DarkEnergy, the SOG line of flashlights, pierces the night. They look different and they behave differently. The goal was simple. SOG wanted to create the brightest flashlights of their size. You will be surprised at the power when you switch on the DarkEnergy lights. Light up the tree tops to appreciate the penetration and the range. They also wanted you to have the best switch in the business, so they developed a full on full off switch (each and every time) that also half-taps to 40% output and then tactical strobe. The 6061 aluminum housings are aggressively checkered. . .more than any other, and are coated in a Class III anodizing for maximum durability. Count on the DarkEnergy when light is not enough. . .but when blindingly bright is.
