At SurvivalCache we are always looking for the latest Survival Gear to review and possibly add to our Bug Out Bag, EDC, Emergency Home Kit, or Emergency Car Kit.  We recently came across the SureFire LX2 Flashlight and let’s just say that we were impressed.  


From the SureFire website:
“The LX2 is a compact dual-output flashlight featuring a virtually indestructible power-regulated LED emitter, a Total Internal Reflection (TIR) lens, and a smooth fluted body design that takes it easy on clothing. The LX2’s tactically-correct two-stage pushbutton tailcap switch lets you instantly select output level: press for a momentary-on 15-lumen long-runtime low beam suitable for general night use or close work; press further for a momentary-on 200-lumen high beam—ten times the light of a big two-D-cell flashlight; twist for constant-on low beam, twist further for constant-on high beam.”


There are a number of different accessories for the LX2 ranging from IR filters to specialized pouches and an awesome lanyard system. The lanyard system is included with the LX2 so I can put in a couple of words about its performance.

The lanyard is made up of a piece of OD Green paracord and is equipped with two cord locks and a cord fastener. In a situation where you would be doing a lot of running or crawling where both of your hands would be needed for weapon retention or navigation the flashlight can be worn necklace style around your neck or the cord locks can be adjusted quickly and easily.

Field Performance


I have been pocket carrying this light for a little more than two weeks now, and it has excelled at every task that I have put it to. The LX2 is designed for both utility and as a weapons grade self defense light.

The two stage  push button tail cap works amazingly well. I used the LX2 extensively in a simulated CQB scenario where it performed amazingly well. On the 15 lumen setting it was still out shining the light of my teammates.

When the LX2 was activated on high output it was able to clearly ID target over 125 meters away. The LX2 excels in low level lighting conditions, it was able to temporarily distort the vision of an opponent at ranges of 25 to 30 feet. This light is too powerful to test at close ranges for fear of permanently damaging the vision of the assisting opponent.

Tested against the headlight of the family car the LX2 came out ahead. Surefire has a reputation for making rugged lights. I did not want to torture test the LX2, but it did survive an accidental fall onto concrete from the top of an 8 foot ladder, and it also survived an accidental trip through the washer and the dryer.

The bezel is differentially hardened, and shaped for impact from both accidental dropping onto hard surfaces, and with impact with an attacker. If you are so inclined, the LX2 makes an excellent improvised kubotan, ju-jo,  koppo or whatever other other style of fist load you favor.



I love the way the LX2 rides in the pocket. It is, by far, the best light I have ever owned or used. It runs for a long time on a single set of 123 Lithium batteries, far outlasting any other flashlight I have ever owned.


The one thing that could be seen as a problem on the LX2 is its price. The LX2 retails for around $200 dollars. Also the LX2 runs on special 123 Lithium batteries which are not readily available and are more expensive than a normal battery.

LX2 Pros and Cons




Is the LX2 waterproof?

A: Since the light survived the unexpected test of being run through the washing machine, its fair to say that the LX2 is pretty water resistant. You shouldn’t have any problem using it in the rain or even after accidently dropping it in a puddle. To be on the safe side, avoid fully submerging it in water for any length of time.

Is the LX2 rechargeable?

A: No, it runs off of  special 123 lithium batteries.



After putting this flashlight through all of the tests for brightness, run-time, short falls off an 8 foot ladder, self defense, and the old “I forgot my new SureFire LX2 flashlight was in the pants that I just washed” test…I would definitely recommend the SureFire LX2 for your EDC or Bug Out Bag.  This one was built with TEOTWAWKI in mind.
