When comparing two red light therapy beds that look similar, you might be wondering why one is cheaper while the other is more expensive. The difference lies in the internal components and engineering.
- LED Count and Density: More LEDs generally mean more uniform coverage, but the quality of the diodes matters more than the quantity.
- 放射照度 (電力出力): Higher irradiance allows for shorter session times while still delivering an effective dose of light energy.
- Wavelength Precision: High-end manufacturers use diodes with very narrow tolerances to ensure the light is exactly at the therapeutic peak.
- Cooling and Thermal Management: LEDs generate heat. Professional beds require sophisticated internal cooling to prevent the diodes from degrading and to keep the user comfortable.
- EMF Shielding: Premium beds are engineered to have low or zero electromagnetic field (電磁波) emissions, which is a priority for health-conscious users.
- Warranty and Support: A More Expensive bed usually comes with on-site installation, training, and a multi-year comprehensive warranty.
