As with most things you get what you pay for. If you are serious about night riding, get a strong light. This year because of my work schedule I decided to get a headlight for my bike so I could ride into the darkness after work. Based upon a lot of research I bought a 2011 Cygolite MityCross LED headlight. For 2011 Cygolite upped the lumens to 480...an outstanding light...latest technology with LED for low power draw and Lith Ion battery for long life....3 power ranges and lasts a long time on its highest output...I can go a few rides before recharging. They are available on ebay for about $200 and worth it IMHO.
