We have 2 different infrared sauna types here.
Pink room is a Sunlighten mPulse sauna that has full spectrum of infrared and can be programmed for very specific spectrums for detox, pain relief, cardiovascular benefits and more. It does NOT tend to run as hot (135-144).
Green room (and BLUE room next door) is a Sunlighten Amplify II sauna that has full spectrum but rolls through all the wavelengths as if on a "scan" setting of a radio. You get all the benefits but it is less specific. It has higher heat capability than the pink room (145-165).
