Adding red light therapy to a sauna can combine two different wellness experiences in one space: light exposure from specific red and near-infrared wavelengths, and heat exposure from the sauna itself. But a standard indoor red light panel should not simply be carried into a hot sauna.
The panel needs to be specifically built and rated for sustained heat and humidity. It also needs secure mounting, adequate airflow, safe power routing, and enough room for you to sit or stand at a useful distance.
This guide explains how to add red light therapy to a traditional or infrared sauna safely. It also compares the compact Hooga Ember and full-size Hooga Blaze so you can choose the right coverage for your space.
Can you put a red light therapy panel in a sauna?
Yes, but only when the panel manufacturer specifically rates the device for use inside a sauna.
Most conventional red light therapy panels are designed for normal indoor temperatures. Sauna conditions introduce sustained heat, humidity, and possible water exposure that can damage housings, electronics, power supplies, adhesives, and connections that were never engineered for that environment.
A sauna-compatible panel should have documented operating-temperature and ingress-protection ratings. Those ratings should come from the manufacturer rather than an installer’s assumption or a product’s outward appearance.
The Hooga Sauna Series uses an IP65-sealed aluminum housing, an IP65-rated internal driver, active cooling, and an automatic temperature-protection system. Both Ember and Blaze are rated to operate at temperatures up to 194°F / 90°C. If the panel’s internal temperature rises above that limit, the system automatically shuts the panel down and restarts after the internal temperature falls below 140°F / 60°C.
IP65 does not mean the panel is submersible. Do not immerse a panel, place it in a steam room unless the manufacturer expressly allows it, or clean it with high-pressure water. Refer to the Hooga Sauna Series User Manual for complete operating and installation requirements.
Red light therapy and infrared saunas are not the same thing
The terms “red light,” “near-infrared,” and “infrared sauna” are often used as though they describe one treatment. They do not.
Red light therapy uses targeted wavelengths of visible red and near-infrared light. Hooga Sauna Series panels use 630 and 660 nanometer red light plus 810 and 850 nanometer near-infrared light.
An infrared sauna is designed primarily to create heat. Its infrared emitters warm the body and sauna environment, but that does not mean the sauna is delivering the same wavelengths, intensity, or light exposure as a purpose-built red light therapy panel. Likewise, the red glow from a heater or sauna lamp is not proof that it is providing red light therapy.
The two technologies can be used in the same routine, but they perform different jobs. For a deeper explanation, read Red Light Therapy vs. Saunas and Red Light vs. Near-Infrared vs. Infrared.
What makes a red light panel sauna-safe?
Do not judge sauna compatibility by whether a panel has a metal case or cooling fans. Look for explicit manufacturer specifications covering the environment in which it will operate.
Documented operating temperature
The panel should have a published maximum operating temperature that covers the conditions inside your sauna. The rating should apply to active operation, not just storage or shipping.
Protection from dust and water
An ingress-protection rating describes how an enclosure resists solid particles and water. Ember and Blaze carry an IP65 rating, which means their enclosures are dust-tight and protected against water jets. It does not mean they can be submerged.
Heat-appropriate housing and internal components
The enclosure, driver, wiring, seals, and cooling system all need to tolerate the rated environment. A standard panel may contain plastics, adhesives, connectors, or power components intended only for room-temperature use.
Automatic thermal protection
A thermal shutdown system gives the panel a defined response if its internal temperature exceeds the operating ceiling. This is an important safeguard, but it does not replace correct placement, clearance, or installation.
Clear installation instructions
The manufacturer should explain mounting, airflow, power routing, treatment distance, and cleaning. If the instructions do not explicitly permit sauna use, assume the device belongs outside the sauna.
How to add red light therapy to a sauna
Measure the usable installation area
Measure the open wall height, width, and depth before choosing a panel. Account for benches, doors, heater clearance, control panels, and the position your body will occupy during a normal session.
Ember and Blaze are both 12 inches wide and 2.2 inches deep. Ember is 20.1 inches tall, while Blaze is 36.6 inches tall. The additional height gives Blaze a larger treatment area without requiring a wider section of wall.
Keep the panel away from the heater
Do not mount the red light panel directly above the sauna heater or in the hottest concentrated zone of the cabin. Follow all clearance requirements for both the sauna heater and the light panel.
The Sauna Series manual calls for at least four inches of open space around the panel so air can circulate. Do not block the vents with towels, backrests, trim, or other accessories.
Plan the treatment position
Install the panel based on where your body will be while seated or standing, not simply where the unit looks most symmetrical.
