DarkEnergy, the SOG line of flashlights, pierces the night. They look different and they behave differently. Our goal was simple. We wanted you to have the brightest flashlights of their size. You will be surprised at the power when you switch on the DarkEnergy lights, with 550 lumens in the palm of your hand! Light up the tree tops to appreciate the penetration and range. We also wanted you to have the best switch in the business, so we developed a full on full off switch (each and every time) that also half-taps to 40% output, reading mode, and then tactical strobe. The 6061 T6 aluminum housings are aggressively checkeredÂÃ_..more than any other, and are coated in a Class III anodizing for maximum durability. Count on us when light is not enoughÂÃ_ but when blindingly bright is.
