LBJD 365NM Black Light Flashlite, High Power UV Blacklight Flashlights with Professional Filtered 3 LED Bead, for Pet Urine Detection, Dry Stains, Gemstone Observation(8.6'' 11.4'') - V7202305LBJD

• WHY LBJD V7 365nm BLACK LIGHT FLASHLIGHT? -- Black lights are necessary to observe fluorescence because the fluorescent glow is usually too dim to be seen without them. Most fluorescence is strongest in the wavelengths around 360nm. Compared to most other 365nm lights, this LBJD V7 flashlight produces very very little visible light to mask or interfere with the resulting fluorescence. WHY BLACK LENS? -- Black lens can block visible light but permit the passage of ultraviolet wavelength. Ultraviolet radiation is invisible to the human eye, but illuminating certain materials with UV radiation causes the emission of visible light, causing these substances to glow with various colors. 3PCS PROFESSIONAL GRADE FILTERED LEDs -- The V7 365nm is eqipped with 3 LEDs at 1080 mA. We examine each UV LED for the correct color temperature and UV output range. Each UV LED is made exactly to LBJD specifications. And with a high density flux at 365nm UV emitted, you'll struggle to see any visible light! EXTENSION TUBE, ALUMINUM ALLOY BODY -- This black light flashlite will come with 2 batteries and an extension tube so you can add a third battery if desired, the real king of all the 365nm uv flashlights, very practical function. Made with durable black HAIII Aluminium Material, this uv flashlight can survive accidental drops, temporary water submersion, and perform reliably under any condition.
