The running times are: 6hr/laser, 1.2 hr/light, 55min for both laser and flashlight. When the power is lower than 10%, the low power indicator light will be red, indicating that it's time to charge in time now; green light means fully charged.
Two Levels of Brightness & Strobe Mode: Quickly double-click the light switch to switch to different brightness levels (low brightness 200 lumens, high brightness 800 lumens), and long press the light switch to switch to 800 lumens high brightness strobe mode.
Windage & Elevation Adjustment: Elevation(UP/D) adjustment has two adjustment holes, one is blue laser and the other is ir laser.

In order to better protect the pistol laser light combo, please gently tune elevation and windage interactively. Calibrating in one direction with brute force will damage it.
