Chippp, none of the items you mentioned determine actual session lengths as determined by manufacturers. Let's go through it with actual examples:1. I have a Tan Amercia 32 with 6.5 reflector lamps. Maximum labelled session is 20 minutes. Lamps are very close. It reddens up nearly everyone including veteran tanners. I would estimate the MED at about 5 minutes for skin type 2. That would mean a 20 minute maximum session. In the next room I have a 1992 Sundash unit, 32 lamps with Bellarium S OEM lamp. I would estimate the MED on this unit at about 9 minutes. That's a maximum 36 minute session--but both units have identical labels. Other examples abound and verticles are not exempt from these anomalies. You don't see the extremes with stand-ups becasue who wants to stand for 17 minutes? That's the ONLY reason.2. In the marketplace, the number of lamps makes no difference in determining exposure times. You can buy a home ETS machine with 16 lamps with Diamond Sun S lamps with a 20 minute timer and you can buy a 36 lamp ETS bed with the same or similar lamps with the same 20 minute exposure.3. Distance from the user makes no difference. The Mega-Sun VHR beds have a 20 minute timer and practically sit on your nose. Pro-Sun Lumina uses the same VHRs with the lamps about a foot form your face. Expousre time=15 minutes.It's all marketing you see, not science. They just want you to think so. In truth, bed manufacturers think the FDA and salon owners are idiots who won't notice. If enough salon owners expressed enough outrage, they might change their ways. Until then, the label on your tanning equipment is misleading at best, a dangerous lie at worst.
