Fenix AD301-R Red Filter Adapter for Torch Flashlight (21.5mm)

Practical and clear red light.

The Fenix AD301-R Red Filter Adapter attaches to Fenix flashlights to give off red light. It is compatible with most L and P Series Fenix flashlights (except LD01, LD25, LD40, PD31). The red light works great for emergency and relief signals, as it easily penetrates fog and smoke.

The resulting smooth red beam is not visible to the human eye at far distances, won't interfere with night vision equipment, preserves natural shadows in the dark, and won't degrade night vision. It is also ideal for close-quarters reading as it provides great contrast, and is popularly used by hunters during pre-dawn hours to prevent from startling deer as their vision in the red color spectrum is very poor.
