Here's a look at the Klarus XT21X...a POWERFUL 4000 lumen light that is definitely best used outdoors.

FlashlightZ sent this down for review and I'm super impressed with it. The long run-times are a definite plus and it's got style. Be careful with this one...it will burn your retinas in turbo mode. 4000 lumens is a very bright mode that should only be used in certain situations.
