Sunlighten and Clearlight® Saunas are currently the two most prestigious brands in the infrared sauna space. Both companies offer:

  • full range of premium-quality infrared saunas.
  • full-spectrum saunas for maximal health benefits and heating - although these have subtle differences. 
  • excellent service and warranty, but only one company is the best in this domain
  • add-ons - but the add-ons of one of these companies are superior.

For that reason, I decided to create the best infrared sauna comparison between Clearlight Saunas Vs Sunlighten Saunas.

Step by step, you’ll learn why Clearlight® Saunas are the best overall option for most people. 

So whether it’s the infrared sauna heaters, warranty, or add-ons, Clearlight® Saunas offers the highest-quality saunas on the market currently.

Before we dive in, we want to be honest that we’re part of the Clearlight Saunas team for non-US regions. We nevertheless aim to be as transparent and objective as possible in my analysis of these different saunas. Based on these facts and analysis, we believe Clearlight is the superior sauna.

Let’s find out why that is the case:

Fact Overview: Two Examples

In this section, I’ll give you two examples of two similar models offered by Clearlight and Sunlighten.

First, I’ll start with a 2-person far infrared sauna model. That comparison uses the Clearlight® Premier 2-Person Far Infrared Sauna and the Signature II far infrared from Sunlighten.

Product Comparison - Sunlighten vs Clearlight

Features Sunlighten Signature II Clearlight® Premier Far Infrared Sauna
Size 197 x 129 x 116 cm 193 x 127 X 112 cm
Heaters SoloCarbon® Ceramic Heaters emitting 1,650W at 230V True Wave™ carbon emitting 1,750W at 230V
Heater Placement Targets the entire body, including the head Focus on the body and extremities only
Light Emitted High-quality far infrared High-quality far infrared
Wood Type Basswood or eucalyptus Western red cedarwood
Potential Addons Vibrational resonance therapy Salt therapy, vibrational resonance therapy, red light therapy tower

Note that the Signature II’s heater placement towards the head is not necessarily advantageous. The human head is the weakest link in your sauna sessions and limits how long you can spend time inside an (infrared) sauna and sweat. 

Next up, I’ll consider a 4-person full-spectrum sauna. That comparison uses the  Clearlight® Sanctuary Yoga 4 Person Full Spectrum Sauna and the Sunlighten mPulse Discover.

Sunlighten mPulse Discover vs Clearlight® Sanctuary Yoga

Features Sunlighten mPulse Discover Clearlight® Sanctuary Yoga Full Spectrum Sauna
Size 199 x 179 x 179 cm 193 x 196 x 153 cm
Heaters SoloCarbon® NIR, MIR, and FIR emitting 4,200W at 230V True Wave™ carbon & ceramic and two 2 x 500W Full Spectrum Heaters emitting 3,360W at 230V
Heater Placement Target entire body including the head. No 360° coverage of body and extremities Focus on body and extremities only - covering them 360°
Light Emitted Good far and middle infrared coverage but only a tiny part of near-infrared Covers entire near, middle, and far infrared spectrum
Wood Type Eucalyptus, basswood, or eucalyptus/cedar combination Western red cedar
Addons Vibrational resonance therapy Salt therapy, Vibrational resonance therapy, Red light therapy tower

So, while the Clearlight® Sanctuary 4-person Full Spectrum Sauna seems to have lower power output, there are no panels aimed at the head once again.

Sunlighten Sauna Products

Sunlighten specialises in infrared saunas in the same way Clearlight® Saunas does. Sunlighten doesn’t offer many products unrelated to infrared saunas, except for one infrared spot-treatment device called the “lumiNIR”.

Products are sold to residential and commercial clients and have been in business for over 20 years. Today, Sunlighten has offices on four different continents. Sunlighten has a large online following, with many influencers promoting their products in the natural health and wellness space.

Sunlighten has four product ranges: the premium mPulse, the Amplify series, the Signature far infrared series, and a portable infrared sauna called the Solo System. All these saunas are indoor saunas, not for outdoor use. Only the mPulse and Amplify series use full-spectrum heating technology. 

The stated goal of these sauna series is different:

  1. The mPulse series is aimed at maximum overall health improvement and luxury
  2. The Amplify series is affordable yet offers maximum heating - which can be helpful to athletes
  3. The Signature series is the basic far infrared offering
  4. The portable Solo System is affordable and transportable

Different types of timber are available for Sunlighten’s infrared saunas. These are basswood, eucalyptus, and cedar for the UK. The cedarwood can only be used inside the mPulse sauna. During this process, Sunlighten focuses heavily on sustainably sourcing their timber. Some of their timber is FSC-certified.

All infrared saunas also come with BlueTooth and audio connectivity. The same is true for an ergonomic backrest. Add-ons are also available, such as vibrational resonance therapy, which Sunlighten call “acoustic resonance therapy”. 

Compared to many other competitors in the UK infrared sauna space, Sunlighten offers a premium product. Sunlighten Saunas aim is not to compete with the market's budget or mid-tier infrared sauna offers.
