I picked up this AA flashlight from ShiningBeam about 6 weeks ago, and it has worked out very well. I mounted it to my helmet with a couple of strong bands and it provides so much light its unbelievable. I have a Planet Bike 2watt headlight also mounted on the bike, but it doesn't put out anywhere near as much light. The PB cost twice what this flashlight cost also. Wish I had saved myself some money and just purchased 2 flashlights. I use the light with Sanyo Eveloop AA rechargeables and get about 3 hours on high.
