I just relocated to Seattle and know the winters are going to be long and dark. So, I am looking at a light setup for my daily commuter. My budget is about $750 and I need about 600 lumens front and about 150 back. The 600 lumen front should be split between a handlebar mount with wide fill and a helmet mount with a focused beam. I don't want any do it yourself or strapping on a flashlight. Good run time with about 2-3 hours on high would be perfect. Durability in wet environment is a must. What would you put on your bike faced with those criterion?
