Cateye have built a huge reputation on quality and performance, and the AMPP800 is no exception.
A robust aluminium case houses a large capacity li-ion battery with fast-recharging circuit making it ideal for regular commuting. The Opti-Cube technology ensures a smooth and even beam distribution and 5 different lighting modes ensures you can have brightness for dark country lanes or a setting suitable for daytime riding. 800 lumens is a great amount of brightness without taking more power to run down the battery, and lights up enough for areas without street lighting. A battery indicator helps ensure you won't run out when least expected.
