660nm and 850nm red light panels explained

Wavelength is one of the first specifications you will see when comparing red light panels. LumaDerma panels combine 660 nanometre red light and 850 nanometre near-infrared light in the same device.

What does 660nm mean?

660nm sits in the visible red portion of the light spectrum. It produces the deep red glow people normally associate with an LED red light panel.

What does 850nm mean?

850nm is near-infrared and is largely invisible to the eye. LEDs using this wavelength can appear faint or unlit even when operating normally. That visual difference does not mean the LED is faulty.

Why combine both wavelengths?

A dual-wavelength panel lets you use red and near-infrared light from one surface instead of managing separate devices. Depending on the model, controls may allow wavelengths to be used together or adjusted as part of the session setup. Always follow the instructions supplied with your device.

Wavelength is not the only useful specification

Two panels can list the same wavelengths yet feel very different in practice. Compare the panel size, LED count, beam angle, manufacturer-stated irradiance and measurement distance, control options, stand design and intended coverage. Irradiance figures are only meaningful when the distance and testing method are also stated.

Which LumaDerma format uses 660nm and 850nm?

The Radiant, Axis, Axiom, Solstice and Zenith all combine 660nm red and 850nm near-infrared light. The key difference between them is format and coverage, not the headline wavelengths.
