Tips When Buying a UV LED Flashlight

  • Lens Type: Depending on the use you want to give the flashlight, you may find flashlights that offer different modes of use. The flashlights that allow you to make the change between ultraviolet light and LED light will give you more versatility.
  • Housing: Keep in mind the housing material that covers it, as it will be your protection against external agents such as dust or rain. Good flashlights, in general, are coated with some aluminum alloy. If the use you are going to give it is going to be domestic, this factor is not so decisive.
  • Size: another important factor to consider when buying a UV flashlight is the size. Keep in mind that, larger lanterns usually have a larger number of diodes to be more powerful. This does not mean that the quality is better, everything will depend on the quality of the LEDs and the diodes it incorporates. Anyway, if you need it for outdoor use, you better lean towards a more powerful one.
  • Wavelength: ultraviolet radiation reaches a wavelength that is between 15 nanometers (nm) and 400 nm. Flashlights that offer a wavelength of 365 nm are more precise than those that offer longer lengths. Being lower, it allows the detection of small details, which in some tasks such as detection of counterfeits can be important. Its use is usually more professional than those of 395 nm.
