Phenomenal light - Fenix BT20 Bicycle Light - 750 Lumens, 4x CR123

I purchased this light before the option for a rechargeable unit was available. I ran through about 4 sets of batteries (4xcr123), before i purchased rechargeable replacement cells. the light itself is great, having ample light and a very useful beam pattern. I run this light on my helmet, while mountain biking at night, along with 2 lights on my bars. the combination is great, and I always feel confident in knowing wherever i turn my head, there will be enough light.
