 
 MYO® XP PETZL
   Powerful headlamp, 4 lighting levels,  Boost mode and Wide Angle lens
   The MYO XP headlamp was developed for high-level  performance. To do this, it uses a high-output LED, a Wide Angle lens,  three constant lighting levels and a flashing mode. This headlamp  provides powerful lighting that can be adapted to the situation and the  activity. The Wide Angle lens option is useful for instantly switching  between long-range and proximity lighting. If necessary, it is possible  to occasionally increase the light output to 150 lumens with the Boost  mode (to locate a person, a car, etc.). To efficiently manage battery  life, this headlamp comes with a battery charge indicator light.
