The SureFire X300 Ultra Thumbscrew Weapon Light in black is the T-slot clamp version of the best-selling X300 handgun light, rated at 1,000 lumens (SureFire part no. X300U-B). Its TIR lens creates a far-reaching beam with a larger center spot and plenty of spill, which works well for close- to medium-range identification. A thumbscrew clamp attaches it to Universal and Picatinny rails found on most handguns, and ambidextrous switching lets you control it without changing your grip. It weighs 4.1 ounces with its batteries.
