![]() What a UV flashlight will not do, it must be noted, is provide any significant illumination such as one would expect from a standard flashlight. Also consider the power source of your prospective UV light some such flashlights partner a USB cable and rechargeable battery, while others burn through traditional batteries quickly. Some units have single bulbs or several small LEDs and are fine for use when they can be held close to the surface in question, while others use larger batteries of bulbs to cast a beam across much more distance. Next consider how and where you will use the light. Some options can easily tuck into a glove box or even a pocket, while others are large enough to require a bit more room, though still stowing easily in a bag. When choosing a UV light, consider where you will store the device. Both the small cost and size of these devices is principally thanks to recent advances in LED technology, which allows for the efficient production of potent ultraviolet light. These lights are not expensive tools, and most UV flashlights are also of relatively small size. UV light itself is invisible to the naked human eye, but is nonetheless quite helpful in illuminating many substances thanks to the unique luminescent properties it creates when reflected by everything from gemstones to the bodies of certain insects. Of all the models on our list, the LightFE UV301D is the only one suitable for detecting minerals in rocks, since it outputs a 365-nm wavelength, as compared to the roughly 395-nm wavelength of the others.Īn ultraviolet flashlight puts the power to control a unique portion of the light spectrum right in your hand. Of these, the Dulex DX-502B and TaoTronics TT-FL002 seem to produce the highest fluorescence in bodily fluids, and the former even includes a pair of yellow glasses to further boost contrast between the detected fluid and whatever surface it is on. The TaoTronics TT-FL002, McDoer 100 LED, Dulex DX-502B, LEDwholesalers 7202UV395, and Escolite Detector are all reasonably priced and found to be reliable enough for most consumer's needs. The average home user who may only periodically have need for a UV light when they are hunting for the source of an odor in their home or scouring their yard for scorpions can probably easily get by with one of the more economical options on our list. It is marketed as having an 80-foot beam throw, but there are many user claims of it projecting significantly further than that, so if that is important to you, it might be your best option. However, the UVBeast V3 might just have the strongest beam out of all of the models on our list. We also like the Nitecore CU6 Chameleon because it eliminates the need to carry multiple flashlights, since it has red, green, blue, and white LEDs. Of these, the Streamlight Stylus Pro and LightFE UV301D are best if you will be keeping them in a toolbox or anywhere else where they may get mixed up with other flashlights, since they both have purple bezels that makes them easy to differentiate from traditional units. For those looking for a well-built model that can withstand the rigors of daily high-volume or field use, or for anyone who is rough on their tools, we recommend the Streamlight Stylus Pro, Jaxman U1 Mini, Nitecore CU6 Chameleon, UVBeast V3, and LightFE UV301D, which are all built very tough. UV flashlights can be used to detect counterfeit currencies or IDs, find bodily fluids, determine mineral content in rocks, spot fluorescent dye leaks, and more. ![]() At the other end of the spectrum, the Dulex DX-502B is still our favorite low-cost option from a reliable manufacturer. We also really like the Weltool M2, partly because you can choose from focused and even-beam versions. ![]() It even offers an extension tube, so you can use two batteries at once and greatly increase its duty cycle. The results of our search include the Convoy C8+, which is about the best performer you'll find. ![]() We removed a handful of no-name models from questionable brands, and consulted some dedicated UV flashlight enthusiasts to find the experts' picks.
