The black HS4-A Minimus Variable-Output LED Headlamp from SureFire is a high-efficiency LED headlamp that provides warm-colored light designed to penetrate dust and fog. With its smooth wide beam optimized for your field of view, the output is adjustable from 0 to 100 lumens with a knurled right-hand control dial. Its light assembly head rotates up to 90° for precise positioning. The battery compartment, located in the tilt-control knob, features a short leash to prevent the cover from being lost. An emergency, long-running SOS beacon function continually cycles through the Morse Code sequence. The 1" wide adjustable headband features a moisture-wicking Breathe-O-Prene forehead pad for comfortable wear over long periods of use.

    Comments about SureFire HS4-A Minimus Variable-Output LED Headlamp:

    This is a great headlamp. It is very bright and I am a huge fan of Surefire products. It's also great that you can put AA batteries in it, vs. the expensive CR123 batteries that most of their flashlight line takes. It is pretty heavy though. It's built like a tank and after 20-30 minutes of wearing it causes a headache. I have multiple Petzl headlamps and they don't put out the amount of light that this Surefire headlamp does, but they are a lot more comfortable. It is an awesome headlamp but it is just too heavy for my tastes. I sent it back. Hopefully Surefire comes out with a lighter model.
