Continuing our recent exploration of newish bike lights (see links below), we turn our attention to the Knog Boomer Rechargeable. The Boomer has an integrated lithium-Ion polymer battery, which when you pop the light out of its silicone case can be inserted into the USB (Universal Serial Bus) port of your computer for recharging. Available for front and rear lighting on a bicycle, the Boomer throughs our up to 55 lumens for the front beam and can run for 12 hours on flashing mode.
