Far Infrared & Full Spectrum Sauna Heaters:
Low EMF / Low ELF Sauna Technology

As a leader and innovator in the infrared sauna industry for over 20 years, Clearlight has been manufacturing infrared saunas that are both luxurious and effective. While the cabins are exceptional quality, the therapeutic benefits of infrared heat are the main focus.

Over the last eight years, there has been a big debate as to whether carbon heaters or ceramic heaters are “better”. Carbon heaters produce high quality, long wave infrared heat, but the problem is they do not produce a lot of infrared heat. Ceramic heaters are powerful and emit a lot of infrared heat, but the wavelength tends to be shorter, thus less therapeutic.

The Clearlight R&D department has ended that debate by introducing the ONLY combination Carbon/Ceramic far infrared heater. Clearlight True Wave™ Far Infrared Heaters combine Carbon and Ceramic to produce healing infrared heat that is unmatched. The heaters are comprised of micro-thin carbon fibers (1/1000th the thickness of a human hair) combined with our patented micro fine ceramic compound for higher infrared output (emissivity). Heaters are manufactured in factory. This is a special process with carbon/ceramic layers alternated with layers of a woven substrate which combine under high heat and pressure to make one heater at a time.

This innovative process produces a heater with tremendous output and high thermal emissivity. The heater is then tested under power for several hours and measured for the electrical draw, surface temperature, and emf output in twelve locations.

The carbon within the heater allows the heater to produce long wave far infrared heat. This long wave infrared heat penetrates deeper into your body and the infrared heat is more readily absorbed. The ceramic in our heaters gives the heaters a very high infrared output when compared to traditional carbon heaters so the heat focuses directly on the body. All Clearlight Sauna® models utilize True Wave™ Far Infrared Heaters.

Clearlight has also developed the first and only virtually no-EMF combination carbon/ceramic heaters. This patent pending process allows us to cancel out virtually all of the EMF (electromagnetic fields).

Using a laboratory grade EMF meter and measuring directly on top of the True Wave heaters, the heater has an average EMF output of about 2.5 milligauss (mg). Compare that to over 100mg for most competitors carbon based heaters. In addition, when tested, there is virtually no EMF.

WHY TRUE WAVE™ FAR INFRARED HEATERS ARE BETTER FOR YOU?

The larger size of True Wave™ Far Infrared heaters mean more surface area, resulting in lower surface temperature. The result of this low temperature is that heaters produce more FAR or LONG wave infrared heat which is more therapeutic for your body. This means better performance within the optimal wavelength range of 6 to 12 microns with a large portion of wavelengths at 9.4 microns. The human body absorbs more infrared at 9.4 microns.

With the high far infrared output (emissivity), you not only get the highest quality infrared heat, but you get a lot of it, and right where you want it – your body core. Heaters are positioned so that they surround the body, concentrating the heat on your body core.

The key to infrared therapy is heating your body directly so you want heat on the front of your body and on the back of your body. Every Clearlight Sauna® model has heaters on the front wall, back wall, side walls, underneath the bench, next to your calves and in the floor. Surround Yourself In Wellness™ with Clearlight infrared saunas.

Jacuzzi® Saunas Core Body Temperature and Heart Rate Study

All Clearlight Infrared Sauna® models have been shown to raise core body temperature. The data above from the Arcadia Cancer Clinic in Germany shows an average of a 3% core body temperature increase in a 40 minute Clearlight Infrared Sauna session.

All Clearlight Infrared Sauna® models have been show to increase your heart rate during a sauna session. The data above from the Arcadia Cancer Clinic in Germany shows an average of a 68% increase in heart rate in a 40 minute Clearlight Infrared Sauna session.

WHAT TO LOOK FOR WHEN CHOOSING A FAR INFRARED HEATER

The following are a few questions to ask when comparing various heaters:

1) What is the surface temperature of the heater?

The is one of the most important questions as it determines the size the of the infrared wavelength and the overall effectiveness of the heater. The two scientific principals that govern infrared emissions are called Planks Law and Weins Law. Both of these scientific laws have an equation with several constants and the only variable is the surface temperature of the heater. They both say that the lower the surface temperature of the heater, the longer the infrared wave will be and the more effective the infrared heat will be for you.

2) Does the sauna have front and back heaters?

One of the keys to sweating and effective detoxification in an infrared sauna is warming your body and raising your core body temperature. You want to find a sauna that heats both the back and front of your body. You cannot effectively detox in an infrared sauna without warming your front core. Many saunas on the market today leave the front heaters out or have very small front heaters for aesthetic reasons. Clearlight True Wave™ heaters are positioned so that they cover your full back area and the front heaters are positioned so that they are aimed at your front core. They do an excellent job of warming your body core and raising your core body temperature.

