Red Light Therapy Questions

All Red Sun devices offer both wavelengths for optimal results.

You can switch between red light, near infrared light, or both on every of our models.

Delivered at 660nm, red light is readily absorbed by surface tissues and cells, leading to enhanced skin health and healing.

Delivered at 850nm, near infrared (NIR) light is invisible to the human eye, and penetrates into deeper tissues, leading to enhanced recovery and inflammation support.

Red Sun uses only the red and near infrared wavelengths that are clinically-proven to be safe and effective. However, we always recommend consulting with your healthcare provider for specific questions about your health condition(s). 

Red light therapy has been rigorously studied and tested for decades, from NASA to the leading medical research institutions in the world. In 2013, several of the world’s leading dermatologists and clinical researchers from Harvard Medical School and MIT published a peer-reviewed meta-analysis noting red light therapy’s “non-invasive nature and almost complete absence of side effects.” Red Sun uses only the red and near infrared wavelengths that are clinically-proven to be safe and effective. However, we always recommend consulting with your healthcare provider for specific questions about your health condition(s).

Red light therapy has been studied extensively and is proven to be effective by thousands of peer-reviewed medical studies and clinical trials. The studies have shown extremely positive results, and an almost total lack of side effects or health risks associated with it. We encourage our customers to do a search on PubMed for peer-reviewed medical studies and clinical trials regarding red and near infrared light therapy.

“Red light therapy” refers to treatments from LEDs that deliver wavelengths of natural red and near infrared light. Red light therapy does not rely on heat, a major difference between natural light treatments and heat-based modalities like an infrared sauna, traditional sauna, or other type of heat therapy. Red light therapy describes natural light treatments that deliver the same therapeutic red and near infrared wavelengths as natural sunlight. This differs from artificial light treatments like tanning or bright light therapy from a light therapy lamp, light box, or happylight. Red light therapy may also be referred to as the following terms: RLT, photobiomodulation (PBM), phototherapy, LED therapy, LED light therapy, low-level laser therapy or low level light therapy (LLLT). 

Red light therapy is a non-invasive treatment that delivers natural wavelengths of light to our bodies. When these specific, concentrated wavelengths of light are absorbed by photoreceptors known as cytochrome c-oxidase on our cells, they stimulate the mitochondria within the cells to create more energy which is used to power all necessary functions in our bodies. Best of all, red light therapy treatments are quick, convenient and can be done in the comfort of your home and are now more affordable than ever before. In the past, it was thought that red light therapy could only be achieved using high powered, expensive lasers. In recent years, studies have shown that LEDs are every bit as effective as those expensive, inaccessible lasers. As a result, the benefits of red light therapy are easier to experience now than ever before.

Red Sun Devices Questions

Frequentely asked questions about technicalities of the hardware of the Red Sun modular devices. 

We launched our red light therapy products because we noticed that most of the panels on the market today are overpriced and underpowered. We believe that the benefits of red light therapy should be able to be experienced by everyone, not only people who have a lot of money to spend. Our panels are manufactured in an FDA approved facility and are backed by a 2 year warranty. They're high powered in terms of irradiance and low in EMF output, and have cooling fans built in to ensure the device stays cool and safe. Best of all, we don't charge an arm and a leg for our devices because we want to make our devices accessible to more and more people who deserve to experience the benefits of red and near infrared light therapy.

A big one! LEDs are the most effective technology for controlling the wavelength and direction of light therapy. They also allow for the delivery of high-intensity output with minimal heat. They're by far the most efficient source for light therapy and Red Sun Therapy only uses industry leading 5w LEDs for optimal results. 

Beam angle is a measurement of how light is distributed from a light source. Some LED light manufacturers use a wide beam angle of 90 degrees, which causes the power density to reduce over distance, compared to a narrower beam angle of 60 degrees. If you are planning to use red light therapy to target a larger area of your body by positioning yourself further away, a narrower beam angle is highly recommended. Red Sun uses an optimal narrow beam angle of 60 degrees to ensure therapeutic power density at further distances.

