A great ultralight backup light, the new Ion is small enough to stash just about anywhere, plus the reflector-housed, 1/2 watt LED casts a far-reaching beam for finding your way up that final pitch of or down that last mile back to the car/tent.
Weighing just 30 grams (1oz), the Ion has a pivoting head that angles the light anywhere you need it, and a replaceable 6-volt battery provides power for 15 hours at the low setting and 3 hours on high.
