An improvement

The plastic Surefire I already had employs a different switch ( tighten the tail cap and it comes on . Press button with loose cap for momentary use .
This light is off even with the tailcap tightened . The button controls both constant and momentary modes . The loosened tail cap acts as a safety ; to accidentally turn on the light, you'd have to tighten the tail cap and push the button . This is a much safer system for a light that can get hot in use .
The metal body is thinner . The light is brighter .
Now I need to give my plastic one to someone .
I like having the best but must point out that a Mini Maglite LED 2 AA cell light is fine for walking a dog and most other situations , so those on a budget may be able to do without a Surefire . Of course, if you need to fire a pistol, discombumerate at attacker or find your way out of a burning building, you want a Surefire of one model or another .

Best One Yet

The L4 is my 3rd SureFire light. I also have a 6PX Pro and an M951. Of the three, the L4 is my favorite. I purchased it to go with my CCW for EDC. It is bright, unobtrusive, and easy to conceal. I spent some time shooting with it this weekend and it is much more comfortable to to use than the 6PX. It may have been my best purchase this year.

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!!
