Red vs Near Infrared Light: What's the Difference?
Red light is visible to the eye, while near-infrared light is not. Many home wellness devices combine both, as the Softlight Photobiomodulation Device does with its red and near-infrared LEDs.
The basic difference
Red and near-infrared light sit at different wavelengths on the spectrum. Red light is the part you can see as a glowing red color. Near-infrared sits just beyond it and is invisible to the human eye.
Because you cannot see near-infrared light, you cannot judge by sight whether it is on. That is a good reason to rely on the device's indicator lights and instructions instead of how bright it looks.
Why devices combine both
Many manufacturers include both LED types in one unit so users get two wavelength options without buying separate products. This keeps a routine simple and saves space.
The Softlight Photobiomodulation Device takes this approach. It is designed for home use as a wellness product, and we do not claim it treats or heals any condition. Check the product page for the specific features included.
How to choose for your needs
Think about practicality first. Do you want a single compact device, or are you comparing separate units? Consider how much space you have, how often you will use it and how easy it is to hold or position.
Read descriptions closely. If a product does not state which LEDs it uses, ask the seller before buying. Clear information is a sign of a seller you can trust.
Safety notes for both types
Even though near-infrared light is invisible, you should still avoid looking directly into the LEDs. Follow the eye protection and session length advice that comes with your device.
Because individual circumstances differ, speak with a qualified professional if you have health concerns or are unsure whether light devices suit you. A wellness device is no substitute for medical advice.
