regulated lighting (350 lumens) and a wide and intense beam that will last
for the entire activity. Designed for action, the ULTRA is held securely on
the head. The ULTRA is extremely reliable: in all weather conditions, with
long burn-times, the power level is easily verified. The ULTRA’s accessories
allow the headtorch to adapt to the user’s needs. Most notably, the optional
