PetzlHalogen Bulb 4.5 V

Switching to a halogen bulb will increase the range of your Petzl Zoom or Megabelt headlamp to 100 meters. If you are climbing or backpacking at night the Halogen bulb is the only way to go. Keep a standard bulb handy for basic camp chores but switch to the Halogen anytime you are active.