3) Is the far infrared heat directed where it’s most needed?

The problem with traditional carbon heaters is that, while they produce high quality infrared heat, they don’t produce a lot of it and it is not concentrated on your body. These heaters work well when they are within a few inches of your body as in some of the lay down infrared units, but not when they are in a large sauna cabin. The heaters go all the way up over your head and are really just heating the sauna cabin air. Because infrared heat travels in a straight line, you want to make sure that the heater directs the heat toward your body core, not just into the air around you.

4) Radiant heat vs. reflected heat:

You will see many heaters on the market that are a thin, single rod with a metal reflector behind it. Generally, these heaters produce low quality far infrared heat when compared to a large flat panel far infrared heater. First, a single rod heater must run at a much higher surface temperature than a large flat radiant heater to produce sufficient infrared heat. As mentioned above, the higher the surface temperature the less effective the infrared heat will be.

Clearlight Infrared Heater Comparison Study

GENTLE HEAT THAT PENETRATES DEEP!

Because of the lower surface temperature of True Wave™ Far Infrared Heaters, sitting in your Clearlight sauna is more enjoyable. You’ll find the heat in your Clearlight Sauna® model gentler than most, yet deeper and more penetrating – overall a better sauna experience.

In their book Beyond Antibiotics, Drs. Michael A. Schmidt et al. state the following:
“Saunas are being used by some doctors to stimulate the release of
toxins from the bodies of their patients. They have found that a lower temperature (105-125 F) sauna taken for a longer duration is most beneficial. These low temperatures stimulate a fat sweat, which eliminates toxins stored in fat, as opposed to the high temperature sauna, which encourages a water sweat.”

Our True Wave™heaters reach optimal temperature very quickly so your sauna is ready for you to use in 10 – 15 minutes.

Clearlight SAUNAS USE TUNED FAR INFRARED

The human body sends and receives far infrared waves. The range of far infrared waves generated by the human body is 6 to 20 microns. The optimal micron output range of an infrared heater is between 6 and 12 microns which is very close to the resonant frequency of a water molecule and the optimum infrared absorption rate of the human body. This similarity makes sense since our bodies are almost 70% water. This range, sometimes called the “Vital Rays” appears to have special regenerative effects on the body.

When far infrared waves are applied to water molecules, these molecules begin to vibrate. This vibration reduces the ion bonds and the eventual breakdown of the water molecules causes encapsulated gasses and other toxic materials to be released.
The result of Clearlight True Wave™ patent pending heater designs allows for better performance well within this vital wave range of 6 to 12 microns with a good portion of wavelengths at the frequency at which a water molecule resonates or vibrates. This vibration causes a release of cellular toxins such as mercury, aluminum, cholesterol and toxic gasses such as sulfur and formaldehyde. This optimal micron output also allows for deeper penetration of far infrared heat, which improves pain relief, detoxification, circulation, and increased peripheral blood flow.

CARBON/CERAMIC COMBINATION FAR INFRARED HEATERS COMPARED TO OTHER HEATERS

Don’t be fooled by marketing hype and supposed studies stating only one material is better for producing far infrared heat – know the facts. When evaluating a material for it’s properties to give off far infrared heat, evaluate its “emissivity”. Emissivity is the measure of an object’s ability to emit far infrared energy. Emissivity can have a value from 0 (shiny mirror) to 1.0 (blackbody).

Raytek, one of the leading infrared instrument manufactures has the following emissivity tables on their website. When reading the table, please note the values in 5-14 micron ranges – the “vital” range for healing the human body (the symbol μm stands for “micron”). You will see ceramic has an emissivity of .95 – the closest to a perfect black body at 1.0. That is why the patented ceramic compound that is added to True Wave™ heaters is so important.

Please note the highlighted entry’s in the table:

> Table for Metals (Cermaic vs. Steel and Incoloy Rods)

Most infrared heaters used in competitors’ saunas were designed for industrial use. These infrared heaters are used to cure the paint on cars because it heats the paint from the inside out or as room heaters. Clearlight Infrared True Wave II heaters were designed specifically for use in saunas and they were designed to heat the human body.

Clearlight True Wave™ Full Spectrum Infrared Heaters

All Clearlight Sanctuary Sauna™ models include True Wave™ Full Spectrum infrared heaters. These heaters are high output infrared heaters producing near, mid and far infrared. Every Clearlight Sanctuary Sauna™ model has 1,000 watts of full spectrum infrared. That’s 25 times the power of the closest competitor.

What Is Full Spectrum Infrared?

