Calculation of profits
We do not recommend the machines type Black Care Magic 24/5 and Black Care Magnum 28/7, 32/11 and 42/18 for business purposes.
The 100W machines are not economical for business purposes, since the bronzing time is considerably longer, therefore the cost of the tube and electricity is also much higher, and the possibility of exploitation is less favourable too. The guests do not visit any more the studios provided with low-power machines.
The more machines are operating in a parlour, the better they generate each other's turnover. In a modern parlour 5 to 10 machines operate in general.
