The rule of thumb when night riding is that you can't have too much light and the Light & Motion Seca 2000 Race will give you all the light you'll ever need. The 2000 gets its name from the, unbelievable, 2000 lumens that it throws out. The improved beam pattern, of its proprietary custom reflector delivers a broader spot and clean even fill, for confidence at any speed. Run times vary from one and a half hours on the high setting (2000 lumens), three hours on medium (1100 lumens) to six hours on the low setting (575 lumens.) Rubber strap mount takes the hassle out of mounting your light to the handlebar or helmet. The Seca is the only high performance light on the market with proven waterproof connectors, allowing you to ride on any terrain and in any weather. 343 g.
