Sunlighten VS Clearlight Saunas

Can’t make up your mind on Clearlight infrared sauna VS Sunlighten? So, maybe you've read online reviews about sauna. Also, you may have joined a sauna detox group that promotes a specific brand. Or, you've had a talk with a representative from either company to make the best decision.

When you contact a sauna company, each company will tell you that their sauna is the best. I mean, who would badmouth their own company?

Here’s the three main differences to consider:

  1. Heating Technology
  2. Heater Effectiveness and Placement
  3. Warranty & Company Longevity 

 The #1 difference between our saunas is the heating technology. Most people notice when using Clearlight Saunas vs Sunlighten Saunas a huge difference in how quick they start sweating, the amount of sweat, greater core temperature increase, and how good they feel after using the sauna. 

Note: Sunlighten claims that their heaters are the only ones that have clinical data proving their saunas create a core temperature increase. If you read this study and compare it to our video and report from Arcadia Cancer clinic, you will find ours is much more credible. There is nothing clinical or 3rd party about their study. It’s done in an old factory in China with their old generation saunas and heaters from 2001. 

Our True Wave™ carbon/ceramic far infrared heaters are designed specifically to warm the body and stimulate the lymphatic system, cardiovascular system, immune system and parasympathetic nervous system. See a video of this effect at Arcadia Cancer clinic where our saunas are used exclusively HERE. This effect provides the environment for the body to heal naturally.

Clearlight Infrared™ Full Spectrum (Sanctuary)

There is confusion about what full spectrum is and how to deliver it in an infrared sauna for HEAT THERAPY.

The infrared spectrum is comprised of near, mid and far infrared. This is how we describe a full spectrum infrared sauna.  

While the majority of the benefits you receive in your Clearlight Jacuzzi® sauna comes from the far infrared band, there are added benefits and enhancements by adding in all three wavelengths.

From our research, we discovered that the best way to deliver whole body infrared heat therapy is with full spectrum halogens that peak in Near Infrared. This provides a higher intensity of directed heat and also allows the cabin to warm up faster. Most people notice they sweat more and have the option for greater heart rate increases with higher air temperatures.  

Sunlighten Full Spectrum (mPulse)

The Sunlighten mPulse sauna is made with a combination of sprayed carbon on a thin plastic film for far infrared wavelengths and wires running through the the film to create the higher mid-infrared temperatures and to warm the carbon. They also use non-heating Near Infrared LED’s that sit behind bamboo covers along with the other infrared emitters. All of these components are then turned on and off based on whichever button you press on the control panel that claims specific benefits i.e. cardiovascular.  

There are several problems with this that we find are hazardous and also nullify the claimed benefits.

  1. It creates a HIGH EMF/ELF environment. We have tested the Electric Fields in the mPulse saunas to be upwards of 20 times above the threshold of concern according to the world health organization. Their LOW EMF/ELF claim applies to their Signature saunas only. See below for more details.
  1. The bamboo coverings distort the wavelengths, nullifying the effects of the NIR wavelengths and reducing the effects of the Near and Far infrared. While we recognize the benefits of Non-heating Near Infrared delivered in Specific wavelengths from LED’s, we also understand that direct exposure to the skin from the emitter is essential and required. You can see our LED Light Therapy option HERE. This attaches to the door so the front of the body can have direct exposure to the emitters. This therapy is called Photobiomodulation (intracellular stimulation by light), not Whole Body Infrared Heat Therapy.
  1. Though Sunlighten had a patent on what they call a 3-in-1 sauna, it is not something we would ever consider and is not effective. The idea that a specific wavelength and benefit sauna can be owned or used for profit comes from the Pharmaceutical industry where the owners of this company used to do their business. Pressing a button that says cardiovascular or weight loss does not improve your ability to receive those benefits. All it does is turn the components on or off by increasing and decreasing the wattage. 

Our philosophy is that you cannot own a wavelength or benefit, and that you should receive all the benefits from all wavelengths throughout your entire session. 

With that said, it takes about 15 minutes for OUR heaters to reach peak output. 

We recommend using your Clearlight Infrared Sauna as follows: Turn your sauna on with the thermostat at its highest setting. Warm your sauna up for 15 minutes. After 15 minutes or so, get in your sauna and set the duration of your session (20-45 minutes is recommended). By the end of your sauna session, the internal temperature will be between 115° - 125°F. Remember, it is not the air temperature that is doing the healing; it's the combination carbon and ceramic heaters emitting the infrared that is absorbed by your body. This will raise your core body temperature causing you to sweat. And sweat you will--so please remember to rehydrate and get plenty of electrolytes!


We pioneered LOW EMF in 2007 when Sunlighten was still saying 30 times above the threshold of concern was safe. You can go to Sunlighten's website and see that the 3rd party verification for the low EMF only applies to their Signature Saunas, not their mPulse saunas. 

ALL of our saunas are LOW EMF. 

If you test our saunas, there will be ZERO EMF reading where you are sitting with virtually no exposure to EMF's in all the measurable fields. The W.H.O. recommends below 3.5 mG and 1,000 mV. We guarantee our saunas to read below the threshold of concern. You can test the A/C magnetic and Electric fields with a reliable meter.  

We are also the only company to cancel ELF (electric fields) 3-5 times below the threshold of concern. We have measured Sunlighten to be 20x above the threshold of concern. You can learn see our EMF/ELF page HERE. You can also learn more about EMF/ELF from Lloyd at if you would like to go into further detail.


Heater Placement 

All Clearlight Infrared™ saunas are built with a full 360-degree coverage of our True Wave Heaters on your body with no cold spots in the sauna. Built 24” from the bench on the back and side walls, under the bench, next to your calves, in the floor, and on the front panels, we concentrate the infrared energy on your body so there is no wasted energy.

Sunlighten’s saunas all have cold spots and do not provide full body infrared therapy with heaters placed far behind the bench and missing heaters on the front. This is in part why most users reflect to us that it takes a long time to warm up, they don’t sweat much, and experience cold spots in the sauna. On their signature saunas, you also see heaters being built above the head, which is wasted infrared energy. Anything above the shoulder cannot be absorbed, so it makes no sense to build it that way. 

Warranty and Company Longevity

 Our Warranty and service record is more exceptional in comparison to Sunlighten based on our company setup and track records if you consider public reviews, the Better Business Bureau, and the quality of parts we use to provide our lifetime warranty. 

Sunlighten’s Warranty only covers the sauna and parts for 7 years. This means that if any part becomes defect after 7 years, you will have to pay for replacements or buy a new sauna.

Benefits of Using Clearlight Sauna

  • Relieve muscle and joint pain with the heat penetrating the deep tissues
  • Better sleeping patterns as serotonin (relaxing hormone) levels increase
  • Cleanses your skin, leaving you fresh and glowing
  • Body detoxification, getting rid of built-up toxins in your system via sweat
  • Boosts your immune system by increasing the body temperature of your core. The temperature increase gimmicks the body to a short-term state of fever. As a result, it triggers the natural immune response of your body
  • Manages your blood pressure and improves your cardiovascular system
  • It relieves your stress thanks to the sauna's ability to reduce stress hormones. In turn, it stimulates the parasympathetic nervous system giving the rest you need


Stay away from excessive alcohol consumption. It may cause dehydration, arrhythmia, and unexpected death. Spend less time in the sauna, about 20 minutes. If you are using the sauna for a fast time, spend about 10 minutes until you get used to it.

Irrespective of your sauna choice, you'll lose body fluids through sweat. Drink two-four glasses of water after a sauna session. Children above six years can use the sauna but under supervision. They should spend 10 minutes or less each.
