The Inova X5 LED floodlight is a superbly engineered tool that delivers exceptional performance and durability, for a lifetime of owner satisfaction. With this advanced light, form truly follows function. While other LED flashlights are little more than LED technology that"s been force-fit into conventional products, the X5 is the result of an unrestricted flow of innovative, targeted engineering. Nothing is compromised or superfluous. Every choice--in optics, electronics, materials, thermal and power management, durability and usability--is driven by performance criteria. Individual reflectors surround each of the five LED lamps recessed in the X5"s patented stainless steel head. These powerful, shock-proof lamps project light up to 120 feet and operate from -30 to +60 degrees Celsius. The advanced lithium batteries included with the X5 generate up to 20 hours of light and have a shelf life of more than 10 years. The X5 lights the way, emitting pure, wavelength-specific color. Its body is 4.75 inches of precision-machined aircraft aluminum clad in military-grade, Type III anodizing. Critical mating surfaces are held to + or - 0.0005 inch tolerances, and exact compression sealing locks out moisture. The waterproof X5 is crush-proof to over 2000 pounds--which is to say, it"s practically indestructible This light"s patent-pending, three-mode switch cap enhances operation while ensuring waterproof integrity. The knurled cap, complete with lanyard hole, houses a non-slip, compression-sealed button. This smart, ergonomic design lets owners unleash the power of the X5 with one-handed control and prevents accidental activation in transport.
