What is the output percentage of UVA from high-pressure tanning equipment?

High-pressure tanning equipment is designed to specifically emit a significant amount of ultraviolet A (UVA) radiation, which is crucial for achieving a deep and long-lasting tan. The output percentage of UVA from these machines typically reaches around 99%. This is primarily because high-pressure tanning beds utilize specialized bulbs that focus on producing UVA rays, as these wavelengths penetrate the skin more deeply than ultraviolet B (UVB) rays and stimulate the production of melanin, the pigment responsible for tanning.

In contrast, other types of tanning beds—such as low-pressure ones—have a lower percentage of UVA output, often including more UVB rays. The higher UVA output in high-pressure tanning equipment is what differentiates it from other forms of tanning and is an essential aspect of its effectiveness for those seeking a tan. This high percentage of UVA is why users experience faster results, as UVA is the dominant type of radiation in these machines, allowing for efficient tanning while minimizing the risk of UVB-related skin damage often associated with excessive exposure.
