1. To distinguish the quality of UV flashlights, you can evaluate them from the following aspects:

UV Wavelength: A quality UV flashlight will usually provide the correct wavelength range. In the ultraviolet spectrum, UVA (near ultraviolet) has a wavelength of 315-400 nanometers, UVB (mid-ultraviolet) has a wavelength of 280-315 nanometers, and UVC (far ultraviolet) has a wavelength of 100-280 nanometers. A good flashlight should be able to emit exactly the desired UV wavelength.

Light source quality: Light source is one of the key factors in judging the quality of a flashlight. High-quality UV flashlights usually use high-quality UV LEDs as light sources, which have a longer service life and more stable output. In contrast, low-quality flashlights may use cheap UV fluorescent lamps or LEDs with inaccurate or unstable wavelengths.

Functions and features: A good UV flashlight should have some functions and features, such as adjustable light intensity, waterproof and shockproof design, portability, etc. In addition, some high-end products may also have additional features, such as UV filters, multiple working modes, etc.

Product reviews and word-of-mouth: Before purchasing, you can check reviews and feedback from other users to understand the performance and quality of the product. Relevant information can be obtained through channels such as online shopping platforms, forums or social media.

2. There are many ways to identify the quality of UV flashlights. The following are some common methods:

Observe the appearance of the UV flashlight to see if there are any obvious scratches, deformations, etc.

Check the lens of the UV flashlight to see if there are cracks, bubbles, etc.

Use a UV flashlight to illuminate banknotes and other items to see if you can see a fluorescent reaction. If you can see the fluorescence reaction, it means the UV flashlight is of good quality.

Use a UV flashlight to shine on the black paper to see if you can see the white lines on the black paper. If you can see the white line, it means the UV flashlight has a shorter wavelength and higher power.

All in all, a high-quality UV flashlight should have the correct wavelength range, use a high-quality light source, have the necessary functions and features, and have good user reviews.
