Welcome to Your Luminar Sauna

Congratulations! You are now the owner of a Sun Home Luminar Outdoor infrared sauna. This manual will help you get started, stay safe, and enjoy every session to the fullest.

Your Luminar sauna uses infrared light and heat together to deliver two powerful benefits at once:

• Far infrared heat penetrates deep into your muscles and tissues, boosting circulation and helping your body repair and recover.
• Heat creates a detoxifying sweat, activates heat shock proteins, and gives your body the positive stress it needs to get stronger.
• Full-spectrum heaters on the glass wall add near and mid infrared wavelengths, giving you a broader range of wellness benefits.

Science shows that regular infrared sauna use can help improve circulation, ease pain, support detox, reduce stress, speed up muscle recovery, improve sleep, and boost energy. Your experience is unique. Listen to your body and enjoy the journey.

Safety Warnings

Electrical Safety

• Ensure the sauna is correctly assembled before use according to the Sun Home Luminar Assembly Guide instructions and electrical specifications. Improper assembly may cause malfunction or injury.
• Plug the sauna into a properly grounded AC outlet on a GFCI protected circuit.

Outdoor Sauna Use Protocol

The Luminar is a full-spectrum infrared sauna rated for outdoor use.

The sauna must be installed on a flat, level surface with drainage. The sauna should not be installed in an area where water may accumulate or puddle.

The concrete pad or other surface should extend at least 6 inches beyond the sauna on all sides.

In environments with high winds, Sun Home offers a free Roof Security Cable kit to anchor your sauna. Please contact us at info@sunhomesaunas.com to request this.

Use of the waterproof canvas cover is optional, but consistent use will preserve the exterior of the sauna and support heat retention in cold weather.

Do not allow snow or precipitation to accumulate on the roof or around the base of the sauna.

Review the warranty for details on coverage regarding pests and weather-related damage.

How to Use Your Sauna

The Luminar is an outdoor full-spectrum infrared sauna which may require a longer warm-up time than indoor models depending on the ambient air temperature. No pre-heating is required before entry. You may begin your session as soon as the sauna is turned on, though optimal temperature is typically reached after 30–45 minutes.

Before Your First Session

• Drink 8–16 oz of water before getting in.
• Remove jewelry. Avoid putting lotions or oils on your skin before a session.
• Bring a towel and prepare to sweat!
• Wear minimal, loose clothing or wrap yourself in a towel.
• Always check with your doctor first if you have any health conditions.

Starting the Luminar Sauna

1. Make sure the sauna is plugged into the dedicated GFCI outlet. Press the GFCI RESET button to confirm power is live.
2. To activate the ambient lighting during your first session, point the remote at the ceiling and press the “On” button.
3. Press the Power button on the control panel to turn the system on. The button backlight will turn red and the current temperature will display on screen.
4. Press the Heating button (the flame/heat icon) to activate the infrared heaters. A red border around the button indicates heating is ON; green means OFF.
5. Press Mode until the Temp indicator light is on. Use the up/down arrows to set your desired temperature. Recommended: 120–160°F (49–71°C). Range: 90–170°F.
6. Press Mode until the Time indicator light is on. Use the up/down arrows to set your session time. Range: 5–60 minutes.

Allow 30–45 minutes for the sauna to warm up (longer in cold weather). You may enter at any time during warm-up.

The default setting is 151°F (66°C) and 60 minutes. On first use, verify each heater is warming up after a few minutes.

During Your Session

• If you’re new to infrared saunas, low and slow is best. Beginners: start at 115–120°F for 10–15 minutes. You may slowly increase time and temperature with each session if desired.
• Sip water if you feel thirsty. Stay hydrated throughout the session.
• Exit immediately if you feel dizzy, lightheaded, or unwell.
• Keep sessions to 45 minutes maximum. Typical sessions are 20–45 minutes.
• Do not bring phones, tablets, or other electronics inside. Battery heat is a fire risk.
• Do not use while under the influence of alcohol or medications that affect your response to heat.
• After 2 hours of continuous use, shut the sauna down for at least one hour.
• Do not place objects on or around the full-spectrum heaters. They are extremely hot and will cause burns.

After Your Session

• Turn off the heaters, then press the Power button to shut down the sauna.
• Leave the door open so the inside can air out and dry.
• Unplug the sauna when not in use.
• Wipe down the bench and inside walls with a dry or lightly damp cloth.
• Let your body cool down slowly.
• Drink water or an electrolyte drink to rehydrate.

Bluetooth Music

• Enable Bluetooth on your phone and scan for the device SAUNA BT.
• Connect to SAUNA BT and stream music through the sauna’s built-in speakers.

Note: Volume must be adjusted from your phone; the LED panel has no volume control.

