Ultraviolet (UV) radiation is a type of electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. UV radiation can be further subdivided into three categories based on its wavelength - UVA, UVB, and UVC. UV lamps are sources that emit UV radiation in one or more of these bands to carry out important applications.

Uses of UVA (315-400 nm)
UV Lamps have the longest wavelengths within the UV spectrum and possess low energy. They are not considered carcinogenic but can cause cumulative damage to skin over time with prolonged exposure. UVA lamps are commonly utilized for curing and drying applications in industries like printing, painting, manufacturing etc. The long wavelengths allow UVA to effectively penetrate surfaces and initiate photochemical reactions to solidify or dry coatings. Artificial UV sources are also employed in reptile habitats to provide the full UV spectrum necessary for calcium metabolism and other physiological processes in cold-blooded pets.
