This Blue Filter from Nitecore is a flashlight accessory that will fit a light with a 40mm bezel diameter. The filter lens is made of glass and is coated on both sides for enhanced light transmission and heat tolerance. An impact-resistant rubber frame makes this filter durable; it also has an integrated lanyard attachment hole that offers convenient carrying. Since its lens can be removed, this filter can also be used to protect the flashlight bezel.

Features:

• Flexible filter frame is adaptable to a head diameter range of 40mm
• With the lens removed, the filter may be used as a bezel protector.
