairly lengthy, so do it before you go to bed. CJ
