5. The UVP 95-0158-04 Mini UV Lamp (Best UV Light For Minerals)

Best Black Light Flashlight To Make Minerals Glow

Unlike the other blacklight flashlights reviewed in this post, the UVP light emits short wave UV light. 

The UVP Mini UV Lamp is currently one of the most affordable portable short wave UV field lamps. It’s a basic, no frills black light field lamp.  It’s small and lightweight size make it ideal for taking it along with you out into the field. 

The downside, however, is that it is only a 4 Watt UV lamp, which means you will need to be close to the minerals with the UV lamp to see them glow.  This is not the best UV lamp if you simply want to walk around shining your UV light on the ground to find minerals that glow.

  • 4 Watt
  • Short wave Ultraviolet Light
  • Small/ Lightweight
  • 4 AA Battery powered

7 Reasons To Own A LED UV Black Light Flashlight

1. Make Minerals glow.  I love doing this. And I’ve thought its one of the coolest things ever since I was a kid.  Just remember that there are a limited number of minerals that will glow with these long wave UV light black lights. The UVP shortwave black light flashlight is the best option for minerals.

2. Hunt For Scorpions. This is another fun activity if you’re ever in a part of the world that has scorpions. It’s amazing how these creatures literally glow under black light. Just be careful…don get too close when you do find one! The KOBRA UV Black Light Flashlight will be the best for heading out to the desert to look for scorpions.

 4. Inspect Hotel Rooms.  Have you ever watched those specials on TV where they walk into a hotel room, turn out the lights and turn on a black light flashlight.  Only then are you able to see the horror of stains left behind by other hotel guests.  Take one with you on your next trip and make sure you have a thoroughly clean room! The blacklight flashlight made by iLumens is the best for this use.

5. Look For Bed Bugs.  Now, I’ve never done this myself, but I have been told that you can use a black light flashlight to look for bedbugs.  The idea of this creeps me out, and may be just another reason to take a black light along with you on your next hotel stay. iLumens makes the best blacklight for bed bugs as well.

6. Check For Counterfeit Money.  Have you ever seen cashiers use a black light to inspect large denomination bills?  They are looking for counterfeit money.  Real bills are designed with special anti-counterfeit characteristics that will glow under the light of a UV light. Counterfeit money will be easy to see with the Escolite UV Black Light Flashlight.

What Are Black Light Flashlights

Black lights are llamps that emit an utraviolet light. Ultraviolet light is a type of electromagnetic radiation, just like radio waves, infrared, X-rays and gamma-rays. Ultraviolet light is not visible to the human eye.

Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies called the electromagnetic spectrum. It’s on this spectrum that we find UV light, X-rays and gamma rays.

Ultraviolet light, or black light, falls in the range of the electromagnetic spectrum between visible light and X-rays.

When it comes to black light flashlights, there are two types. There are the more expensive short wave black light flashlights, and there are the less expensive long wave black light flashlights. I wrote an in depth post explaining the difference between long wave and short wave ultraviolet light.  Wikipedia also has a more technical description of what black light is here.

How Do Black Light Flashlights Work?

When it comes to talking about black light, there are typically two types of UV lamps available.  There are florescent black light bulbs, and there are the newer, more common LED black light bulbs. Typically, your less expensive long wave UV light flashlights will use LED black light bulbs.

Of course the effectiveness of the UV black light bulb depends on its construction. For the best black light, look for bulbs with an output between 365 to 368 nm. Again, this falls in the long wave UV range, which makes whites and fluorescent colors glow.

Fluorescent black light bulbs are within this output range, and it only takes one bulb to get the black light effect. LED black lights on the other hand usually have a higher output of around 385 to 400 nm. This too falls into the long wave UV light range, but is a little more powerful than the florescent bulbs.

What Is The Difference Between Short Wave UV Light And Long Wave UV light?


Long wave Ultraviolet Light

Long wave UV lights have filters which screen out a lot of the visible light they produce, but not all.  These filters are generally inexpensive to buy for that reason. Because of that, the black lights we use as hobbyists are a great way to produce long wave UV light.  In nature, long wave UV light is present in sunlight and is not harmful to humans.


Short Wave Ultraviolet Light

There are two types of short wave UV light; filtered and unfiltered. As you can imagine, unfiltered UV lights allow a large amount of visible light through, rendering it useless for making many minerals glow.  Too much visible light passes through and drowns out the “glow”.  

Filtered short wave UV lights on the other hand, filter out almost all visible light, allowing only shortwave ultraviolet light to pass through.  These filters can be somewhat expensive which is why high quality shortwave UV lights are so expensive when compared to unfiltered long wave UV lights.

Since most of the visible light is filtered, and only UV light is passing through, short wave ultraviolet lights are the best black lights for minerals.
