I use these beds as my entry levels and run my EFT on them. They have genesis 120 + 11 facials in each. 15 min. tan time. Wanted to know if these beds could be cut down to a 10 min. tan using a stronger lamp so they can get faster results to compensate for cutting the tan time down. When season comes I can move more traffic in and out. This is the reason for doing this if possible since so many have that membership. What lamps would you recommend?
