What are UV Lamps?

Ultraviolet (UV) lamps are specialized light sources that emit UV radiation, a form of electromagnetic energy with wavelengths shorter than visible light but longer than X-rays. These lamps are widely used in industries ranging from healthcare to manufacturing due to their ability to disinfect, cure materials, and initiate chemical reactions. UV lamps come in various types, including low-pressure, medium-pressure, and LED-based models, each tailored for specific applications.
