I just ordered the Mitycross 350. Performance has a sale ending today. I got it for $180 including free shipping.

The Dinotte lights are quite pricey, even with the sale. The flashlights offer a better lumens per dollar ratio, but I really wanted to get something made for a bike. I made my own flashlight handlebar mount using conduit hanger (what I use now for lighting). It works, but the beam pattern is less than ideal and it is hard to adjust the light position. Thanks for the suggestions. New wheels are probably the next upgrade for me (maybe next year?), and I might consider a dynamo hub then.

Thanks again for all the information. I'm excited to have a better light. Depending on the route I take, up to 10 miles of my current commute is on an bike path with little or no lighting. Hopefully it will be easier now for me to see the critters, commuters, and crap on the path.
