The outer ring of concentrated light on my handlebar mounted 2W Planet Bike might be 20 feet out. My 1/2W Planet Bike is on my helmet and points to just in front of my wheel most usually. I always ride on the MUP because I almost always have it to myself but if I do have somebody coming at me, there just isn't anything realistic they could ask of me of my lights other than what I'm doing.
How you like the Planet Bike 2 watt Blaze? It has been suggested and rightfully so, to get some good lights on my bike if I am out there at night(commuting). Right now, the high-end lights will have to wait. I did order the 2 watt Blaze.. Hopefully it will get me by until I can get something better...
