Baldr S is a compact rail-mount light with a laser light combo. This tactical light boasts an impressive 800 lumens of cool white light for various tactical situations, and a 100-lumen light for indoor use. Baldr S BL tactical lights feature an adjustable blue laser beam for accurate targeting. Brighter than an ordinary red laser beam but not as glaring as the green laser beam in close-range uses. With a built-in 3.7V 380mAh rechargeable lithium battery, the Baldr S guarantee a maximum runtime of 140 minutes, ensuring you’re always prepared. The rechargeable tac light fit seamlessly onto Glock and Picatinny rails, making them serve as Glock lights or Picatinny lights for your firearms. Featuring a patented sliding rail mount that can be custom-fitted to your specific rail length. Ease of use is paramount in tactical situations. The Baldr S tac light operates with dual ambidextrous switches allow for easy momentary-on or constant-on activation with either hand. You can also easily switch between white light, a laser beam, or both without powering off.
