We have introduced a new version of Krista. Using the same new updated electronics and our new 8 degree pencil beam optic, Krista now boasts over 3000 lumens (up from 2400) and has the same 8 degree beam spread as Sevina. Even though Krista has 1/2 the light output of the very powerful Erica, Krista can still produce a tight spot light on top of the Erica flood. Think of Krista2 as a baby Sevina. They come with easy to follow installation instructions, harnesses and hardware to mount to various motorcycles. A list of suggested custom mounts is also available for specific motorcycles. Some applications may require an additional bracket. Specifications: 36 watts consumption each (on high). 3.73" diameter. High power. 3000+ lumens each. 17 ounces. Fully dimmable. Includes wiring harness. Custom tooled optics. CNC machined. Made in the U.S.A.
