WHAT IS THE DIFFERENCE IN BASE BEDS AND UPGRADE BEDS?
Low pressure units emit both UVA & UVB at a low energy level. Low pressure units will give more of a red tone tan, and you’ll need to maintain more often. High pressure units generate UVC, UVB, & UVA, but by means of a sophisticated filtering system, only UVA is emitted during a tanning session. It will take fewer sessions with a high pressure unit it to build a golden tan and to keep it.
