One question. One clear answer.

Red light therapy uses specific visible-red and near-infrared wavelengths delivered by LEDs. Research studies often investigate how light is absorbed by cells, but consumer devices are not a substitute for medical diagnosis or treatment.

Nanometers describe wavelength. 660 nm is visible red light, while 850 nm is near-infrared and mostly invisible. Device specifications should identify wavelengths separately and distinguish design targets from measured output.

Follow the instructions supplied with the specific device. Session time and frequency depend on measured output, distance, and intended routine; ALPHALUX will publish model-specific guidance only after verification.

Use the distance stated in the verified device manual. Distance changes irradiance and coverage, so a generic recommendation should not replace model-specific measurements.

Start with the area you want to position the device around, the available space, and whether you prefer wearable or panel use. Then compare verified wavelength, irradiance-at-distance, coverage, controls, warranty, and return terms.
