The L-915S Infrared Flashlight from Pulsar increases the effectiveness of night vision devices by adding infrared illumination using a 915nm Class 1 eye-safe IR laser. The beam size and intensity level and beam position are adjustable, allowing a user to find the best illumination for any specific situation or object. The intensity level is adjusted by rotating a dial next to the ON button. The beam size can be focused from a narrow spot light to a broad flood by turning the hood at the front of flashlight. Focusing the laser to a narrow beam illuminates a smaller area, but will illuminate to a greater distance. An unfocused, wide flood will not illuminate as far, but will cover a much broader area. To maximize the light's additional illumination, the beam position can be centered in the night vision device's field of view. A green LED indicator turns on when the IR laser is activated, and when the batteries run low, the indicator changes to red.

The flashlight can be mounted on any Weaver Rail system or, using the included adapter, attach onto any night vision optic that has a 1/4"x20 tripod mount socket. This will allow the user to attach the light to increase the effectiveness of night vision riflescopes, binoculars or monoculars without having to hold it separately.
