What is the allowed output variation for replacement lamps as specified by the FDA?

The allowed output variation for replacement lamps, as specified by the FDA, is 10%. This means that when a replacement lamp is placed into a tanning bed, its output must fall within 10% of the original lamp's output. This regulation ensures that the intensity of UV radiation emitted during tanning remains consistent for user safety and effectiveness. Compliance with this standard is important because significant output variations could lead to uneven tanning results or increased risk of skin damage. Thus, maintaining a 10% variance helps manufacturers ensure consumers receive a reliable tanning experience while adhering to health standards.
