INTRODUCTION Engineered with the latest cutting-edge technology, exceptional craftsmanship and unbeatable reliability.  Designed to be the ultimate search & rescue handheld flashlight that produces an astonishing 10,500 lumens with an extra-long throw up to 738 yards (675 meters)…that’s over 7 football fields! Ideal for professional first-responders, explorers or any other activities requiring a tremendous amount of illumination. Advanced thermal management with built-in cooling fan and Type III anodized aluminum body make dissipates heat efficiently without overheating. A sealed, rechargeable 8-cell circuit-protected 18650 lithium-ion battery pack (replaceable) is integrated into the light to provide many years of dependable service. The X10000 Destroyer is very easy to operate – simply depress the side button switch to turn on/off; then rotate the circular rotary ring surrounding the power switch to scroll through the 5 illumination settings (off, low, medium, high, strobe and SOS).
