Used to preserve the eye's natural adjusted night vision. Will disturb eyes the least of all colours which helps your eyes to stay adjusted for night conditions when map reading or navigating, use by aircraft personnel, military and hunters to avoid spooking game including deer as they see very poorly in the red colour spectrum.
Used with night vision equipment, produces less disturbing light. Good for navigation or map reading as it shows contour lines better than red. Green is also used for hunting as it will not alert game and it's the brightest of all the colours for easier navigation and also makes it easier for others to see you.
Useful for map reading, hunting to avoid spooking game and tactical applications. Blue provides a little more light for easier viewing or navigation over red filters.
Sizes available to fit all Olight flashlights.