Near, Mid and Far Infrared

The infrared spectrum is comprised of near, mid and far infrared. While the majority of the benefit you receive in your Clearlight sauna come from the far infrared band, there are added benefits and enhancements by adding in all three wavelengths.

 

Clearlight True Wave™ Full Spectrum heaters emit about 1/3 near infrared, 1/3 mid infrared and 1/3 far infrared. The following are some of the benefits of full spectrum infrared therapy:

  • Near Infrared is the shortest wavelength, and will be absorbed just below the surface of the skin creating a sweat that promotes healing and revitalization.
  • Mid infrared is a longer wavelength that can penetrate deeper into the body’s soft tissue increasing circulation, releasing oxygen to reach injured areas.
  • Far infrared is the longest wavelength which penetrates the fat cells causing vasodilation, where the fat cells vibrate to expel toxins, resulting in the greatest levels of detoxification and stimulate your metabolism to aid in weight-loss.

Patents / Patent Pending

As innovators in the infrared sauna industry, Clearlight founder, Dr. Raleigh Duncan, has patented or has patent pending’s for much of the technology in use. You can see just a few of the Clearlight Sauna® Patents by clicking the titles below:

I’ve had the Clearlight sauna in operation for 2 weeks now and my wife and I are loving it. It has helped her rheumatoid arthritis and osteoarthritis pain immensely – she’s in it every day. The biggest thing I’ve noticed is the improvement in the quality of my sleep. I go to sleep more readily when I retire, sleep sounder, and don’t get up in the night as often as I did pre-sauna. I was out of town this week for 3 nights and really could tell a difference in sleep quality since I did not have it available.

The sauna is up, assembled, plugged in and we started using it over the weekend. We are thrilled with it. I really could not be happier. My doctor had recommended that I try one at a local body care place before we invested in our own. The one they have there is not a Clearlight and it’s fine but the Clearlight Sauna is much nicer. The Clearlight just seems to be higher quality overall. It’s better built and more comfortable as well. I am glad we got the three-person size. When G and I are in there together we have room to spread out a little.

A contractor friend of ours was over to visit and he pointed out details in the woodworking of the cabinet I would not have noticed otherwise. He was very impressed. Thanks!

I’ve owned and used my Clearlight Sauna for about three months now and thought I’d let you know my impressions regarding its effectiveness and value. I absolutely love my sauna! Thank you for selling such a wonderful and effective product! My Clearlight sauna has made a very positive and significant improvement in my overall health and quality of life. I have only one major regret – I wish I had purchased it many years ago, so I could have started reaping the benefits of using it that much sooner. The main benefits I’ve noticed from using the sauna are:
1. Better recovery from exercise – I used to have sore shoulder joints after weight training (I’m 54). Now, I hit the sauna after weight training and I don’t get sore shoulders anymore. I also seem to recover faster from exercise (my muscles don’t get sore).

2. Increased well-being – I now have a tremendous amount of energy. I seem to need less sleep and I feel full of life. I attribute this improvement to the resultant reduction in body toxins from using the sauna.

3. Decreased body fat – After using this sauna for three months my waist is about one inch smaller than before. This could have been caused by a variety of factors (such as all the extra water I drink in the sauna), but the fact is that I didn’t lose that body fat until after I started using the sauna.

My Clearlight sauna is a first-class product and it works every bit as well as you claimed on your website. Now that I’ve owned and used a Clearlight Sauna, I look forward to purchasing another sauna from you sometime in the future… and this time I’ll buy your top-of-the-line model. I trust your company and product that much, but only because you’ve earned that trust. Thanks, again, for selling me such a terrific sauna!

I have epilepsy and went for my 6 month check-up and the doctor walks in and first thing he says is wow you look great! You have a glow about you and look so healthy. I told him about the sauna and how I am sleeping better and feeling good. He said to keep it up and he wants to get one for himself.

Our Clearlight IR sauna arrived a few days ago. My 17 yr. old son and I put it together in about 30 minutes. It is just beautiful, like a piece of furniture. My whole family has used the sauna several times and it is wonderful. I will admit that I was initially a bit skeptical about having a good sweat at lower temperatures. Now I am totally converted. My wife never liked traditional saunas because they are such a hot and “hostile” environment. She has used our Clearlight Sauna every day since it arrived and loves it.

As a healthcare provider, I have been familiar with the health benefits of IR light for years. I appreciated that Clearlight Saunas didn’t just talk about the potential benefits but provided references for the recent research regarding these benefits.

Thanks again for all your help. It was a pleasure working with you. Your customer service is beyond my expectations. That is something that doesn’t happen very often.
