Long distance cycling use
I have been using Bookman lights for 2 years in long distance cycling. They are very reliable, great to be able to graduate the luminosity, long duration and reliable in any weather conditions. I use several adaptors to get them on different bikes and interchange batteries when not able to get electricty. Highly recommendable

Batteria di ricambio
Ottimo prodotto, nonostante le dimensioni ridotte queste batterie hanno una durata incredibile. Sono un appassionato di Ultracycling, con 2 batterie puoi passare 2 notte senza preoccuparti della luce per pedalare. Sarebbe ottimo se Bookman producesse un carica-batterie singolo compatibile con power-bank.
Consigliatissimo.
