12W UV Flashlight 365/395nm Oil Stain Inspection & Curing Lamp

12W UV Flashlight — Multi-Wavelength Inspection & UV Curing Light

Whether you're detecting hidden stains, verifying UV-curable adhesives, or conducting professional inspections, this powerful 12W UV LED flashlight delivers high-intensity ultraviolet output across four selectable wavelengths: 365nm, 385nm, 395nm, and 405nm. Built for professionals who demand precision, this compact torch combines imported high-power UV LED technology with a rugged, aircraft-grade aluminum alloy body.

Key Features

• Multi-Wavelength Options: Choose from 365nm, 385nm, 395nm, or 405nm UV output to suit your specific application — from oil stain detection and fluorescence inspection to UV adhesive curing.
• High Radiant Power: Delivers 4,000–5,000 mW of UV radiation power, ensuring fast and effective results across professional use cases.
• Imported High-Power UV LED: Large-sized, high-efficiency ultraviolet LED bead for consistent, reliable performance.
• Specialized Optics: Fitted with a black UV-pass filter and specialized lens for focused, effective UV output (note: 365nm and 395nm curing variants come without the black filter).
• Constant Current Circuit: Low-voltage and temperature-control protection circuit ensures stable output and long LED lifespan.
• Premium Aluminum Body: CNC-machined aluminum alloy with hard anodized finish — lightweight yet highly durable at approximately 90g.

Frequently Asked Questions

Q: What is the difference between the 365nm and 395nm UV flashlight options?

A: The 365nm wavelength is closer to "true UV" and produces very little visible violet light, making it ideal for professional fluorescence inspection, detecting hidden stains, and examining documents or minerals. The 395nm wavelength is slightly more visible (mild violet glow) and is popular for UV resin curing, scorpion hunting, and general UV applications. Both are powerful at 12W, but the curing-specific 365nm and 395nm versions are supplied without the black filter.

Q: Does this UV flashlight come with a battery?

A: Yes. The package includes one 21700 high-capacity lithium battery and a USB 5V 2A single-slot charger, so you can get started right away without purchasing additional accessories.

Q: Is this UV lamp safe to use?

A: This is a high-power professional UV flashlight. Always avoid looking directly into the UV beam and do not shine it on exposed skin for prolonged periods. Use UV-protective eyewear when operating the lamp, especially during extended inspection or curing sessions. The CE-certified constant current circuit helps prevent overheating for safer operation.

Q: Can this lamp cure UV adhesives and resins?

A: Yes. The 365nm and 395nm wavelength versions are particularly effective for curing UV-sensitive adhesives, resins, and gel coatings. The high radiant power output of 4,000–5,000 mW ensures fast and thorough curing results in professional settings.
