Different technology.
Sunlighten describes Amplify RED as full-spectrum sauna heat combined with red and near-infrared light components placed within the cabin. That is a design feature, not evidence of a specific CRPS outcome.

RED LIGHT + SAUNA CABIN / 02
Amplify RED Collection.
A sauna with integrated red and near-infrared light—not just a hotter cabin.
A full-spectrum infrared cabin collection with integrated red and near-infrared light technology marketed for light-based wellness sessions.
Fit and everyday use.
Compare two-, three- and four-person layouts, the placement of integrated light components, the door, bench and electrical needs. A capacity label alone cannot tell you whether the experience will be tolerable.
Check the exact generation.
Do not merge claims from standard Amplify and Amplify RED. Same naming family, different included light systems.
