Hand-built in Sussex, the Sirius Mk11 is Exposure’s premium be-seen front light, now pushing up to 1300 lumens from a sealed CNC-aluminium body with no trailing cables or external packs. A 240-degree lens throws light to the front and sides for junction safety, while the DayBright pulse pattern keeps you visible from over a kilometre away in daylight. The OMS button gives an instant readout of remaining runtime.

  • 240-degree front and side illumination
  • Up to 130 hours in pulse mode, 24 hours constant
  • USB-C charging on a fully sealed unit
  • Lightweight 90 g machined housing, made in the UK
