Under 365nm UV you get to see all of the above (with much better contrast as there's minimal visible light interference), plus more items will show up. glow-in-the-dark items), vaseline glass, flora and fauna, and similar. As a rough guide, the 385-395nm devices are more than adequate for scorpions, finding fluid leaks, fossil hunting (including bones), urine identification, various minerals, charging of photo phosphorescent substances (i.e. The 385-395nm models will emit more visible light relative to the 365nm model which can sometimes be useful for navigational purposes.ĭifferent items will show up under the different wavelengths. If you're new to UV a 365nm model will have you surprised as the emitted light will appear DIM to the eyes, but excitation of objects is high and so fluorescence is correspondingly high. It's not necessarily the case of which is better, but more about which one suits your needs and requirements the best. 395nm+ (greater than 395nm is the visible light region, then moving into infrared). "nm" stands or nanometer as a measure of wavelength on the electromagnetic spectrum. ![]() Some of our models emit at 385-395nm UV wavelength range, and others emit at 365nm. So the only way to tell is to test how vividly objects fluoresce back to you. The test of this is fluorescence of targets rather than the “brightness” of the light source itself. You'll only be able to see the fluorescence effects, which will amaze you. Ultraviolet light that is beyond the visible spectrum which you cannot see. The V3 365nm will appear "dim" to you - some will even think it's a scam - but that's exactly what you're looking for in a "UV light". You won't be seeing very much non-useable visible light. More excitation occurs using the 365nm wavelength, meaning that with 365nm you'll see a lot more fluorescence and things will show which don't under higher wavelength UV such 390nm. This means that the maximum density of the flux peaks at 365nm and the filter ensures this over other UV 365nm flashlights in the market. ![]() So, coming back to what we just said - this light emits UV at 365nm wavelength. 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. Then put the UV lamp inside the goggles or glasses and shine it on the same fluorescing object through the lens.This is filtered ultraviolet light emitted at 365nm (nanometer) wavelength. ![]() Test your goggles or glasses by first shining a UV (shortwave or longwave) light on a mineral or other object that fluoresces brightly. Quick Science Investigation: Are you wondering if your safety goggles, sunglasses, or regular glasses will help protect your eyes against low-level ultraviolet light like our battery-operated UV lights? Many of these types of glasses have lenses made out of polycarbonate, a natural low-level UV light filter. Wear UV filtering goggles or glasses if using this low-level ultraviolet light source for extended periods. Note: UV light is the part of sun light that causes sunburns. The black light has a 6"-long bulb on the side and a mini flashlight on one end. This lamp produces UV light at 4 watts and 365-370nm to fluoresce longwave minerals. Use this longwave ultraviolet "black light" flashlight to test minerals for fluorescence and investigate fluorescence around your house.
