Lezyne Super Drive. $100 & you'll get a 450 lumen light with a great flashing mode. The battery is replaceable & could be charged through USB (i.e. you do not need a charger). The body is solid aluminum that comes in three colors. PB 2W is not bad but I would not pay $50 again for a cheap chunk of plastic. Although its flashing mode is good, the light is too weak for city riding at night at more than 10 mph....
