Great Wider Beam

I really like the fact that the L4 has a wider beam than some of my other surefire lights. I carry this in my car at all times. I've also taken it camping with me. The long lasting battery is a plus. I rarely change out batteries. Great size too.

The L4 LumaMax is a terrific flashlight! It perfectly satisfied my need for a compact but very bright flashlight. It is more powerful and more effective than other manufacturer's flashlights several times its size. It's quality is typical Surefire!!
