Differences between UVA, UVB and UVC lamps.

Ultraviolet lamps (UV lamps) are divided into three main types depending on the wavelength of the ultraviolet light emitted: UVA, UVB and UVC. Here are their main differences:

  1. UVA (320-400 nm) :
    • UVA lamps have the longest wavelength of the three types, ranging from 320 to 400 nm.
    • This type of ultraviolet radiation penetrates deep into the skin and can cause photoallergic and phototoxic reactions.
    • UVA rays play a key role in skin aging and the development of skin cancer.
  2. UV-B (280-320 nm) :
    • UVB lamps have a medium wavelength, from 280 to 320 nm.
    • This type of ultraviolet radiation can cause sunburn and is involved in the development of skin cancer.
    • UVB rays affect the upper layers of the skin and promote the formation of vitamin D.
  3. UF-S (100-280 nm) :
    • UV-C lamps have the shortest wavelength of the three types, ranging from 100 to 280 nm.
    • This type of ultraviolet radiation has the highest energy and has a strong bactericidal and viricidal effect.
    • UV-C rays are almost completely absorbed by the Earth’s atmosphere and do not pose a danger to humans under normal conditions.

The use of each type of UV lamp depends on the specific purposes and requirements of the application, whether it is cosmetic, medical, industrial or scientific research. It is important to choose the right type of lamp and take appropriate safety precautions when working with them, especially when it comes to UVA and UVB radiation, which can be harmful to health if used incorrectly.
