How Does Red Light Therapy Work?
Red light therapy, also called photobiomodulation, delivers red and near-infrared light to the body. Wavelengths between 630 and 680 nm (red) and 800 and 1070 nm (near-infrared) are the most widely researched for supporting mitochondrial activity and cellular energy production, the part of the cell that creates sustainable energy.

Red and near-infrared: what each does
- Red light (about 630–680 nm) works at the surface and in shallower tissue.
- Near-infrared (about 800–1070 nm) reaches deeper tissue. 810 nm is the deepest-penetrating of the well-studied wavelengths.
- The wavelengths with the most research are 630, 660, 810, 830 and 850 nm. 660 and 850 are perhaps the most widely used.
- The Trifecta Light PRO 450 emits four wavelengths from about 630 to 940 nm, two red and two near-infrared, for layered photobiomodulation of surface and deeper tissue.
Intensity and dose
Irradiance is how strong the light is, measured in mW/cm². Research suggests the most biologically appropriate range falls between 20 and 40 mW/cm². The PRO 450 delivers up to 150 mW/cm² at the surface, with fully adjustable output so it can run in that range.
More is not always better. Studies show a biphasic dose response: too little light is ineffective and too much can reduce benefits. For whole-body beds in research-supported ranges, sessions typically fall between 10 and 20 minutes. The PRO 450’s therapeutic dose is a 10 to 12-minute session.
Why full body, front and back
Panels treat one area at a time and must be repositioned, which can create uneven dosing and longer sessions. A full-body bed surrounds the user with light. The PRO 450’s 5,016 LEDs above and below treat the front and back together, so the client never has to turn over.
Why lights alone
Adding vibration, PEMF or heat to a red light bed can bring more blood to the surface. Hemoglobin absorbs red and near-infrared light, potentially reducing how much light reaches deeper tissue. That’s why the PRO 450 delivers light alone; other therapies should be used afterwards.
What it’s used for
The Trifecta Light PRO 450 is FDA cleared for fat loss and healing: non-invasive fat and circumferential reduction, and whole-body therapy for pain management, muscles, joints and injuries. Providers describe the wellness benefits as more energy, more clarity, better sleep, better skin, reduced pain and faster recovery.
Questions
Is red light therapy the same as infrared?
No. Red light is visible (about 630–680 nm). Near-infrared is invisible and reaches deeper (about 800–1070 nm). The PRO 450 combines both.
How long is a red light therapy session?
On the PRO 450, 10 to 12 minutes. Whole-body beds in research-supported ranges typically run 10 to 20 minutes.
Is the Trifecta Light bed FDA cleared?
Yes. The PRO 450 is the only full-body red light therapy bed FDA cleared for both fat loss and healing.
