Hello! What to chose between Petzl Zoom and Petzl Myolite (no LED's) for long distance throw? For short or medium distance I have a Tikka and Tikka XP. So, have somebody tested both headlamp? I intend to use rechargeable cells. Please comment also the beam quality and size of bezel if cares. Weight is not so big problem for me. Until now no experience with incandescent bulbs. Somme difference between halogen and xenon (life, brightness)?
