Fenix AD401 Diffuser Lens – Instantly Transform Your Flashlight into a Flood Light
The Fenix AD401 Diffuser Lens is a practical flashlight accessory designed to convert the focused beam of your Fenix flashlight into a wide, evenly distributed flood light. Ideal for camping, emergency situations, reading, tent illumination, maintenance work, and general outdoor activities, the AD401 enhances the versatility of your flashlight by providing broad area lighting when needed.
Designed to fit flashlights with a head diameter between 20mm and 21.5mm, the AD401 features a secure clip-on mounting system for quick installation and reliable attachment. Its innovative hinged diffuser design allows users to instantly switch between a focused beam and a wide flood light without removing the accessory, providing maximum convenience in the field.
The diffuser evenly disperses the flashlight’s output, creating soft, uniform illumination over a larger area while reducing harsh hotspots. This makes it particularly useful for close-range tasks, campsite lighting, vehicle repairs, power outages, and other situations where broad illumination is preferred over a concentrated beam.
Compact, lightweight, and easy to use, the Fenix AD401 Diffuser Lens is an essential accessory for anyone looking to maximize the functionality of their compatible Fenix flashlight.
