User Review: Petzl Tikka XP
Price Paid: $40
Really, seriously, don't leave home without it. Good battery life, even in cold conditions. Worked fine when wet.
I like being able to toggle the diffuser, which I use for reading at home or in the tent, or when a wide beam of light is required (ie changing in the tent). The overbeam helps when you want to extend your range and find out exactly what that strange noise was.
A+ product from a quality company and worth every penny.
