Black light flashlights are useful for spotting stains, identifying minerals, finding scorpions in the dark, and checking counterfeit money. To help you with all these functions and more, here are some black light flashlights to set you on your way.

A black light flashlight is a nifty device to own. If you’re a pet owner, then you know accidents happen. A black light will help you detect those accidents that you may not have even known were there. They will also come in handy when you stay at a hotel and want to check the bedding and the furniture for cleanliness. Home inspectors and professional cleaners even use them. Bank tellers use them to check counterfeit money. Regardless of the use, it’s not a bad idea to keep one handy, so here are some to consider.

Searching for the Right Black Light Flashlight 

Look for these features:

  • Versatility: The flashlight you choose should be versatile enough to be used for multiple applications. The stronger the LEDs, the better your chances are in discovering what you’re looking for, so be on the lookout for a flashlight that’s super bright and covers wide areas to reduce the time it takes to complete a thorough inspection.
  • Portable & Lightweight: The small, lightweight ones are great for traveling and keeping in your car. Pen lights are small enough to store in your pocket. Another thing to consider is waterproof flashlights for outdoor use.

Now, let’s shine a light on some of the best black light flashlights on the market!