The setup should allow you to use the panel comfortably from approximately 6 to 18 inches away. A larger distance increases the area reached by the light but reduces irradiance. Use the model-specific irradiance information and dosing guidance in the manual rather than assuming that closer or longer is always better.
Route power safely
Keep the cable away from the heating element, sharp edges, and walking paths. Use a properly rated outlet outside the sauna or a sauna-rated electrical run installed in accordance with local electrical requirements.
Do not improvise permanent wiring. If the installation requires a new receptacle, hardwired connection, or penetration through the sauna wall, use a qualified electrician familiar with the sauna manufacturer’s requirements.
Choose a secure mounting method
Both Sauna Series panels include hardware for hanging or fixed mounting. Hooga also offers a rolling Sauna Series Floor Stand, sold separately, for installations where drilling is undesirable or the panel needs to remain movable.
Whichever method you choose, confirm that the support structure and hardware can safely hold the panel’s weight under sauna conditions.
Ember vs. Blaze: which sauna panel should you choose?
The choice is primarily about physical fit and coverage, not about one model producing dramatically stronger light.
| Feature | Ember | Blaze |
|---|---|---|
| Best fit | Compact saunas, limited wall height, targeted coverage | Standard-size and larger saunas, broader vertical coverage |
| Dimensions | 20.1 × 12 × 2.2 in. | 36.6 × 12 × 2.2 in. |
| Weight | 15.4 lb. | 22 lb. |
| LEDs | 384 | 768 |
| Power consumption | 180W | 340W |
| Wavelengths | 630, 660, 810, and 850 nm | 630, 660, 810, and 850 nm |
| Irradiance at 6 inches | 111 mW/cm² | 109 mW/cm² |
| Maximum operating temperature | 194°F / 90°C | 194°F / 90°C |
| Ingress protection | IP65 | IP65 |
Choose Ember when:
- Your sauna has limited open wall height.
- You want localized or upper-body coverage.
- You are adding a second panel to an existing setup.
- A 20.1-inch-tall panel fits the room more naturally.
Choose Blaze when:
- Your sauna can accommodate a 36.6-inch-tall panel.
- You want a larger illuminated area and more vertical coverage.
- You want a single panel to reach more of the body in one position.
- You are equipping a standard-size or larger personal sauna.
Blaze has twice the LED count and a larger treatment surface, but measured irradiance at six inches is similar between the two models. Its practical advantage is coverage, not a claim that it delivers twice the intensity.

Three ways to install a sauna red light panel
Wall mounting
A fixed wall installation keeps the floor clear and makes treatment positioning repeatable. Locate a wall stud or use anchors rated for the panel’s weight and the wall construction. Attach the panel using the specified hardware and confirm that it sits securely before connecting power.
The Sauna Series manual lists pilot-hole spacing and model-specific mounting instructions. Follow the manual rather than estimating measurements from the outside of the enclosure.
Suspended mounting
The included hanging hardware can suspend Ember or Blaze from solid ceiling joists. Adjustable cables allow the panel to be leveled and positioned at the intended height. Confirm that every connection is locked and load-bearing before use.
Floor stand
The rolling Sauna Series Floor Stand supports either Ember or Blaze and uses locking casters to hold the panel in position. It can be a good option when wall or ceiling mounting is impractical, when the sauna is rented, or when the panel needs to be repositioned.
Lock the casters before every session. Keep the stand on a stable, level surface with the panel clear of the heater and walking path.
How to use red light therapy in a sauna
- Inspect the installation. Make sure the panel is secure, the vents are unobstructed, and the power cable is clear of heat sources and sharp edges.
- Hydrate before the session. Sauna heat can increase fluid loss even when the light portion of the routine feels comfortable.
- Turn on the panel. Ember and Blaze allow independent control of red and near-infrared channels.
- Select the wavelengths. Use red light, near-infrared light, or all four wavelengths together according to your routine and the product instructions.
- Set brightness and time. Both panels provide adjustable brightness and a timer from one to 20 minutes.
- Choose continuous or pulsed near-infrared light. The near-infrared channel supports continuous output plus 10 Hz and 40 Hz pulse settings.
- Use a practical distance. Position yourself approximately 6 to 18 inches from the panel and refer to the manual’s model-specific irradiance information.
- Pay attention to comfort. Heat exposure and light exposure are separate inputs. End the session if you feel dizzy, overheated, uncomfortable, or otherwise unwell.
- Let the equipment cool. Follow the shutdown and cooling instructions before handling, cleaning, or moving the panel.
More exposure is not automatically better. Start conservatively, follow the manual, and keep the overall heat load of the sauna session in mind.
