The Olight Baldr S is one of the most powerful compact light/green beam combos on the market.
The white light output of 800 lumens 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, GL beam, and combo settings easily without turning it off.
The built-in 3.7V 380mAh lithium polymer battery ensures a max runtime of 140 minutes.
