I love this flashlight because it has 3 separate light modes. Bright white/yellow/ultraviolet lights and with a half click of the button it alternates between lights. The ultraviolet is handy when you want to check if the hotel sheets are clean from a number of unseen contaminates urine/blood/semen. The bright light is a bright working flashlight and the yellow is a soft yellow light which I'd good checking Jem's for cracks or splits. One great low price for 3 separate flashlights. Recommend this highly.
