LED Lenser H14 Headlamps are versatile and powerful headlamps that can penetrate the deepest darkness without requiring the use of any hands. The bulb of these headlamps can swivel at almost any angle, and the third head strap makes the H14 extra stable, even during rigorous activities like spelunking and working with tools. The LED Lenser H-14 Head Lamp Flashlight makes use of LED Lenser's powerful Advanced Smart Light Technology (SLT) lighting system, which gives you eight different lighting modes that can all be easily accessed with a series of three presets. Smart Light Technology divides beam type into three programs, eight functions, and two energy modes; switch between Defense, Easy, and Professional programs by touching the power button four times and using a full click the fifth time. Each program has its own lighting functions that can be activated with a specific type of button press: Defense offers Full Power and Defense Strobe functions, Easy has Full Power, Dim, and Low Power functions, and Professional has all the Easy functions plus a Blink, SOS, and Strobe mode. These LED Lenser headlamps even have two energy modes, Constant Current and Energy Saving. The LED Lenser H14 Advanced SLT Headlamp uses a patented lens and reflector combination called the Advanced Focus System (AFS) for a beam that has both long-range focus and close-range diffusion lighting. What's more, a universal fastener allows you to clip the head lamp to a variety of surfaces and items, adding even more versatility to this hands-free headlamp.