Heat-Up Times & Ambient Temperature

The Luminar is designed for outdoor use, so heat-up time may vary depending on ambient conditions. In cold or windy weather, allow additional time to reach your desired temperature. To ensure maximum heat retention, keep the protective cover on throughout the heat-up process.

Factors That Affect Heat-Up Time

• Outdoor ambient temperature: below 40°F adds 20–30+ minutes.
• Wind: strong winds draw heat from the sauna exterior. Sheltered placement helps.
• Protective cover: keeping it on during warm-up traps heat and reduces time significantly.
• Surface type: concrete or basement floors are cooler and slow heat-up. Tile or insulated flooring is better.
• Snow and ice: must be cleared from roof and base. Accumulated snow will significantly impact performance.
• Door closed during warm-up: always keep the door closed until your target temperature is reached.

Chromotherapy & Ambient Lights

Your Luminar sauna includes built-in color LED lighting, called chromotherapy. You can use it during any session to enhance your experience. There are nine color modes, each linked to different wellness benefits.

How to Use Chromotherapy

The chromotherapy panel is a square glass panel installed in the ceiling and features the Sun Home logo. The Luminar 2 has one chromotherapy panel, and the Luminar 5 has two.

To activate chromotherapy, first power the sauna on and press the Bright Lightbulb button (12) to toggle chromotherapy on. The button turns red when ON, green when OFF.

The display will show LX when in color selection mode. Press the button to cycle through modes L1–L9.

Long press the Bright Lightbulb button (12) to adjust brightness (B1–B8) while in any color mode.

The chromotherapy feature is not currently integrated with the Sun Home App. Only the sauna control panel can be used to control the square chromotherapy panel in the ceiling.

Color Mode Guide

These associations are based on traditional chromotherapy principles for general wellness reference. Results vary by individual.

Ambient LED Lights

Your Luminar includes ambient LED light strips on the backrests and under the seats. This is not the same as the chromotherapy light.

How to Use Ambient LED Lights

These can be controlled using the white remote control with the color wheel. To activate these lights, point the remote control towards the ceiling and press power on. You can rotate the color wheel to choose your preferred ambient light color.

Red Light Therapy

Optional Red Light Therapy Accessory

Red Light Therapy is an optional added accessory for the Luminar. If you purchased the Red Light Therapy Panel, it attaches to the glass door using the included bolts, and connects to power through the sauna using the spring wire cord and plug.

Red light therapy uses red and near-infrared light to support a variety of conditions. It can help regenerate cells, restore cell function, and increase blood flow, which can help relieve pain and heal. Red light therapy can also help with muscle and joint pain and stiffness, and can relax muscles.

Using the Red Light Panel

• Controls for the red light panel are located on the side of the panel.
• To turn on the red light, select NIR / near infrared light (1), RED / visible red light (2), or both.
• Set the desired session time using the DOWN/UP buttons (3, 4).
• Indicator light (5) will glow red when the RED light is on, and indicator light (6) will glow green when the NIR light is on.
• Recommended: 20 minutes, 3 times per week, at 6–24 inches distance.

Safety When Using Red Light with Sauna Heaters

Do not look directly into the red light panel. Prolonged direct staring may cause eye strain or retinal stress over time. Protective goggles are optional — you may instead look away or close your eyes. Carefully read the warnings below regarding goggle use.

• Always sit down and position yourself away from the full-spectrum heaters before putting on protective goggles.
• Do not move or reposition while wearing goggles. If you need to move, remove the goggles first and confirm the location of all heating elements before proceeding.
• Keep a safe distance from all heaters at all times. Contact with any heater surface can cause severe burns.
• Red light therapy panels are not FDA-approved to diagnose, treat, or cure medical conditions. For general wellness use only.
• Do not use over open wounds or active infections.
• Do not use red light therapy if you have been diagnosed with melanoma or any form of skin cancer, or if you are undergoing cancer treatment. Consult your physician or oncologist before use if you have a history of skin cancer, are sensitive to light, or are taking photosensitizing medications. This device is not intended to diagnose, treat, cure, or prevent any disease or medical condition.
• Consult your physician before use if you have photosensitivity disorders, pacemakers, metal implants, heart disease, epilepsy, or are pregnant.
• Ensure the sauna is correctly installed and grounded to prevent electrical hazards.
• Regularly inspect the panels for damage, especially to electrical components. Discontinue use immediately if repairs are needed.
• Do not alter the equipment, as this could void warranties and create safety risks.

Care & Maintenance

As an outdoor sauna, the Luminar requires regular maintenance to protect the wood, electrical components, and your warranty.

After Each Use

• Dry off the backrests, bench, and floor with a towel or lightly damp cloth.
• Leave the door slightly open so the inside can air out and dry completely.
• Unplug the sauna.

