Are the new wolf tanning beds as good as a ruva bed?

They are actually two different type of beds. Wolf beds are more like natural sun, therefore maybe more damaging to your skin. Ruva beds are less likely to burn your skin, however, you may not get as much color from 1 session as you would in a Wolf bed. My preference is an Ultra Ruva-which will emit a small amount of both UVA and UVB ray.
