No more fumbling to safely unlock the car door or house, read a menu in a dimly lit restaurant or light the way down an aisle in a movie theater. The bright beam illuminates a path in the dark or poorly light room. Indoor or out. The Micro-Light Ultra easily attaches to a key ring or zipper. At less than 2.63” x 1.06” in size and weighing less than 0.5 oz, the Micro Light Ultra is convenient to carry with you at all times.
