I have been into flash lights long before led was thought of. I have always ran Surefire and just started buying some of Malkoff devices. I like running 18650 and cr 123. Where do you start these days with so much product. I am looking for a powerful 1 bat 18650 and a 3 or 4 18650 light.Quality is important which company's stand out on top. I do like to buy USA, Not a big fan of China.
