Klarus XT21X Pro - 4400 lumens - 21700 x1
The XT21X Pro is an upgrade to an old faithful that has been in use for years. This light uses an included 21700 5000mAh battery for power and is rechargeable, with the option to swap it out for an 18650 (sold separately) if you wish. Klarus's newest tailcap switch makes switching between modes and power control easy even through gloves while the body switch only cycles modes.
