Based on the already successful Paralow HS403A Red Dot, Holosun has released a solar powered version, the HS403C. This new product has two power systems, one is operated by solar power only while the other operates on battery only. Out of the box, this red dot is automatically solar powered. The red dot intensity also auto adjusts to ambient light. If there is not enough light, such as at night, the sight will automatically switch to battery power. Now it will operate like a regular red dot such as the HS403A. You can adjust the intensity by pressing "+" or "-" buttons.
The sight will automatically switch back to solar mode after a programmable time of up to 12 hours. The sight is always on.
