These are very expensive lights. The Fenix and Zebra lights are available at about 1/5th the price and have similar performance features including battery life, brightness levels and have the option to use rechargable CR123/18650 batteries. (You do need to get the batteries and charger separately which brings the price differential closer to 1/3rd.)
The Fenix P3D or Zebra H60 accompany me whenever I need a really bright light (up to 215 lumen) and work for backpacking and biking. The P1D has similar brightness but lower weight and lasts less long.
They don't come stock with bicycle options but the Zebra lights come as headlamps. Headlamp and bicycle options can be easily rigged with as simple an apparatus as a rubber band over the front and back of the light and over the handlebar or some easy elastic sewing.
These lights are amazingly bright at their highest settings. I've been able to hang a bear rope 50' in the air in the dark using one.
