✅ Key Features

• 395nm Ultraviolet Wavelength: Delivers a high-intensity UV beam (395–400nm) that makes invisible residues, stains, and fluorescent markings instantly visible under the purple light.
• Zoomable / Telescopic Focus: Adjustable zoom lets you switch between wide-area illumination and a focused beam — perfect for scanning large surfaces or homing in on a specific spot.
• 3 Lighting Modes: Cycle through Strong Light → Low Light → Strobe to match any situation or environment.
• USB Rechargeable with Overcharge Protection: Powered by a built-in 1200mAh 18650 Li-ion battery. Charges fully in ~3 hours via Micro-USB. The indicator light turns red when power is low and green when fully charged — charging stops automatically when full.
• IPX4 Waterproof Rating: Splash-resistant construction keeps moisture away from internal components, extending the flashlight's lifespan.
• Durable Aluminum Alloy Body: Anodized aluminum construction is lightweight (~71g), corrosion-resistant, and aids heat dissipation for longer, safer operation.

Frequently Asked Questions

Q: What does 395nm UV wavelength mean and is this flashlight safe to use?

A: 395nm refers to the near-UV wavelength of the light emitted, which sits at the boundary between UV and visible violet light. This range is effective at making fluorescent substances visible — such as pet stains, security markings, and certain minerals — while being one of the safer UV wavelength ranges for general use. Avoid shining directly into eyes and keep out of reach of children. This flashlight has been wavelength-tested and meets CCC, CE, and RoHS certification standards.

Q: How do I know when the UV flashlight is fully charged?

A: The built-in LED indicator tells you everything. While charging, the indicator light glows red. Once the battery is fully charged, it switches to green — and the flashlight automatically stops charging to prevent overcharging, protecting the battery's lifespan.

Q: Can this UV flashlight detect pet urine on carpets and upholstery?

A: Yes! The 395nm UV beam causes the organic compounds in pet urine to fluoresce, making invisible stains glow brightly under the blacklight — even old, dried stains that have already been cleaned. Simply dim or turn off the room lights, hold the flashlight close to the surface, and scan slowly for any glowing spots.

Q: How long does the battery last on a single charge?

A: The built-in 18650 Li-ion battery (1200mAh) provides 3 to 8 hours of use per full charge, depending on which lighting mode is selected. Strong light mode will consume power faster, while low light mode extends battery life significantly. A full recharge takes approximately 3 hours via the included Micro-USB cable.

Q: Is this flashlight waterproof?

A: This UV flashlight carries an IPX4 waterproof rating, meaning it is splash-resistant from any direction. It can handle light rain or accidental splashes, but should not be submerged in water.
