Olight Blue Filter for M31, M3X,and SR50 LED Flashlights
The Olight Blue Filter produces a smooth beam of blue light. Hunters often use the blue filter to track wounded game at night because blood stands out more distinctly against foliage when viewed under blue light. The reduced intensity of light output also makes this filter ideal for close range, non-tactical applications such as map reading. Features:
- Fits the Olight M31, M3X, and SR50 LED Flashlights
- Olight Filters and Diffusers outside use a high quality TPU body construction which offers flexibility, durability, chemical and abrasion resistance.
- The lense of the Olight filters are made of ground glass.
- Lenses feature a top quality Anti-Reflective coating on BOTH SIDES for optimum light transmission.
- Offers a lanyard loop for convenience.
