uvBeast V3 Flashlight
uvBeast makes the brightest ultraviolet flashlights we’ve seen. Their V3 light has three surface-mounted LEDs, which can project a UV beam 70 feet or more. Its light can be used for finding covered-up repairs and leaks, curing UV resins, and making phosphorescents glow brightly. It’s powered by two 18650 li-ion batteries.
