THE BEST ABOUT!!!!!!!
Petzl: Myo 5 - Whether you need a 100-meter halogen headlamp or hands-free, LED practicality for setting up evening camp, Petzl's adjustable Myo 5 is everything you need for climbing, camping, spelunking and adventure racing. It's power and economy in one ergonomic package. Twist the electronic bezel switch for a blast of long-range halogen heat or take it down three notches for energy saving tent tasks. The five-LED configuration provides a range of roughly 15 meters, enough light for walking and general use around the campsite. Choose from three brightness levels to minimize eyestrain while reading maps and paperback novels. The electronic system also monitors battery power and automatically switches to energy-saving reserve power mode when necessary. If you're looking for ways to minimize the weight around your head, check out the removable battery pack on the Myo 5 Belt.