All Red Sun Therapy devices use red 660 nm and near-infrared (NIR) 850 nm.

Near-infrared light is an invisible healer.

Unlike red light, near-infrared light is nearly invisible to the naked eye. When running both wavelengths at the same time, the near-infrared LEDs may appear off. This is due to the contrast of the red and near-infrared, as the red appears much more luminous to our eyes. Rest assured the LEDs are active and delivering a powerful dose of 850 nm. If the red light LEDs are working, the near infrared LEDs should be as well. To test this on your device, turn only the NIR switch on. You should see a very faint illumination of the NIR LEDs. 

We believe anyone should have access to the benefits of red and near infrared light therapy. We don't spend exorbitant amounts of money on advertising or celebrity endorsements. Instead, we keep our costs low and pass the savings along to our customers.

All electric devices have some degree of electromagnetic field, due to the nature of their power source. The EMF output of our devices comes in at 0.0 µT at 6" (which is our recommended minimum treatment distance). This means that at 6" and beyond, you are receiving zero EMF exposure when doing a red light therapy treatment with our device.

Red Sun devices are engineered to have low EMF levels. However, anything with an elextric current running through it is going to generate some electromagnetic field. At the recommended usage distance of 6-12 inches, our devices emit no detectable levels of EMF.

We offer a full 60 day return period, so you get to try your device out at no risk. We don't charge any restocking fees. If you are not happy with your light for some reason, send it back for a full refund. Furthermore, our products come with an automatic 2 year warranty. If your device stops working or suffers some sort of mechanical failure within 2 years of your purchase, just reach out to us with your order number and we'll either replace or repair your device free of charge.

Usage Questions

Frequently asked question from users about the daily use of Red Sun products. 

It's actually quite simple. Just plug it in, turn it on, and let the red and near infrared light wavelengths shine on your body for somewhere between 2 and 15 minutes, depending on distance from the panel and your specific goals! The recommended distance from the divice is between 6" and 12". We recommend your work your way up to 6" and start at 12" from the device for the most safe and optimal results. 

It varies by person and how consistent you are with treatments. Many users report acute energy and cognitive benefits with each use. Many see benefits like reduced inflammation and muscle soreness in a matter of days, or weeks. More full-body health benefits like skin health, fat loss, and other long-term improvements may take 2-3 months of consistent daily use.

More doesn’t always mean better! Treatments longer than 15 minutes won’t necessarily lead to greater benefits because your cells can only absorb so much light. The great thing about a Red Sun is that you can obtain the same benefits in less time versus other products on the market. 5-15 minutes per day is all you need. 

The surface may get a little warm, however, there is a built in cooling fan that is going to keep it from getting very warm. With that being said, the device is very high power and is has the ability to cover a large surface area, so you shouldn't need to be very close to the device to get an effective treatment. We recommend about 6-12 inches away from the device in general. You should feel only a very faint heat from the 6" distance that is the maximum recommended proximity from the device. At 12" from the device, you should not feel any heat whatsoever.

Wearing eye protection is not necessary but we do include eye protection in case you feel more comfortable doing so.

We recommend wearing safety goggles during the treatment sessions. As such, Red Sun provides one pair of safety goggles with each device. Our Red Sun LED bulbs are very powerful and bright. If you have any eye problems, please consult with a healthcare professional before using red light therapy. 

It depends on what you're looking to treat. For skin and topical treatments, the recommended sweet spot of dosing for a given treatment area is roughly between 3J and 15J. For deeper tissues, such as muscles, ligaments, or bone, the sweet spot for a given treatment area is between 10J and 50J of light. Our panels give you roughly 5J of light per minute of use from 6 inches away. This varies slightly from the smaller panels to the larger panels, but it will give you a close enough idea of how to dose your treatment at 6 inches distance.
