You can sometimes catch the Dinotte Pro-series on sale at about a 100 sometimes. But for something AA powered, it's about the best there is.

Also take a look at the Princeton Tec Products. Some of their headlamps come in a Bike version too. Those would also be AA powered. I have a friend that rides long randonees that uses their Corona-Bike. Not enough light for me, but she loves it. I personally use the "EOS-Bike" on my helmet to suppliment my Dinotte.

Another good AA option is the Fenix L2D-Q5. I have one I use at work and it is a good flashlight. Couple that with a two-fish style lockblock and you have a nice bike light. I use it on my bike-friday when I travel and it does work good as a bike light. But I still prefer my Dinotte when at home with my regular bike.

Also check out the Candle Power forums. There are some bike specific threads that you may find of interest.

What constitutes "enough" light is a matter of debate and is a personal preference. No two people seem to ever agree.


Good luck to you
