ESMARTER Zoomable UV LED Flashlight – 365nm & 395nm Blacklight Detection Torch

Reveal what the naked eye can't see with the ESMARTER Zoom UV LED Flashlight. Featuring dual ultraviolet wavelengths — 365nm and 395nm — this compact aluminum-body blacklight torch is engineered for high-sensitivity fluorescence detection. Whether you're authenticating documents, spotting pet stains, hunting scorpions in the dark, or checking for mineral fluorescence in ores, this versatile UV light delivers professional-grade results in a durable, pocket-friendly package.

Made in Mainland China.

Why Two UV Wavelengths?

365nm UV: The true dedicated detection spectrum. Invisible to the naked eye, 365nm produces minimal visible light leak, making it ideal for demanding inspection tasks such as detecting fluorescent agents, security codes, invisible ink, currency watermarks, passport authentication markings, and oil/fluid leakage. Works effectively even in ambient light, and excels in low-light environments.
395nm UV: Brighter purple glow that's excellent for everyday detection tasks — spotting pet (cat & dog) stains, nail polish curing, bed bug checks, scorpion hunting, and household cleaning inspections. Highly effective in dark environments.

Frequently Asked Questions

Q: What is the difference between the 365nm and 395nm UV wavelengths on this flashlight?

A: The 365nm wavelength is the true professional-grade detection spectrum — it emits minimal visible light, making it superior for detecting fluorescent agents, security watermarks, invisible ink, and authenticating currency or documents. The 395nm wavelength emits a brighter purple glow that is ideal for everyday tasks like locating pet stains, curing nail gel, and hunting scorpions in dark environments.

Q: What batteries does the ESMARTER UV flashlight use?

A: This UV flashlight is compatible with either one 18650 rechargeable battery or three AAA batteries, giving you flexible power options. Please note that batteries are not included and must be purchased separately.

Q: Is this UV flashlight waterproof?

A: Yes — this flashlight carries an IP65 waterproof rating, meaning it is protected against dust and low-pressure water jets, making it suitable for outdoor use in rain or wet conditions.

Q: Can this flashlight really detect pet urine stains?

A: Absolutely. Pet urine contains compounds that fluoresce under UV light. Simply turn off the lights, shine the UV flashlight over surfaces like carpets, furniture, or floors, and any stains will glow brightly, making them easy to locate and clean.

Q: Does the zoomable feature affect UV performance?

A: Yes, in a positive way. The adjustable zoom allows you to concentrate the UV beam for precise, targeted inspection of small areas, or widen it to scan larger surfaces quickly — adding great versatility for different detection tasks.
