For its size, the Streamlight ProTac 2L-x packs quite a punch when it comes to getting the job done. The aluminum outer case houses a type II military Spec Light, which offer absolute durability for everyday carry and excellent resistance against abrasions.
Brilliant, blinding light is provided via the C4 LED, which has a life span of roughly 50,000 hours and is completely impervious to shock. Because the power output is regulated, you don’t have to worry about the light growing dim or getting brighter. The consistency is a huge help when a constant, trustworthy light source is necessary.
Three operating modes mean you’ll have what you need, when you need it. In high mode, you’ll get a super bright light featuring 500 lumens with a running time of between 2.75 to 3.25 hours. Low mode offers the longest life span with a brightness of 40 lumens and a 30-hour run time. Finally, the strobe mode can be used for both signaling as well as disorienting a would-be attacker, and offers between 3.25 and 4.5 hours of run time.
For the longest lifespan possible, this flashlight is constructed of anodized aluminum, offers water resistance up to two meters, has glass lenses and all openings are sealed with o-rings.
