KNOW THE LIGHT
The Redwell Guide.
Clear answers on how Redwell works, how to use it, and which panel fits you.
Redwell answers common questions about red light therapy, 630 nm, 660 nm, 810 nm and 850 nm wavelengths, power, treatment distance, session time and choosing the right panel.
A focused spectrum.
Two red wavelengths. Two near-infrared wavelengths. Selected for the way Redwell is designed to be used.
Surface-focused red light suited to skincare and everyday wellbeing routines.
A core red wavelength widely used across photobiomodulation.
Beyond visible light, with deeper penetration characteristics than red light.
A widely used NIR wavelength for recovery routines and larger treatment areas.
THE REDWELL APPROACH
Focus on what matters.
Judge a panel by the light it delivers: useful output, even coverage and a practical dose.

WAVELENGTHS & POWER
Understand what actually matters when comparing wavelengths, output and power.
What is the difference between 630, 660, 810 and 850 nm?
630 and 660 nm are visible red wavelengths. 810 and 850 nm sit in the near-infrared spectrum.
They have different absorption and penetration characteristics, which is why Redwell combines both red and NIR rather than relying on a single wavelength.
Why does Redwell focus on four wavelengths?
Because focus lets us put the panel's optical output where it matters. Redwell's core spectrum combines 630 + 660 nm red light with 810 + 850 nm near-infrared, giving a deliberate spread from surface-focused to deeper-reaching light.
Instead of stretching the spectrum across a longer list, Redwell keeps those four wavelengths concentrated and balanced across the panel.
Four is not a compromise. It is the design.
Why is Redwell built around red + near-infrared?
Because red + near-infrared gives Redwell the range we want across skin, movement, recovery and larger-body routines.
Red light works closer to the surface, while near-infrared reaches deeper. Together, they create a simple spectrum with a clear role from one wavelength to the next.
Blue light can be useful in specific skincare applications, but it is a different tool for a different job.
Why do some LEDs look like they are not illuminated?
810 and 850 nm are near-infrared wavelengths and sit largely outside human vision.
That means some LEDs may look dim or almost unlit even while they are operating normally.
What is irradiance, and why does it matter more than wattage alone?
Irradiance describes light power reaching a given area, usually expressed in mW/cm².
Electrical wattage tells you how much power a device consumes. Irradiance is more useful for understanding the light actually reaching the treatment area.
How does wavelength count affect output?
A panel has a fixed amount of light output to work with. Add more wavelengths without adding more emitters or power, and that output has to be shared across more channels.
Redwell keeps its core output concentrated across 630, 660, 810 and 850 nm, so those wavelengths can be delivered strongly and evenly across the panel.
USING REDWELL
Distance, timing and how to build Redwell into a practical routine.
How far should I be from the panel?
Around 15–30 cm is a practical starting range for many routines. Follow the guidance for your specific model because panel size and output vary.
How long should a Redwell session be?
For many routines, 10–15 minutes per area is a sensible starting point. Making a session longer does not automatically make it better.
Can I use Redwell every day?
Many people build Redwell into a regular routine. If you are new, starting around 3–5 times per week and adjusting based on your device guidance is a sensible approach.
Does the light need direct contact with bare skin?
For the most direct and consistent exposure, keep the treatment area free from thick clothing or materials that block the light.
Should I use serum or skincare before Redwell?
For a simple, consistent routine, we recommend starting with clean, dry skin and applying your normal skincare afterwards.
Is morning or evening better?
The best time is the time you can maintain consistently. Many people use Redwell in the morning around movement or in the evening as part of a slower wind-down routine.
SAFETY & COMFORT
Common questions for using Redwell comfortably and confidently.
Do I need to wear eye protection?
Redwell panels are very bright. We recommend using the supplied eyewear, particularly for facial or close-range sessions or whenever the brightness feels uncomfortable.
Does Redwell emit UV?
No. Core Redwell panels use red and near-infrared light, not ultraviolet light.
What if I am pregnant or take photosensitising medication?
If you are pregnant, have a condition requiring medical supervision, have an eye condition or take medication that increases light sensitivity, speak with your doctor or healthcare professional before use.
Does Redwell heat the skin?
You may feel some warmth when close to a panel, but Redwell is not a sauna or heat therapy device. If it becomes too warm or uncomfortable, increase your distance or stop the session.
CHOOSING YOUR REDWELL
Choose the right model for your coverage, space and frequency of use.
How do I know which Redwell panel is right for me?
Start with the area you want to cover, your available space and how often you plan to use it. Smaller panels suit targeted routines. Larger panels give greater coverage and make whole-body or professional use easier.
What is the difference between SmartGlow and Glow?
SmartGlow is compact and ideal for facial or targeted use. Glow gives you more coverage for areas such as the back, legs and joints.
When should I choose GlowPro instead of Glow?
GlowPro makes sense when you want greater coverage, more frequent use or a more professional setup. It is also a popular choice for studios, gyms and recovery spaces.
Who is GlowPro Plus designed for?
GlowPro Plus is designed for users wanting wider coverage and a more advanced professional experience within a compact footprint.
Who should choose GlowPro Max?
GlowPro Max is our full-body option for spaces wanting a standout Redwell experience: resorts, spas, gyms, clinics, recovery studios and other professional environments.
