The ND5 Laser Locator light utilizes a proprietary 20MW Green Laser which operates at 532NM using two, 3V lithium batteries. Green is the easiest light or color for the human eye to see and causes no typical “night blindness”
associated with standard or high intensity flash lights. Thus the ND5 provides illumination completely suitable for night work with the least
amount of eye adjustment.

Green light is the most visible to the human eye
(See Chart) and requires the least amount of eye adjustment at night.
An eye that has adapted to daytime conditions generally has a maximum sensitivity around 555nm. Compared
to the color red which optical spectrum is around 630 – 650nm our eye is closer to the Green region of the optical spectrum at 510 - 530nm.
