Ultimate Guide To Black Light Flashlights

Black light flashlights can be a lot of fun. I remember as a kid growing up in the Phoenix are of Arizona, using black light flashlights to hunt for scorpions at night. I also remember going to a rock and mineral museum and seeing minerals glow brilliantly under UV lights.

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.


Black Light Flashlight Bulbs

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.

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.

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!

3. Look For Pet Stains.  If you’ve ever had pets live indoors with you, then you know how difficult it is sometimes to locate the source of pet odors. With a black light flashlight your fight is over. Pet stains will glow under the UV light.

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!

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.

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.

7. For Your Next Party. Some of the neatest parties utilize the glowing effects of UV lights. Next time you throw a party, adopt this system. Turn out the lights, turn on the black lights and turn up the music! Watch everyone and everything around you glow!
