The Double O isn’t exactly something we’d expect 007 or any other British super spy to use, but these are being developed in the U.K. by Paul Coksedge Studios through a Kickstarter campaign. The Double Os put out 80 lumens up front and 45 lumens in the rear. The designers suggest that this round style uses less bright LEDs but more and that results in a more visible light – without being blinding or otherwise distractive to drivers and other cyclists.
These charge up in 90 minutes via USB and have three modes – steady, which can run for about 2.1 hours; flashing at 4.2 hours and Eco at about 10 hours.
