1200 measured lumens. Thats right, 1200 lumens. That puts the Pro 1200s light output in the same arena as some automobile headlights. The Pro 1200 accomplishes this staggering output by incorporating two of the most powerful single source LED emitters available today. Housed in two separate reflectors, one reflector acts as a spot and the other a flood. The resulting beam pattern is a perfect blend of both. The Pro 1200 also benefits from our unique D.I.Y. software. This internet based software gives you the flexibility to design your light outputs and flash modes to fit your riding needs, rather than being bound by inflexible manufacturer specifications.
