In A Nutshell
Scorpio Premium is the best UV flashlight on the market. It has 51 UV 395 nm LED blacklight flashlight bulbs that make it brighter than competitors in a similar price range.
- Streamlight Twin-Task UV Light and Gallium Indium Nitride UV flashlight are also high quality Ultraviolet LED flashlights for the price.
Ultraviolet light is the preferred light source of TV crime scene investigators on the hunt for body fluids. Distinguished by its trademark purple glow, it has a wavelength that is shorter than visible light but longer than X-rays, in the range of 10 nanometers to 400 nanometers. It is useful to make fluorescent substances glow that can’t otherwise be seen by the naked eye. Portable UV light used to be too unwieldy and expensive for consumer purposes, but that all changed after ultraviolet light emitting LEDs were introduced in 2006. They are now widely available in flashlight form.
These flashlights are most often used to detect fraudulent documents such as fake IDs, see watermarks, read invisible ink or investigate crime scenes. They can also be used to “fluoresce” scorpions and certain types of minerals, and charge “glow-in-the-dark” object like fishing lures. Use them to protect your businesses from counterfeit money and your home from pointy tailed pests.
Here are the best rated, most reliable UV flashlights available:
Scorpio Premium 51 LED 395 nm UV Flashlight
This 51 LED is 30% brighter than the other flashlights on the market and has a high quality UV light.. At 395 nanometers (nm) the Scorpio Premium provides the upper end of the wavelength spectrum for UV light. The UV bulbs are rated to last over 100,000 hours and the body is made of durable aluminum with “O” rings for water resistance.
At 5.8″ x 1.42″ it is quite portable and easy to use for employees. It is one of the best reviewed ultraviolet LED flashlights on Amazon and perfect for scorpion hunting.
Gallium Indium Nitride UV Flashlight
This Gallium Indium Nitride UV flashlight gets great ratings from Amazon buyers, so we thought we’d include it here. Reviewers were impressed by the flashlight’s durability, and the fact that it emits 365 nm UV light, which is at the very edge of our visible range. The light from this flashlight appears as a dim purple-blue to the eye, but when it shines on items that fluoresce they light up brightly.
It uses three AAA batteries — we recommend using low self-discharge AAA rechargeable batteries like Eneloop Pros in this flashlight.
Streamlight 51018 Twin-Task UV Flashlight
Streamlight is one of the few companies that still make flashlights in the U.S., and their products get consistently high ratings.
If you need reliable flashlight that provides both an ultraviolet mode and white light mode, the Streamlight Twin-Task UV Light is a great choice. It has six 390nm UV LEDs for ultraviolet light, and an ultra-bright xenon bulb for white light. It’s fully waterproof, and one meter impact resistance tested.
