I got my used P7 from another BF member yesterday. Did not have time to take it for a ride, but I did take it out in the front yard to blind any nocturnal animals or drivers who had the misfortune to be in the area.
All I can say is WOW! The thing made the street signs at the other end of my street glow! I do think I will end up having to make some sort of hood to use on the light when I mount it on my bars. This is the light I bought:

Would like to see what others have done about making hoods/deflectors for their lights.
Can't wait until the next Cub Scout camping trip in May, so I can win the flashlight bragging contest as we sit around the campfire!
