As one of the most reputable companies on the flashlight market, Fenix is well known for its large selection of lights that are favorites of flashlight users worldwide. The E15 from Fenix should be no surprise as to the reliability and performance of an EDC light, as this single cell CR123 pocket light can produce 140 lumens from its XP-E LED. What really makes the light stand out from its competitors is its runtime: a staggering run time of almost two hours (1 hour 51 minutes), which means less time changing batteries and more time using. The light comes with a market standard IPX-8 waterproofing and is operated by twisting the head.
