I would think that if the output (watts/centimeter squared (someone correct me on this) were the same for EVERY wavelength (nanometer?), then the two units would produce an identical tan.

If that is correct, then a body would get the same tan from a $10,000-$15,000 VHR machine as from a $30,000 HP machine. I don't have HP, but I would doubt that this is possible. A 1000 watt lamp must output more than a 160 watt lamp!
