One of the lights on my short list was the DiNotte 5W, it either comes with 4 AA, or you can get the one with Lithium Ion cell. With the batteries you have to remember taking them out then putting them in the charger. With the cell you have to remember to take the charger with you and plug it in each time. If you end up with a non-intelligent charger you can easily destroy the battery cell. During the Summer months I may not need to use my light much except from some occasion unexpected late days. If I have a light that takes AA cells I could carry a set of a Duracells and leave them in a plastic bag so that they don't discharge accidentally. Most rechargable batteries loose their charge over time even when just laying around. Since some of the lights only have 2 to 4 hour battery life on full batteries, I'd hate to be caught off guard without fully charged batteries or cells. With the hub, I just can't forget... I will always have it with me. If I end up on a longer then expected ride I also won't have a problem as I'll be making my own electricity along the way. Don't get me wrong there are some really killer battery powered lights out there. The output from either the DiNotte 500L or Lupine Wilma 4 look stunning at: http://www.gearreview.com/2007_led_lights.php. I was tempted to go for one of them, but descided that making my own power was the way to go for the type of riding I do.

Thanks all for the discussion.

Happy riding,
André
