Developed specifically for long distance lighting, the O2 Beam was engineered to outperform the best of the best. The rechargeable O2 Beam uses patented O2 Technology to achieve a beam of green light so impressive - you'll have to see it to believe. Green light is best for low light conditions, because the human eye recognizes the color green faster than other colors. Also perfect for hunting, as some game cannot see green light.
