365nm UV LED 3 Watt Flashlight

Our newest 3 watt UVA flashlight with a wavelength of 365 nm (nanometers) is particularly effective for charging glow-in-the-dark items and for exciting fluorescent materials. This wavelength tends to produce a more vivid and distinct fluorescent effect, making it ideal for revealing brighter colors for glow-in-the-dark powders and glow paint, the natural fluorescence in certain minerals, verifying the authenticity of documents, or for artistic and decorative purposes.

Using a 365 nm UV flashlight can be a fascinating way to explore the world of fluorescence and phosphorescence, whether for practical purposes or simply for the enjoyment of seeing things light up in unique ways.

Other Applications

  • Detecting Counterfeit Money: Many currencies have UV-reactive strips or markings to verify their authenticity.
  • Forensic Analysis: UV light can help detect bodily fluids like blood, sweat, or urine, which is often used in crime scene investigations.
  • Sanitation Inspection: UV light can reveal cleanliness levels in environments like kitchens or bathrooms by highlighting organic materials.
  • Leak Detection: Certain types of leaks, like those in automotive or HVAC systems, can be detected by adding a UV-reactive dye to the system and then using a UV flashlight to locate the leak.
  • Scorpion Hunting: Scorpions glow under UV light, making them easier to spot at night.
  • Mineral and Gemstone Identification: Some minerals and gemstones fluoresce under UV light, aiding in identification and collection.
  • Art and Antiques Verification: UV light can reveal restorations or modifications in art and antiques.
  • Fluorescent Dye Tracing: In environmental studies, UV-reactive dyes can be used to trace water flow or leaks.
  • Authentication of Documents: Passports, ID cards, and certain legal documents often have UV-reactive features to prevent forgery.
  • Curing Resins and Adhesives: UV light at 365nm is effective for rapidly curing specific resins and adhesives in crafting and manufacturing. However, it's crucial to use resins and adhesives formulated for UV curing, as they're made to solidify under UV light. Standard resin epoxies won't harden with UV exposure.
  • Pest Control: Detecting rodent or pet urine, which fluoresces under UV light, helps in pest control and cleanup.
  • Checking HVAC Systems: UV lights can be used to check for proper operation of UV air purifiers in HVAC systems.

Remember to use UV flashlights safely, as prolonged exposure to UV light can be harmful to eyes and skin.
