Some of our models emit at 385-395nm UV wavelength range, and others emit at 365nm. This explains why you'll often hear users say, "This light shows things up that my other lights don't." The reason is because under a broader band you'll see a greater variety of items of interest fluoresce. Some things will show up under that type of UV while others won't. They will not cause the necessary or sufficient excitation required for objects to fluoresce.Īnother point of note is that often a narrow band such as 390-395nm or 395-400nm is not ideal to fluoresce many items of interest which you may require. Many UV flashlights in the market are 395, 400, 405, 410 and often can be marketed as "395nm" UV lights but in reality emit a substantial amount of 400nm+ UV, which will stray too much into the visible light region - visible light won't fluoresce items, which means not much is going is going to show up! Purple party lights are often characterized by this, and you don't want to have these in your UV flashlight. This is good news! 395nm+ is visible light - which you don't need. This means that the maximum density of the flux (or the majority of the UV emitted) is between this band. So, coming back to what we just said - this light emits UV in the 385-395nm wavelength range. Below this is the "ultra" violet region which the human eye cannot see. Note that visible light can start at 395nm+ which is the "violet" region - the first region in the rainbow. This is ultraviolet light emitted in the 385-395nm (nanometer) band. But, folks have our AA models in return for blindingly good UV! So, here’s our give-back to you. In the long-run, that’s not exactly cheap. Every 12-14 hours of use you’ll need to buy six AA alkaline batteries. Why? The costs add up with the AA models. Since 2015 a lot of folks (and we mean a-lot) have told us they love the uvBeast, BUT please make a rechargeable one, they said. The Most Powerful And Best Regarded UV Flashlight V3 now uses SMD tech to pump higher intensity UV delivered at 3.6 Amps (3x1.2A LEDs) – just when you thought that our UV couldn’t get any more intense! Other models use the older DIP type LEDs (Dual Inline Package) encased in a bulb. You’ll mostly be on your hands-n-knees, in the dark! You’ll need total darkness, be within 2 feet, and literally on top of, your area of interest. Cant wait to try this light with the extension and extra battery - to see how much longer search time will we get.”įor most of us, they’re just too damn dim! They’re impractical. I do like the removal batteries versus internal charging, so that I can continue using with other batteries. We will be ordering a 2nd set of batteries to use while first set is charging in the included charger. It doesn't get dim though, it just goes out. Battery life lasts a few hours with continuous use. Has a little weight to it, but well worth it for light produced. Scanning a rooms carpets and walls is a quick swipe, nothing hides from this light. There is no missing the creepy crawlers! I also use UV for house cleaning but the uvBeast is too strong for close up viewing on kitchen cabinets (especially on white). We have 4 other brands of UV flashlights and this Beast puts them all to shame! Super bright light shines farther than any others, even when combined. “Gf This uvBeast is the BEST! Main purpose for using UV lights is for finding scorpions (and any rocks that are LW florescent).
