I just took a look. I didn't know they made a 900 lumen light. Sure it's $650, but that's a serious lamp for 24 hour singletrack racers. If you were in the back of the pack with one of those the two guys ahead of you could turn their's off . Very slick looking commuter lights from them as well. Some of the best looking designs I've ever seen. Although it's not as if anyone will see them at night. Aside, of course, from the piercing light they produce.
