Lets talk 850nm vs 940nm…
Not all near-infrared wavelengths interact with the body’s tissues the same. The larger number doesn’t mean the light is “stronger.” It simply means it’s a different “color,” and reacts with tissue in a different way.
Research has found that the 850nm wavelength is capable of penetrating deeper into soft tissue than 940nm. This is one reason it is called the “Gold Standard” of infrared therapy.
This is because 940nm light is more readily absorbed by water within the tissues, which limits how deeply the light can travel. In contrast, 850nm wavelengths are able to pe*****te more effectively - up to 30% deeper- into deeper muscles, tendons, joints, and soft tissues.
Further, 850nm is superior to 940nm in stimulating the mitochondria, an essential step in producing ATP and speeding the recovery process at the cellular level.
These distinctions are especially important in horses. Large muscle groups and dense soft tissue structures require wavelengths capable of reaching as deeply as possible, and to produce meaningful cellular activity where recovery is critical.
This is exactly why every Redline product combines:
• 660nm red light for surface-level cellular support
• 850nm near-infrared light for deeper tissue pe*******on
Wavelength selection was one of the most intentional parts of designing Redline because effective light therapy is about more than simply using red light, it’s about using the right wavelengths for the job.
