After a couple weeks of riding, I’m very happy with my two new Niterider Lumina 1200s. Usually run on the medium setting, and then high toward the end of my commute where more light is needed. Never bother with the boost setting, but good to know it’s there if needed. Probably will use on the boost setting on a dark, rainy night, when there is never enough light. They blow away the 700s they are replacing. The pattern is wider and much brighter overall. Every time I get new lights, I always think this is the brightest I’ll ever need, but it never is.
