The K3 is a palm-sized aluminum flashlight with an 800-lumen LED that outperforms a smartphone light for nighttime use. It includes a UV emitter useful for spotting counterfeit currency, illuminating glow-in-the-dark paint, activating UV adhesive, and detecting leaks. It adds a laser pointer for distant pointing and a multi-color RGB LED for creative or party lighting. A concealed bottom igniter functions as a lighter for starting fires.
