Thanks to their enhanced higher radiant intensity. This gives more power for uvBeast’s UV flashlight. Aside from usability on ambient lighting, you’ll be able to experience a wide flood effect from 20 to 30 feet ahead.

        What is a UV Flashlight?

        UV Flashlight, also known as black light, emits ultraviolet light which is not visible to human eye. Our human eye can only perceive the colors red, orange, yellow, green, blue, and violet. Ultraviolet is classified beyond violet.

        You may wonder why the source emits violet light. It is designed on a purpose for you to know if the flashlight is operating or not.

        Overexposure to ultraviolet light is risky for your eyes and your skin. While you see a little visible violet light, ultraviolet light is emitted throughout your surrounding without you knowing it.

        As a precautionary measure, you must not point the UV flashlight directly to your eyes. Do not shine it towards others eyes as well. Like a normal visible light, UV light can damage your eyes!

        How UV Flashlights Work?

        When you turn on the UV flashlight, white clothes, your teeth, and other items will glow in the dark.

        How UV Flashlights Work

        You may even see invisible stamps, invisible stains, and hidden security measures on a paper bill or identification cards. There are factors why such stufffluoresces under the presence of UV light.

        The majority of the glow in the dark items contain natural or synthetic phosphor. Phosphor reacts to radiation, one of it is the ultraviolet light.

        Upon reaction, the phosphor emits a visible light. Teeth, fingernails, and laundry detergents contain phosphor. Your teeth, fingernails and newly washed shirt will naturally glow under UV light.

        Some items may not contain phosphor. But it may contain materials with natural fluorescing capability. For instance, security threads from paper bills and the exoskeleton of scorpions naturally fluoresce in the presence of ultraviolet light.

        Uses of UV Flashlights

        Partygoers like to use fluorescent items for fun especially in clubs and bars. Detectives use UV flashlights to aid them in finding evidence.

        The government incorporates fluorescent items on bills and IDs for security measures.

        Others may not appreciate its usability, but you know its big significance to our world. Here is a range of activities where people integrates the use of UV flashlights.

        Best UV Flashlight Buying Guide

        While all UV flashlights do the same job, here’s a guide for you to know the slight variation among the UV flashlight competition.

        1. Radius of Illumination

        Some users prefer small radius of illumination just for stationary use, though most people prefer bigger radius.

        You may want to spot easily from a distance especially on scorpion hunting, pest hunting, and stain spotting. The radius of illumination all boils down to the number of LED bulbs used in a flashlight.

        There are three common number of LED bulbs found in the market: 12, 51, and 100. With 12 LED bulbs, expect illumination just around your standing point. This is good for document security check, money authentication, and ID verification.

        With 51 LED bulbs, expect illumination father from your standing points. This accommodates the need of illumination on scorpion hunting, insect spotting, and other wide-range activities.

        With 100 LED bulbs, expect higher intensity of illumination. Even if the room light is still switched on, the UV flashlight will still immensely fluoresce nearby items. And when the room is dark, expect bigger illumination than 51 LED bulbs.

        2. Battery

        Battery requirements and battery life depend on the number of LED bulbs used on a UV flashlight. If the manufacturer designs a UV flashlight holding a few battery, expect lower battery life on continuous usage.

        More battery requirement means more battery life, but the cost of the batteries may matter on your part.


        Reaching this section means you already understand the function and the core of UV lights. You will surely appreciate its essence when you open your mind more on what you can’t see.

        Believe it! There’s something you really can’t see that needs attention like stains, pests, and other unwanted stuff.

        With this review, you can finally choose the best UV flashlight which perfectly matches your preference.
