Shake Awake™
Shake Awake Technology is a standard feature on all current model Holosun optics and serves to extend battery life by deactivating the optic’s LED while not in use. A highly sensitive motion sensor works to detect motion keeping the LED powered on during use. This allows for duty or concealed carry with seamless operation throughout your day or shift. At the end of your day or shift when your firearm is stored, the motion sensor will detect a motionlessness state and after 10 minutes (default setting) Shake Awake Technology powers the LED off until motion is again detected. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred. The slightest touch of the optic instantly reactivates the LED so your Holosun optic is ready when needed.
Super LED
Super LED technology provides a versatile range of reticle intensity settings from night vision-compatible to daylight bright. Holosun Super LEDs have ultra-efficient power usage creating battery like as high as 50,000 hours on certain models. Our Super Green LED is designed to match the wavelength of light that the human eye is most reactive to.
