I used the Moon XPower 300 at muddy hell for my distance light with an old cateye aimed just in front of my front wheel and have no complaints with visibility. On the road the moon has a good strobe at 300 lumens and full beams of 300, 200 and the two lower than that. Stats for power and run time compare to a joystick but the moon only has a bar mount so for helmet use a bit of blu-tac and gaffer tape might be required. Two big advantages though are price (£55 from Parker International) and charging (standard mini USB).
