Review on SureFire G2X Series LED Flashlights With Durable Nitrolon Body by Adam Jauregui

This flashlight is light, durable, and extraordinarily bright. It is important to understand that this is a tactical flashlight, NOT an every day carry flashlight. It achieves its brightness by hitting the two 123A cells for all that they are worth. It's like having a car with 2 speeds: 0 and 120mph. The upshot of this is that you only get 90 min on one set of batteries. At $2 a piece, it would get very costly to use this flashlight for your 45 min dog walk each night. You'd literally be replacing the batteries every other day. A more practical everyday carry flashlight will have multiple settings that allow for dimer light but greater battery life (see Olight or Streamlight for good examples). However, if you are in the market for a seriously durable and bright tactical flashlight, this is an excellent choice.
