How to choose a suitable UV flashlight ?

UV flashlight is a special lighting tool that emits uv light, primarily used to excite fluorescent substances, making invisible traces visible to the naked eye. It is commonly used in scenarios such as currency verification, detection of fluorescent agents, identification of jade, and locating pet urine.

What’s the different of 365nm UV led and 395nm UV led in UV flashlight ?

When purchasing UV flashlight, UV wavelength is the most crucial parameter, as it directly determines the clarity of the detection effect.

1.365nm UV led:

Purer effect: The emitted UV light is purer, with little visible UV light to the naked eye, a dark background, and a very obvious fluorescence response.

Application scenarios: Suitable for professional appraisal, such as detecting internal flaws in jade, identifying anti-counterfeiting marks on banknotes, and conducting precise fluorescent agent testing.

Features: Usually priced slightly higher, suitable for users who have high requirements for detection accuracy.

2.395nm UV led:

Higher brightness: Incorporating a greater amount of uv-blue visible light, the illumination range appears brighter.

Application scenarios: suitable for rapid identification, UV glue curing, outdoor lighting, or searching for large-area fluorescent traces.

Features: High cost-effectiveness, sufficient for daily household use, but background light may interfere with the detection of subtle fluorescence.

What can we do after purchasing UV flashlight ?

UV flashlights are not just for illumination; they are more often used as "inspection tools". Here are some of the most common uses in daily life:

1.Home hygiene inspection:

Pet urine: Cat and dog urine emit yellow-green fluorescence under UV light, making it easy to locate hidden stains on carpets or sofas.

Fluorescent agent investigation: When irradiating daily necessities such as clothing, sanitary napkins, and facial masks, if a bright blue fluorescence appears, it indicates that fluorescent whitening agents may have been added.

Jade artifacts: Observe the traces of glue injection, cracks, or repair points on the surface of jade. Natural jade and treated jade exhibit different fluorescence reactions.

Currency and document verification: Verify the invisible anti-counterfeiting marks on RMB, passports, or driver's licenses to quickly distinguish between genuine and counterfeit items.

Industrial leak detection: When used in conjunction with fluorescent dyes, it can detect tiny leakage points in automotive air conditioning and piping systems.

Outdoor exploration: When exposed to light at night, creatures like scorpions will emit fluorescence, making it easier to capture or avoid them.

Glue curing: used for rapid curing of UV invisible glue, nail polish glue, and other materials.
