TerraLUX Tactical Green Flashlight Filter fits the very popular TerraLUX TT-5 and TerraLUX TDR-2 flashlights. The green light is most easily picked up by the eye and is ideal for forested areas. Ideal for hunters to track game without giving away your presence. Green light also does not attract insects the same way white or yellow light does. Be prepared with TerraLUX tactical filters to fit your specific needs or any situation that might arise.
