The M21X Warrior XM-L2 Edition (M21X-L2 for short) is an upgraded version of the original M21X and M21 before it. The M21X L2 uses the latest CREE XM-L2 LED for up to 750 lumens on max output. The durable design comes together with Olight’s various tactical accessories (weapon mount, filters, remote pressure switch, and more) to make an excellent tactical or general use light.
