uvBeast New V3 365nm Black Light UV Flashlight – HIGH Definition Ultraviolet - HIGH Power and Long Range Professional Grade Beam Best for Professional/Commercial Use – USA Stock

No Standalone lithium batteries are sold with the product. Batteries are pre-installed in the equipment and the insulation tab needs to be removed
WHY uvBeast V3 365nm? Our users wanted more intense 365nm UV and more range for better results. Our new design intentionally aims to fill those gaps. (1) The popular and in-demand V3 spec now emits even higher quality UV at 365nm wavelength. (2) More bang for your buck with filtered UV. This isn’t cheaper unfiltered UV. (3) Unbeatable long range (60 feet+) and a high intensity 365nm beam unlike others.
PROFESSIONAL GRADE FILTERED 365nm. This is High Flux Density 365nm wavelength that professionals use. We know. We supply them. This is NOT to be confused with longer wave 395nm devices. Nor is it to be confused with unfiltered 365nm UV. Most excitation occurs at 365nm which means you’re getting superior results to most users. 395nm cannot compete with 365nm devices. The on-board UV filter blocks unwanted visible light but allows max transmission of pure 365nm UV. This is UV at its purest
OUR HIGHEST INTENSITY 365nm DEVICE. Higher UV Flux Density than most 365nm devices currently on the market. 365nm is the gold standard for UV flashlights. There's limited market choice in high flux density 365nm UV. So we made one with superior UV. The V3 365nm has TRIPLE LEDs (manufactured in S Korea) at 1000 mA each emitting 1800 uW/cm2 of UV radiant intensity. That’s a whopping total of 5400 uW/cm2 of UV intensity at 365nm
UNLIKE OTHERS THIS IS LONG RANGE 365nm UV. A high intensity 365nm device which can emit a beam out to 60 feet plus is hard to find. We know, because our users have told us. We’ve filled this gap with the V3 365nm to change the game for those who want results at long range with UV 365nm purity
