The Baldr S is one of the most powerful compact light/green beam combos on the market. Its white light output goes up to an amazing 800 lumens and is complemented by a low 100-lumen setting. Its adjustable green beam provides foolproof accuracy when zeroed to your setup. Using the setting switch, you can change between the white light, green beam, and combined settings easily without turning it off. The built-in lithium polymer battery is increased to 3.7V 380mAh, ensuring a max runtime of 140 minutes. The Baldr S still features the patented sliding rail mount to easily adjust the light to your desired position and includes two types of rail adapters to fit both Glock and Picatinny rails. With the quick-install system, you can attach and release the light in seconds for instant activation. This powerful, precise, compact, and adjustable WML is the perfect compact defense light source.
