Emitting maximum 820 lumens and reaches as far as 400 yards, Olight M20SX Javelot is a focused variable-output LED flashlight. You can easily access different brightness levels through a side switch, which also double duty as a quick strobe access when you hold it down over a second. The side switch locates next to the end cap switch so that you can access all function easily with a single hand operation, enabling tactical maneuvers in the most challenging situation. The companion diffuser also allows you to turn the focused throw light into an even flood light that allows you see surrounding environment clearly.
