Affordable Near Infrared and Red LED Light Therapy

True to our ferocious logo, the GembaRed Rex is the king of our GembaRed LED panel family!


  • 4 Wavelengths of Red and Near Infrared Light
  • Better reflectors for shorter treatments
  • Optimized LED layout for better light blending
  • Same lightweight and sleek design as the GembaRed Groove
  • Same low-EMF design as the GembaRed Groove

Our Rex panel is professionally verified with ultra-low flicker! Negligible flicker rate, 1.2% Flicker Percentage, and 0.002 Flicker Index. This is better than most incandescent lighting.

The GembaRed Rex takes what we have learned from our previous models to offer our optimized light therapy solution. The Rex incorporates 2 wavelengths of visible red, and 2 wavelengths of invisible near-infrared making it a very versatile photobiomodulation product.

We specifically target wavelengths of red (630nm and 660nm) and near-infrared (830nm and 850nm). This provides a broad spectrum of light that is focused in two of the most popular regions for red light therapy. We use a ratio of infrared designed to mimic the sun's output ~43%, with ours at 47%.

Our sleek and portable design remains the same, while we now incorporate a higher quality reflective surface. As your body moves closer to the panel, the reflection of light from your body back to the panel helps increase the intensity!

The Rex is one of our original models that has no switch. You can purchase a switch separately on Amazon for convenience.

I LOVE My GembaRed Rex

I love this thing. I'm a person living with chronic pain following cervical spinal surgery a few years back (as well as a shoulder injury that's impacted by the neck injury). This panel brings noticeable ease and a lessening of the pain level. It also makes the tight muscles in that area relax and open up which creates even more relief from the pain. On top of that, it helps my skin like crazy. I put the panel in front of my face and it is honestly amazing how good it feels. I don't just mean physically. And I don't even know if this is something it's supposed to do, but ten minutes with the panel on my face and my mood lifts in a pretty dramatic way. And again, I relax. And more over, I notice my skin looks younger and tighter and brighter.

And I needed a little customer service help recently and was SO knocked out by how helpful GembaRed was. Like way above and beyond.

I've looked at the specs and info about the much more expensive competitors and I truly believe GembaRed is a far superior product for far less money. And clearly, being run by good people to boot. I'm in no way incentivized to say these things. It's truly just been my honest experience. I'm a serious fan of GembaRed.

I Love My Red Light

I have been fighting body wide pain for 30 years with no answers from doctors. This has been a Godsend. Thank you

Awesome customer service

These guys are amazing. I had my old gembared NIR start flickering after years of rough usage.. i pinged the owner and emailed the CS team on how to fix it. I was surprisingly shocked that without any questions asked( i obviously shared the picture of it partially lighting up) they replaced and sent an entirely new NIR panel. I am stoked as to how truthful and helpful they are to their customers. Thanks again !!

Thank you

Gemba red light therapy has drastically changed my life.

It would be cool if I had a way to hang it. It’s weird having to try and make it stand against another object just to use. Inconvenient.
