Not getting your question. I used to own a tanning salon... what do you want to know?
All tanning beds are based on the amount of bulbs they hold (mine had 35 each... giving a good overall surround). The BULBS tan people... not the beds. The quality of the bulbs depends on the manufacturer.... back when I had my shop they were $40 each.... to replace the bulbs in just one bed was very expensive.... but without bulbs in good condition, you'd lose customers....
The tanning business for an average sized shop costs upwards of $10 thousand a month to run. Not for the faint of heart.