Should you use red light before, during, or after a sauna?
There is no universal sequence that is right for every person. The practical choice depends on your equipment, heat tolerance, schedule, and reason for using each modality.
During the sauna
Using a sauna-rated panel inside the cabin is the most space-efficient approach and allows heat and light exposure to happen at the same time. It also produces the greatest combined environmental load, so session length and personal comfort matter.
Before the sauna
Using the panel before heating the sauna separates light exposure from the hottest part of the routine. This may be preferable for someone who wants a deliberate light session without extending time in the heat.
After the sauna
A post-sauna light session outside the cabin also separates the modalities. Allow your body to cool and rehydrate rather than immediately adding more time to an already demanding heat session.
The most important point is not the order. It is using each device according to its instructions and avoiding a combined session that exceeds your heat tolerance.
Sauna red light therapy safety checklist
- Use only a panel that the manufacturer specifically rates for sauna operation.
- Confirm that the sauna’s normal temperature stays within the panel’s operating limit.
- Keep the panel away from the heater and concentrated hot spots.
- Maintain the required open space around the enclosure and vents.
- Disconnect power before installing, repositioning, cleaning, or removing the panel.
- Do not touch the metal housing during a hot session.
- Let the panel cool completely before moving it.
- Do not use a damaged panel, plug, or power cord.
- Do not submerge the panel or clean it with high-pressure water.
- Do not use a steam room unless the manufacturer explicitly approves that environment.
- Keep power connections and cable routing compliant with local electrical requirements.
- Keep flammable products and vapors away from the panel and heater.
- Supervise children around the equipment.
- Speak with a healthcare professional before use if you are pregnant, light-sensitive, taking photosensitizing medication, managing a heart condition, or uncertain whether combined heat and light exposure is appropriate for you.
Cleaning and maintenance
Disconnect the panel and allow it to cool completely. Wipe the enclosure and lens surface with a damp soft cloth or paper towel. Avoid bleach, abrasive products, harsh cleaning chemicals, and high-pressure water.
Make sure the panel and surrounding connections are dry before restoring power. Periodically inspect the mounting hardware, cable, plug, vents, and enclosure for damage or loosening.
Frequently asked questions
Can any red light therapy panel go inside a sauna?
No. Use a panel inside a sauna only when the manufacturer explicitly rates it for that environment. Hooga HG, PRO, and ULTRA panels are designed for normal indoor use and should not be substituted for Ember or Blaze inside a heated sauna.
Can Ember and Blaze be used in both traditional and infrared saunas?
Both models are rated to operate at temperatures up to 194°F / 90°C, covering the normal operating range of many traditional and infrared saunas. The specific sauna installation must still satisfy the panel’s clearance, mounting, humidity, and electrical requirements.
Is near-infrared light the same as an infrared sauna?
No. Near-infrared light is a wavelength range used by the Sauna Series panels. An infrared sauna is a heat-producing system. The technologies overlap in name but differ in wavelength mix, output, measurement, and primary purpose.
Does IP65 mean the panel is waterproof?
IP65 means the enclosure is dust-tight and protected against water jets. It does not mean the device can be submerged or used in every wet environment.
Can a sauna panel be used in a steam room?
Do not assume sauna compatibility includes steam-room compatibility. Steam rooms involve very high humidity and direct condensation. Only use electrical equipment in a steam room when the manufacturer expressly approves that installation.
How far should the panel be from your body?
Plan the setup so you can sit or stand approximately 6 to 18 inches from the LEDs. Use the irradiance and dosing information in the Sauna Series manual to choose the distance and session length that match your routine.
Is Blaze stronger than Ember?
Blaze has twice the LED count and covers a larger area, but the two panels have similar irradiance at the same measured distance. Choose Blaze for broader vertical coverage and Ember for a more compact installation.
Do Ember and Blaze include mounting hardware?
Both models include hardware for hanging or fixed installation. The rolling Sauna Series Floor Stand is sold separately and fits either model.
Can you use Ember or Blaze outside the sauna?
Yes. Both panels can also operate in a normal indoor wellness or recovery space. Disconnect the panel, allow it to cool, and move it safely before changing locations.
Build the setup around your sauna
The best sauna red light therapy panel is not automatically the largest one. It is the model that fits the available installation area, reaches the body regions you want to expose, maintains the required clearance, and can be powered and mounted safely.
Ember provides sauna-ready construction and four wavelengths in a compact 20.1-inch-tall format. Blaze expands the treatment area to 36.6 inches of vertical coverage while retaining the same width, heat rating, wavelength mix, and control system.
