As we've mentioned a time or two already, having a sturdy flashlight as part of your EDC gear is just good plain sense. While your defensive firearm is a highly-specialized part of your kit, a good light has a multitude of uses, both defensively and non-defensively.
The TerraLux Pro-2 is a bare-bones, no-frills tactical light. It has two settings: "On" and "Off." This is a good thing. It runs on 2 AA batteries, offers 3.6 hours of run time and puts out 225 lumens. It has a maximum beam distance of more than 100 yards, is fabricated from CNC machined 6061 aluminum and ships with a lanyard and pocket clip.
No-frills is a good thing when talking about a piece of defensive gear. There's no fumbling through complicated settings; there is "On" and there is "Off." Period. Full stop. The light is solid, well-constructed and, if every other bit of gear we've received from TerraLux is any indication, should last quite a long time.
