Question: what is the difference between a level 3 and level 4 tanning bed?
Answer: Level 3 offers medium pressure lamps with lower UV rays and more UVA rays, providing a faster and deeper tan than Level 1 and Level 2. And finally Level 4 tanning beds (and up) feature ridiculously fast tanning times, with sometimes next to zero UVB rays, guaranteeing a dark tan with virtually no chance of a sunburn.
