This Nitecore Blue Filter is an accessory for flashlights that will match a 34 mm bezel diameter lamp. For improved light transmission and heat resistance, the filter lens is made of glass and is coated on both sides. This filter is rendered durable by an impact-resistant rubber frame; it also has an integrated lanyard attachment hole which provides convenient carrying. This filter can also be used to cover the flashlight bezel as the lens can be removed.
