Product Background
A Pictorial History of Light (Photobiomodulation) Therapy
In the past, light therapy was conducted like this.
Auguste Rollier & Heliotherapy in Europe
Health Management Using Sunlight (1936)
Tuberculosis Treatment Using Sunlight
Rollier said that exposure to the sun at temperatures above 18°C is not “sunbathing” but “air bathing.”
However, this method had many issues due to ultraviolet exposure.

Incandescent bulbs can function as a sauna, but they cannot precisely apply the correct wavelength (First Law of Photobiology) or intensity (Second Law of Photobiology) to target cells or chromophores for therapeutic purposes.

| Features | The heat device using incandescent bulbs (halogen lamps) functions as a sauna. In other words, it cannot precisely apply the correct wavelength (First Law of Photobiology) or intensity (Second Law of Photobiology) to target cells or chromophores. |
| Near-Infrared Wavelength | Weak near-infrared output with therapeutic effects, high heat sensation. |
| Cost | High electricity cost. *Requires connection to plumbing, and artificial cooling with flowing water, leading to necessary sewage construction. Halogen lamps have a short lifespan, requiring full replacement every 10 months. |
| Maintenance Cost | Very high |
| Usage Time | Over 1 hour |
