I love these lights! In this set, you get two of them. They are very well built. Included batteries and they both worked really well. There are four modes for which turning on the lights. Took awhile to get use to it. Pushing it all the way down turns them on and off. Pushing down lightly will change different modes. Pulling the front of the lights will change how the light magnifies from 1x to 2000x. The four modes are bright, low, strobe, and UV lights. The strobe light can hurt your eyes. Really love these well made flashlights! Highly recommend!
