Lumen

The Cycle Lumenator draws 10 watts from your battery to deliver a full 1000 lumens of light with a 12 degree beam angle for great forwards and side visibility. It is waterproof, reverse polarity proof, and tolerates up to 100V on the input.  The multi-brightness version uses a handle bar push button and can run with three brightness levels, while the standard model has a single on-off button on the light housing.
