The DarkEnergy 247A pierces the night with 247 lumens in the palm of your hand. The intensity, penetration, and range of this light are impressive. Like the 214A, it has a full on full off switch (each and every time) that also half-taps to 40% output and then tactical strobe. The 6061 T6 aluminum housing is aggressively checkered, and the surface is finished using Type III Class 2 (Hard Coat) anodizing for maximum durability.
