How Does A UV Flashlight Work

UV (Ultraviolet) makes your clothes glow in the dark because the substances in washing powder “Fluoresce” when the UV ray hit the surfaces.

Surface materials absorb the UV light, and re-radiate the energy with a longer wavelength.

There for you can see it.

Sometimes people also call it “blacklights” because human cant see thr UV coming from it.

What To Look For Wavelength Matters

Image Referenced Digikey.com

The most common commerical grade UV wavelength is 365nm.

This is widely used in fluoresce detection, currency & ID verification. As the wavelength shortens, the light rays become more damaging.

As the wavelength lengthens, the weaker it becomes.

Mode Selector

For anything UV related, there is no need to rush to get to the UV mode. You can take your time.

Fast UV access isnt a critical feature to look for.

However, quick access to Strobe mode & tail cap switch are important for a tactical light.

UV Light FAQ

Does UV Light Damage Human Eyes?

Large amount of UV exposure can damage the retina of the human eyes. Which is why wearing sunglasses helps blocking UV light.

As far as using UV light to detect invisible thing Can a UV flashlight kill bacteria? Yes… mostly for UVC rays with short wavelength around 100 – 280nm.

The shorter the wavelength the more damage it does like X ray & gamma rays. UVGI ( UV Germicidal Irradiation) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to destroy nucleic acid & disrupting their DNA, leaving them unable to perform vital cellular functions.

How much it can kill is based on

  • Exposure time
  • Line of sight
  • Intensity
  • UV dose
  • Other factors

Dosages for a 90% kill of most bacteria and viruses range from 2,000 to 8,000 μW·s/cm2.


Can UV Light Kill Coronavirus?

It’s not confirmed by the officials that UV rays can kill coronavirus on any surfaces, but UV light can expose questionable areas that require disinfection.

However, UVC (100-280nm) wavelength is commonly used to kill germs and virus.

UV and UVC have different wavelength. UVC is very damaging to human close up if exposed to it for a long time.
