This flashlight diffuser transforms your flashlight into a versatile colored light source. Simply insert a small plastic sheet of your desired color into the diffuser, and your flashlight beam will be filtered to match.

This download includes two versions:

OLIGHT i3T EOS diffuser – specifically designed to fit the popular Olight i3T EOS model.

Standard AAA diffuser – fits many generic AAA flashlights with ~15 mm head diameter.

Great for night use, camping, hiking, photography, or ambient lighting.

Simply cut a 15 mm circle of colored plastic sheet (any color of your choice, e.g. red for night vision) and glue it inside the diffuser. Insert it onto your flashlight tip and enjoy instant colored lighting!
