What are the brightest basic bicycle head lights?
If you re looking for a bright basic commuter light, the brightest are going to be the full watt LED lights like the CatEye HL-EL530, the NiteRider Ultrafazer Max, the Planet Bike Blaze 1 Watt or the Serfas SL-ONE. If you need something brighter than these, you will need to look at the some of the full light systems as the power requirements for brighter lights require more than disposable batteries can provide.
