Waterproof Headlamps for Fishing, Hiking and Wet Weather

IPX4 indicates protection against splashing water, not submersion. Petzl describes ACTIK CORE as weather resistant; follow the maker's limits for exposure and care.

Choose a rating that matches rain, spray or accidental immersion risk, then consider red light, beam control and whether you can operate the controls with wet hands. Do not treat an IPX4 rating as permission to submerge a lamp.

Check the exact product rating and instructions. A splash-resistant rating may cover ordinary wet-weather use, while prolonged exposure can exceed the stated conditions.

Read the full IP code and manufacturer explanation. The first character concerns solids or may be marked X; the second describes water protection, and different ratings cover different test conditions.
