Sauna Heater Size & kW Calculator
Accurate sizing is critical for safety and performance. Use our Sauna Heater Sizer to determine the required Kilowatts based on your width, depth, and height, adjusted for glass and stone heat loss as well as internal or external factors. Guaranteed to deliver 175F in under 45 minutes.
Red light therapy panels deliver targeted wavelengths of light to the skin and tissue to support recovery, skin health and cellular energy — without the heat of a sauna. Unlike infrared heating panels, these are not designed to warm a room or make you sweat; they emit specific red and near-infrared wavelengths from high-output LED arrays, dosed by time and distance rather than temperature. Our collection focuses on clinically-relevant wavelengths, high irradiance for shorter sessions, and low-EMF, low-flicker builds suitable for daily home use.
- Clinically-Relevant Wavelengths: We prioritise panels emitting red light at 630 to 660nm for surface skin and collagen, and near-infrared at 810 to 850nm for deeper tissue and muscle recovery.
- High Irradiance Output: We focus on panels with strong measured irradiance (mW/cm²), which determines how short and effective each session is at a given distance.
- Full-Body or Targeted Coverage: We offer both compact panels for spot treatment (face, joints) and full-length towers designed to treat the whole body at once.
- Low-EMF & Low-Flicker: We select panels engineered for minimal EMF at treatment distance and flicker-free operation for comfortable, repeated daily use.
Most Asked Questions About Red Light Therapy Panels
Getting results from red light therapy comes down to wavelength, dose and distance. We've put together these answers to help you choose and use a panel correctly.
What's the difference between red light and near-infrared?
Red light (around 630 to 660nm) is absorbed near the skin's surface and is used for skin tone, collagen and complexion. Near-infrared (around 810 to 850nm) is invisible and penetrates deeper, supporting muscle recovery, joints and circulation. Many panels combine both.
What wavelengths should I look for?
The most researched wavelengths are 660nm (red) and 850nm (near-infrared). A panel offering both covers the widest range of goals, from skin health to deep-tissue recovery.
How long should a session be, and how often?
Most sessions run 10 to 20 minutes per area, used daily or several times a week. Exact timing depends on the panel's irradiance and your distance from it — higher output means shorter sessions.
How far should I sit from the panel?
Typically 6 to 18 inches, depending on the panel. Closer gives a stronger dose in less time; further covers more of the body but needs a longer session. Follow the manufacturer's guidance for that specific panel.
What is irradiance and why does it matter?
Irradiance (measured in mW/cm²) is how much light energy reaches your body at a given distance. It's the single most useful spec — it determines your dose and therefore how long each session needs to be.
Do I need eye protection?
The light is bright but not UV. Goggles aren't strictly required, but many people prefer to close their eyes or wear the goggles supplied for comfort during facial treatments.
Is red light therapy the same as an infrared sauna?
No. An infrared sauna uses heat to warm the body and induce sweating. Red light therapy uses specific light wavelengths at normal room temperature — no heat, no sweat — to stimulate cellular activity.
What are the main benefits?
Reported uses include skin tone and collagen support, faster muscle and joint recovery, reduced soreness, and improved circulation. Results build with consistent regular use rather than a single session.
Is it safe to use every day?
Yes. Red light therapy is non-invasive and generally considered safe for daily use. Consistency tends to matter more than long individual sessions.
Does it heat the room or make me sweat?
No. These panels emit light, not meaningful heat, so they won't warm a room or raise your body temperature the way a sauna heater does.
Can I use red light therapy alongside a sauna?
Yes. Many people pair the two — the sauna for heat and cardiovascular benefit, red light for targeted skin and recovery support. They're complementary, not interchangeable.
