BEST LOW VISIBILITY LIGHT
A favorite of divers around the world for many years
UK's innovative optics system now concentrates 89% of the total lumens of the light into the center of the beam, reducing backscatter and greatly improving beam brightness. Typical lights only focus about 40% of their lumens in the center beam, meaning much of the lumen output is lost as stray light.
