SureFire Flash Light

With the recent black out the we experience here, I told my husband when he called me that we need to get another flash light that will give out more light and don't have shadow or ring-like that appears when you turn it on. I was suggesting like the Surefire new flashlights are energy efficient. One sure thing of this type of flash light is that it has the capability to maintain consistent levels of light output for as long as possible. My husband can use this too when he goes to night time training in his job.
