A powerful bike light with tough aluminium shell suitable for mountain biking and road biking. Boson is small and compact with a Li-ion rechargeable battery and a Micro USB port.

Boson has 5 lighting modes which are cycled through (excuse the pun) with a single illuminated switch. High power pumps out 850 lumens making even the darkest commute a tunnel of light. Turn it down to medium power and you still have 320 lumens to play with - more than enough for negotiating un-lit cycle ways and paths.

If you want to be seen rather than see where you are going switch out to the 6 or 3 Hz flashing modes. Bright enough to be seen even during daylight hours, it really comes into its own during the hours of twilight and dusk.

Note: Boson doesn’t take a "standard" 18650 battery - the battery has both anode and cathode at the same end. Do not switch on Boson during charging as it could damage the battery.
