You want a light that is reliable and rugged, of course, but for personal protection, a light needs to be compact, concealable, and comfortable to carry. Surefire’s E1D LED Defender epitomizes all of these requirements. It produces 300 lumens of felon-blinding light, weighs only 3.4 ounces, and measures only 4.5 inches long. It comes with a pocket clip for easy carry and serrated end caps to provide extra striking potential, and it has a low-output 5-lumen beam to help you read the menu in a dark restaurant or find the stuff you dropped between car seats. Retailing for $240, the E1D might sound too expensive. However, it will last longer than you will and is probably more dependable.
