When you expose bacteria to 365 nanometer light, it causes damage to the DNA inside the cells. This damages the DNA, which prevents cells from functioning properly. Eventually, the cells die and the bacteria no longer exist.

When you are not sure whether the food has gone bad, you can see the difference in the food by irradiating with 365nm UV light.

202368 — I've written a tutorial for controlling lighting in your images. https://stable-diffusion-art.com/control-lighting/ Hope someone would find this useful!

When choosing a UV torch light, it is important to consider the application you will be using it for. If you are looking for the most common type of UV torch, then a 365nm UV torch light is likely the best option.

Finally, it is important to consider the quality of the torch light when making your selection. Look for one that is made of durable materials and has a reliable power source. Make sure the torch light is within your budget.

In June 2023, Olight released the most powerful UV torch, the Seeker 4 Mini 2-in-1 torch with both white and UV light (760MW of UV light), check it out!

From the above table, you can see that ultraviolet rays are divided into different types of ultraviolet rays according to their wavelengths, including UVA, UVB, UVC, near ultraviolet, and far ultraviolet.

Blacklight, also known as long-wave ultraviolet light, has a wavelength between 400 and 315 nanometers (nm). It is a type of ultraviolet light (UVA light) that emits ultraviolet radiation in the UVA band. These ultraviolet rays have low energy and long wavelengths, and the ultraviolet radiation (radiation to the human body) is also minimal.

The LED Light 9R Power Adaptor is an essential accessory designed to provide reliable and efficient power for your LED lighting systems.

Illuminance is the transmission of natural light (windows, lighting plates... ). Lighting is the distribution of artificial light (Lamp, floor lamp, neon.

The new product Arkfeld UV LED Torch released in March 2023 has both UV light and LED light, dual light source lighting.

365nm UV light (also referred to as "long wave UV light", "black light") is a type of near-ultraviolet light that is invisible to the naked eye. It is often used in special lighting applications and is particularly well-suited for fluorescence and bacterial detection. With a longer wavelength than the short-wave visible light, it is able to penetrate substances more deeply and thus provide a deeper illumination.

2. It is also used in counterfeit detection, such as in currency and document authentication, as well as in material testing and research.

It can also be used in science and industry, such as in counterfeit detection, material testing, and medical diagnostics. 365nm UV light is used to detect minute differences in materials which could not be revealed through visible light. Because of its ability to penetrate deeply, it is also useful for studying the structure of objects or materials which may require very detailed imaging or measuring.

1. It is used by forensic scientists and law enforcement personnel to detect evidence of past events which can't be seen using visible light.

Because of the nature of the longer wavelength, substances which may be difficult to detect with a shorter wavelength of visible light can be easily revealed with 365nm UV light. This means that it can be used to reveal evidence of past events which may have otherwise been impossible to detect. Examples include traces of fingerprints on surfaces and documents, biological matter like saliva, and other types of evidence that are often seen in criminal investigations.

It is also important to select a torch light with the proper voltage. A lower voltage is better for counterfeit detection because it produces less heat, making it easier to detect subtle differences in materials. Higher voltages, however, produce a brighter light and are better suited for entertainment and other purposes.

3. Manufacturers use 365nm UV light to examine materials for defects, irregularities, or inconsistencies that may be difficult to detect with visible light.

Medical professionals and domestic use 365nm UV light to look for evidence of disease, fungi, and bacteria which can be illuminated under this wavelength. In some cases, it can be used to detect the presence of harmful molds which cannot be seen with the naked eye.

One benefit is that it is able to penetrate deeper than visible light and thus provide a deeper illumination. This makes it useful for detecting evidence of past events and other materials which may be difficult to discern with visible light. It is also safer to use than short-wave UV light due to its lower intensity.

Another benefit of black light is that it is often used to detect counterfeit currency and documents. The unique wavelength of black light is able to reveal details which may be otherwise impossible to detect with the naked eye.

2023216 — It aids in the temperature regulation of LEDs and avoids overheating. That is why an LED heat sink is vital to any LED lighting system. The heat ...

Short-wave UV, germicidal UV, ionizing radiation at shorter wavelengths, completely absorbed by the ozone layer and atmosphere: hard UV.

Therefore black light is used in many of the same applications as 365nm UV light, such as counterfeit detection and fluorescence.
