LaserMax Rail Mount Green Laser Sight for Firearms with Picatinny or Weaver Style Rails at Least 1.75" Long

• What's the big deal about green lasers? Why is the US military converting to green lasers? How does the Uni-Green help my shooting? And how do those wizards at LaserMax do it, anyway?
• Green and the Human Eye
• Stars in the night sky might appear white, but actually they emit a lot of colors. Hot stars emit more blue light, and cooler stars emit more red. Our sun is medium temperature for a star. The sun emits more green than any other color.
• In bright light, our eyes are capable of seeing rainbow colors from violet to red, with peak visibility in the green. In other words, our eyes are most sensitive to the color that is most available from sunlight: green.
• Color Sensitivity and Ambient Light
• Our eyes are roughly four times more sensitive to green than to red under bright lighting conditions. When we're dark adapted the effect is even more pronounced.
• Our eyes adapt rapidly to changing light conditions and most of the time we don't even notice. Typical indoor lighting is actually very dim compared to a bright sunny day outdoors. Since our eyes are less sensitive to light when it is bright and more sensitive when the ambient is dim, the same laser will look dim in sunlight and bright indoors or dusk-to-dawn.
• The shooter needs a color that works best in both bright light and dim light. This is the advantage of green. We can see it farther away (longer range) and under a wider variety of lighting conditions than we can with red. The advantagein an on-the-move shooting situation could make the critical difference in urbancombat, whether for military or law enforcement applications.
• LaserMax goes another step further in providing a laser beam that is quickly acquired by the eye: the beam pulsates. Why? Our eyes are much more sensitive to flashing light than continuous or steady-on light. This fact has been well known for decades. It is the reason that emergency vehicles have flashers. The pulsating LaserMax beam means that a shooter can track muzzle position in his or her peripheral vision while scanning for multiple assailants. The pulsating also indicates that this green laser beam means business.
