The Coast LED Lenser H7 Focusing Headlamp is the only headlamp available with both adjustable focus and light dimming function. The H7 can be adjusted from a wide flood beam to a focused spot beam, with no dark and hot spots typically associated with focusing flashlights and headlamps. Variable Light Output Technology (VLT) enables the user to adjust the light output to suit the task, with a constant transition from maximum output to minimum output.
