An authentic 365 nm flashlight will make the material glow brightly. If the light is ineffective or dim, the flashlight may be counterfeit or low-quality.<\/li>\r\n\r\n<li><strong>Alternative method<\/strong>: Use a piece of white paper with fluorescent ink or a piece of currency.

A genuine flashlight should be able to illuminate them clearly.<\/li>\r\n\r\n<li><strong>Measure brightness<\/strong>: Shine the flashlight at an object and check if it produces the desired intensity.
