uvBeast V3 365nm Black Light UV Flashlight – High Definition Ultraviolet - HIgh Power and Long Range Professional Grade Beam Best for Professional/Commercial Use – USA Stock
- Ready for operation out of the box
- 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

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
The Ultimate Guide to Choosing UV Lights for Minerals
Do you love collecting glowing rocks? Many minerals shine brightly under ultraviolet (UV) light. This is called fluorescence. To see this hidden magic, you need the right tools. This guide helps you pick the best UV light for your collection.
1. Key Features to Look For
First, check the wavelength. UV lights come in two main types: Shortwave (SW) and Longwave (LW). Most fluorescent minerals react best to shortwave light. You should look for a light that offers both or specifically targets shortwave if you want to see the most colors.
- Wavelength: 254nm is best for shortwave, while 365nm is standard for longwave.
- Portability: Battery-powered lights let you explore caves or fields.
- Power Output: Stronger lights reveal dimmer minerals.
2. Important Materials
Quality matters for your equipment. Look for a sturdy metal casing, usually made of aluminum. It protects the delicate internal bulbs. The filter glass is also vital. A good filter blocks visible light so only the UV light hits the mineral. This makes the glow look much sharper and clearer.
3. Factors That Improve or Reduce Quality
The quality of your experience depends on the light’s filter. Cheap lights often use plastic filters. These fade quickly and let too much purple light leak out. High-quality lights use glass filters that last for years. Also, battery life plays a huge role. If your light dims after ten minutes, you will miss out on the fun.
4. User Experience and Use Cases
Using a UV light is easy. You simply point the light at your mineral in a dark room. You will see colors like neon green, bright red, or electric blue. Collectors use these lights to identify rocks or just to enjoy the beauty of their display. Always wear UV-rated safety glasses. UV light can hurt your eyes if you look at it directly.
10 Frequently Asked Questions
Q: Do all minerals glow?
A: No, only certain minerals contain activator elements that cause fluorescence.
Q: Is shortwave or longwave better?
A: Shortwave is better for most minerals, but longwave shows different colors in others.
Q: Can I use a regular blacklight?
A: A standard blacklight is longwave. It works for some rocks but will miss many others.
Q: Why do I need safety glasses?
A: UV rays are harmful to your eyes. Always protect your vision.
Q: How do I know if my mineral is fluorescent?
A: You must test it under a UV light in a dark space.
Q: Are LED UV lights better than bulbs?
A: LEDs last longer and use less power, but shortwave LEDs are still quite expensive.
Q: Can I take photos of my glowing minerals?
A: Yes, use a tripod and a long exposure setting on your camera.
Q: Does the color of the glow change?
A: Yes, the color depends on the minerals inside the rock, such as manganese or uranium.
Q: How long do the batteries usually last?
A: This depends on the model. Most high-quality portable lights last for several hours of use.
Q: Where is the best place to use a UV light?
A: Use it in a completely dark room or outside at night for the best results.
