UV 12W 365nm has become a popular term in the industry, referring to a specific type of ultraviolet (UV) light source that emits light at a wavelength of 365 nanometers with a power output of 12 watts. This type of UV light is widely used in various applications, from curing inks and coatings to sterilization and disinfection. In this article, we will delve into the details of UV 12W 365nm, exploring its characteristics, applications, and the technology behind it.

Introduction to UV Light and its Wavelengths

Ultraviolet (UV) light is a form of electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. The UV spectrum is divided into three main categories: UVA, UVB, and UVC, with wavelengths ranging from 400 to 10 nanometers. UV 365nm falls within the UVC range, which is known for its germicidal properties and ability to penetrate and damage the DNA of microorganisms.
