Just to add my two cents. Live in Monterey where L&M is based, and I have some friends who work there. These guys do things like night-time mountain bike rides. They build their lights to work in settings like that. They want a light that keeps them from running into trees at 20 mph, and one that will hold together if they accidentally do hit something. They make serious products for serious cyclists. I have their commuter light, a relative steal at $120, and I'm very happy with it, although I wouldn't mind a longer-lasting battery. If you want a bright, dependable bike light (and if you use your bike as a vehicle at night, you should), take a look at the L&M offerings.
