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.
