I have an EL300 on my bars and a Planet Bike Super Spot at the bottom of my left fork. This is adequate for 12 mph night time riding either on totally dark paths or with street lighting. It isnt enough for intermittent street lighting because my eyes dont adjust fast enough to the changing light levels. I dont find much difference between the output of the 2 lights, although the Super Spot may have a slightlyt wider spread of light, so buy according to price.
