The wavelength of red LED light typically falls within the range of 630-700 nanometers (nm).
Different types of LEDs can emit slightly different wavelengths within this range, but generally, the color "red" is associated with light in this portion of the visible spectrum. The referenced article about light-emitting diodes highlights this wavelength range for red LEDs and notes their deeper penetration into the skin compared to blue LEDs.
| Color | Wavelength (nm) |
|---|---|
| Red | 630-700 |
This wavelength range is important for applications like phototherapy, where red light is used for its ability to penetrate deeper into the skin and stimulate cellular processes.
