More Red Light Isn't Better. Here's The Number That Actually Matters.
You bought the panel. You stand in front of it. But you have no idea if you're hitting the right dose, or blowing past it. Most people aren't. Here's the one variable that decides everything.
How To Dose Red Light Therapy
Dose is energy delivered, not time spent.
Restore Red Light is built for recovery routines, and dose is the setting you control. The problem is almost nobody measures dose correctly. They measure minutes.
Dose is energy per area, measured in joules per square centimeter (J/cm²). It's set by three things: how much power your panel puts out (irradiance, in mW/cm²), how long you're exposed, and how far you stand. Change any one and you change the dose. Stand twice as far and the energy hitting you drops sharply, distance is the variable people get most wrong.
Irradiance is how much light energy lands on a surface, measured in mW/cm². It's the panel's raw output at a given distance. Restore Red Light panels deliver professional-grade irradiance, but irradiance alone isn't dose. It's one of three inputs that combine to produce the number that matters.
Dose accumulates over time. Irradiance multiplied by seconds of exposure gives you total energy delivered. This is why "just stand there longer" feels intuitive, but it's also the trap. Time pushes you up the curve, and the curve doesn't keep climbing.
Light intensity falls off fast as you move away from the source. A panel that's powerful at 6 inches delivers a fraction of that at 18 inches. Most people stand too far back and never reach the window. Distance is the single biggest reason home users under-dose without knowing it. The same arithmetic decides equipment: if you are specifying a commercial red light panel for a med-spa or esthetics studio, irradiance quoted at the distance a client actually sits is the number that sets the dose.
Dose has a window. Too little and you're under-dosed. Inside the window, you're dialed in. Past it, more time is just more time. This is the rule that separates people who dose on purpose from people who just stand in front of a light.
Red light (around 630 to 670nm) stays shallow. Near-infrared (810nm and up) reaches deeper. Restore Red Light panels run both. One rule that's locked at RECON: skip near-infrared within 90 minutes of bed and use 660nm red only.
The Dose Curve
Find where you land. The goal isn't the far right, it's the peak.
Move the sliders. Watch where your dose lands on the curve. The goal isn't the far right, it's the peak. Drag too far and you'll watch the dose slide past the window.
This is surface dose, energy landing on your skin. Less reaches the muscle and joint underneath, because skin and fat scatter light on the way down. That's why surface targets like skin sit comfortably in a wide window, while deep tissue needs a higher surface dose to deliver enough below. The higher your panel's output, the faster you reach the window, so time is the lever you pull to stay in it. Illustrative model based on professional-grade output (~160 mW/cm² at 6 in); real dose varies by panel, distance, body area, and skin. The point isn't the exact number, it's the shape of the curve.
Red Light Therapy Wavelengths Explained
Eight wavelengths. Eight jobs.
Dose tells you how much energy you're delivering. Wavelength tells you where it goes. Red light stays shallow. Near-infrared reaches deeper. They aren't competitors, they're different tools for different depths, and Restore panels run both.
This is why most Restore Red Light presets fire all eight wavelengths at once. It isn't about cranking intensity, that's the dose curve, and you can overshoot it. Spectrum is different. Running all eight puts the surface bands and the deep bands in one session, red through near-infrared, at the same time.
Bare Skin And Red Light Therapy
Skin prep decides how much light actually gets in.
You dialed the distance. You set the time. Then you blocked half the dose with a barrier you didn't think about. Light has to reach bare skin, and what's on your skin, or covering it, decides how much actually lands. This costs nothing and most people get it wrong.
Under-Dosing vs. Over-Dosing Red Light
Under. Dialed. Over. Only one hits the window.
Everyone using red light at home is doing one of three things. Only one of them lands in the window. Find yourself here.
Standing too far back. Two-minute sessions. A panel that's too small for the body area. You feel responsible, you're "doing red light", but you never reach the starting window. This is the most common failure, and it's invisible. Nothing tells you you're short of the window.
Right distance. Right duration for the target tissue. The dose lands in the window. This isn't luck, it's understanding the three inputs and hitting the peak of the curve on purpose.
"If ten minutes is good, thirty is better." Not here. Past the window, extra minutes don't make it a better session. You're not being thorough, you're just standing there longer.
Red Light Therapy Dose By Goal
Starting points you can dial from, not prescriptions.
Starting references for a professional-grade Restore Red Light panel. RECON's starting surface window for most recovery routines is roughly 20 to 60 J/cm², which a ~160 mW/cm² panel reaches fast up close. Adjust to your panel and how sessions feel. These are recovery routine starting points, not medical prescriptions.
| Distance | Time | Target | Cadence |
|---|---|---|---|
| 6 in | 3 to 6 min | ~30 to 60 J/cm² | 4 to 5×/week |
| 12 in | 10 to 20 min | ~25 to 50 J/cm² | 4 to 5×/week |
Muscle sessions are dosed in total joules per muscle group, not surface J/cm². Larger areas need more total energy. Field-standard targets:
| Muscle Group | Total Dose | Timing |
|---|---|---|
| Large (quads, hamstrings) | 60 to 300 J | Pre or post-training |
| Small (biceps, calves) | 20 to 60 J | Pre or post-training |
| Distance | Time | Window |
|---|---|---|
| 6 to 12 in | 10 to 15 min | >90 min before bed |
These are starting settings: 20 to 60 J/cm² at the surface, and 60 to 300 J (large) or 20 to 60 J (small) total per muscle group. RECON keeps its dose numbers specific, not round numbers that sound good.
Red Light Is One Pillar Of Three
Recovery is a system, not a single light.
660 nm red and 850 nm near infrared are absorbed by cytochrome c oxidase, an enzyme in the mitochondria. But recovery is a system. RECON builds it across three pillars: compression, PEMF and red light.
Restore Red Light Panel
8 wavelengths (630, 650, 660, 670, 810, 830, 850, 1060nm) on a dual-chip LED array. The dose math above assumes this kind of output.

Restore Red Light panels are built for professional-grade output, so you can actually reach the window instead of standing in front of a glow and hoping.
