This is a new Sunlighten mPulse Empower 5-person infrared sauna. It is still in its original cartons, unopened, unassembled. I paid $14,400. Asking $6,500. We ultimately opted for a larger, custom size sauna from Sunlighten. This sauna features PulselQ™ technology for separate red light, near-, mid-, and far-infrared absorption. This model allows for deeper relaxation and faster recovery through optimized wavelength delivery.
