The light on your smartphone might be bright enough to find a lost contact lens, but what if you need to light up an entire driveway? Or shatter some glass? Or light up a driveway while shattering glass (not as rare a situation as you might think).

In that case, your best bet might be this Army Gear Tactical Flashlight — a military grade device that’s waterproof, made of ultra-lightweight titanium alloy, and can supposedly put out 800 lumens of light.

It even comes with five light modes: full, medium, low, strobe, and SOS. (Meaning the light will blast out the morse code signal for “help.”) It also has a rotatable chassis so you can narrow the beam of light, and the sharp “tactical head” can be used to shatter glass or even fight off an intruder, after you’ve blinded them with those 800 lumens, of course.

Best of all, it comes in a two pack, so you can share one with a buddy or just double-fist your flashlight adventures. This is $59.99 worth of flashlight, available to you now for just $17.99 (that’s 70% off). Even in the dark, you can tell that’s a pretty good deal.
