UV Flashlight Tester
by Window Alert
Make sure your decals and UV Liquid still glow brilliantly for wild birds. WindowAlert decals and WindowAlert UV liquid have a coating that brilliantly reflects ultraviolet sunlight. This coating will degrade when exposed to the elements. This 365 nanometer LED UV Black light flashlight can be used to test the quality, or fading of WindowAlert products. Four AAA batteries not included.
