The amount of UV generated from a low-pressure lamp relies on what factor?

The correct choice is based on the understanding that the amount of ultraviolet (UV) radiation produced by a low-pressure tanning lamp is significantly influenced by the temperature within the tanning unit. As the temperature increases, the efficiency of the lamp can improve, leading to a greater output of UV rays. Efficient operation at optimal temperatures allows the phosphor coating inside the lamp to emit more UV light, which is essential for effective tanning.

While other factors such as skin type, session duration, and the type of lotion can influence tanning results and individual experiences, they do not directly affect the inherent output of UV radiation generated by the lamp itself. Understanding the mechanics of tanning lamps and their operation under varying environmental conditions is crucial for optimizing tanning sessions and ensuring safety practices in tanning facilities.