Weekly

• Clean inside surfaces with a cloth slightly dampened with warm water. For best results, use the Sun Home Cleaning Kit available on our website.
• For perspiration stains, use a small amount of soap or detergent in warm water with a soft-bristled scrub brush.
• Do not use chemical cleaners, bleach, or abrasive pads. These can damage the wood and void your warranty.
• Check the power cord connections. Make sure the cord is not pinched, bent, or under a rug.
• Check the ventilation grill for dust and clear it if needed.
• Inspect benches and backrests for any loose screws or hardware.

Every Month

• Inspect all visible cable connections at the back of the sauna and red light panels.
• Inspect the control panel for any signs of wear.
• Inspect benches and backrests for any loose screws or hardware.
• Test all heaters, lights, and speakers for proper functioning.
• If the sauna is in a humid environment, check the wood panels for any signs of moisture damage or warping.
• If in use, verify the Roof Security Cables are properly secured.
• Check all visible cable connections inside the roof panel. Inspect for any signs of moisture ingress.
• Sanding: perspiration may darken the wood over time. Light sanding with fine-grit sandpaper removes staining. A sanding block works best.
• Inspect the door hinge and soft-close mechanism for proper operation.
• Before periods of non-use, unplug the sauna from the outlet.

Snow & Weather

• Remove snow from the roof, base, and surrounding area before each use in winter.
• The sauna is not designed to withstand more than 1 foot of snow on the roof; as soon as possible, clear all snow from the roof and base during snowstorms.
• Do not use the sauna during lightning or electrical storms.
• Keep plants, grass, soil, and debris away from the base at all times.

Frequently Asked Questions

Do I need to pre-heat before getting in?

No. You can enter the sauna as soon as it turns on. However, the optimal temperature range of 100–129°F is typically reached after 30–45 minutes. Beginners are encouraged to start sessions at lower temperatures during the warm-up phase.

Why does my sauna take longer to heat in cold weather?

The Luminar is an outdoor sauna and ambient temperature directly affects heat-up time. Below 40°F, allow at least 60 minutes. Keep the protective cover on during heat-up to trap heat, and ensure the door is closed. Clear all snow from the roof and base before use.

Why do the heaters turn off during my session?

This is normal and by design. The heaters cycle off automatically once the sauna reaches your set temperature to maintain it efficiently and protect heater lifespan. Do not manually keep the heaters on. Set your temperature and leave the controls alone.

What electrical outlet does the Luminar require?

The Luminar runs on 240V and requires a dedicated GFCI-protected circuit installed by a licensed electrician. The 2-person model requires a 20A circuit (NEMA L6-20). The 5-person model requires a 30A circuit (NEMA L6-30). Never use a standard 120V household outlet.

Do I need to use the protective cover?

No, but it does protect the exterior of the sauna and will support heat retention during colder seasons.

What happens if snow accumulates on the roof?

Remove snow from the roof, base, and surrounding area before each use. Your sauna is not designed to withstand more than one foot of snow. Failing to clear snow may void your warranty and damage the unit.

Can I use Bluetooth and USB audio?

Yes. Press the Bluetooth button to enable Bluetooth and pair your phone to BT-sauna. Volume is adjustable on the control panel (press Mode until Vol lights up, then use the up/down arrows, range 0–30). For USB, press the USB button and plug in a flash drive with MP3 files.

Does the Luminar have chromotherapy?

Yes. There is a square chromotherapy light in the ceiling. Press the color light button to cycle through modes L1–L9. When the light button backlight is red, lighting is ON; green means OFF. Long-press the color button to adjust brightness (B1–B8) while in a color mode.

Is the Red Light Therapy panel included?

Red Light Therapy is an optional add-on, not included standard. If you purchased the add-on, it attaches to the glass door with the included bolts. Controls are on the side of the panel. Recommended use is 20 minutes, 3 times a week, at 6–24 inches distance.

What Wi-Fi does the app require?

The Sun Home Saunas app requires a 2.4 GHz Wi-Fi network. 5 GHz networks are not currently supported. Note that the Luminar uses a different pairing method than other Sun Home products. See the App Connection section.

Is it normal to sweat a lot?

Yes! We recommend drinking water with electrolytes before, during, and after your session.

Optimal Wood Care

Sun Home Saunas uses the highest quality wood. Minor dents, scratches, and scuffing are normal and do not affect the sauna’s integrity or operation.

Variations in the color or grain, and irregularities such as fine cracks, are not considered defects. During normal operation, wood may crack due to climate changes, which will not affect structural integrity.

Prior to shipping, all wood material is inspected for consistency, color, and quality. Slight blemishes, scratches, or scuffs can happen in transit. Exterior blemishes can be concealed by using a small amount of furniture polish, oil, or other furniture treatment. Interior blemishes, scratches, or scuffs can be either left alone or sanded. Avoid treatments with benzene or high alcohol concentration.
