If the light is not emitting at the right wavelength, then it will not illuminate the invisible elements you want to see. The main element you want to look at is the wavelength of a UV light.A UV light can help you spot counterfeit bills, find bodily fluid stains, inspect minerals and gemstones, and look for certain insects and reptiles. What can you use a UV light for? There are a number of reasons why you may need to see more than meets the eye. A wavelength of around 360 or 365 nanometers is recommended. Keep in mind that if you purchase a UV light with the wrong wavelength, you may not be able to illuminate the things you want to see with the light. If that is your goal, you will need a UV light that emits at 400 nanometers or below. Not all UV lights can induce fluorescence. Similar to visible light, UV light is measured on a wavelength in nanometers. However, instead of emitting the standard light you’d use when you can’t see in the dark, this kind of light uses ultraviolet light from LED technology.īe sure to get a UV light that has the correct wavelength for what you need it for. This means that the UV lights help to detect these elements.Ī UV light often looks like a regular flashlight that emits white light. However, when a UV light comes into contact with certain elements, such as paint, minerals, dyes and bodily fluids, it begins to fluorescence. This type of light is not visible to humans. UV, which stands for ultraviolet, is a kind of radiation or light energy.

If you’ve ever wanted to see more than you can with the naked eye, a UV light can help.
