TheraFlex Wired Red Light Therapy Belt

Because it delivers the most power of all our belts: 219 mW/cm², measured on the skin. It works plugged into a wall outlet or via USB, so there’s no battery running out halfway through, and you can treat multiple areas in a row. It’s also the only version with a breathing mode. If you want to move around freely during your session, the wireless TheraFlex is a better fit.

The wired belt delivers 219 mW/cm², and the wireless one delivers 143 mW/cm², both measured at contact distance because the belt sits directly against your body. More power means more light energy reaches your skin in the same session time. The LEDs, wavelengths (660 and 850 nm), and size of 45 x 20.5 cm are the same for both. The recommendation of 10 to 20 minutes per area remains the same.

No. A heating pad or infrared lamp warms your skin, while the TheraFlex has no heating elements and uses LED light at 660 nm (red) and 850 nm (near-infrared). This light is absorbed by the mitochondria in your cells, which is the focus of research into photobiomodulation. A slight warming sensation on your skin is normal because the LEDs are in direct contact with your skin.

It depends on what you want to target. The belt sits directly against your skin and targets one area at a time, such as your lower back, a knee, or your shoulder, while you sit or lie down. You use a panel from a distance, and it targets a larger area of your body with more wavelengths at once. If you want to target your entire back or several areas at once, take a look at the ATP Pro panels.

Yes, that’s one of the most comfortable ways to use it: the belt lies flat around your lower back, with the controller beside you. Research into red and near-infrared light for back and joint problems shows that it can reduce stiffness and pain and help relax muscles. At 219 mW/cm², this is our most powerful belt, and the 850 nm near-infrared light penetrates into the muscles around your spine. Read more about joint pain and stiffness.

Fasten the strap around your knee or shoulder using the adjustable elastic and sit or lie down comfortably so the joint can relax. Studies on photobiomodulation for knee problems show reduced pain and improved mobility, and many users use the belt to support recovery after an injury. If you are undergoing treatment, consult your physical therapist or doctor before use. Read more about recovery after injuries.

Yes, and that’s where the wired version comes in handy: without a battery, you can move straight from your thighs to your calves, lower back, or shoulders. Treat each muscle group for 10 to 20 minutes, then reposition the belt. Meta-analyses of athletes show that red and near-infrared light can delay muscle fatigue, reduce post-exercise soreness, and speed up strength recovery. Learn all about muscle recovery after training.

The light releases nitric oxide in your cells, a substance that helps widen small blood vessels. Research shows that this can improve microcirculation in the illuminated area, helping oxygen and nutrients reach your muscles and tissue more effectively. After a session, an area often feels more supple, even though the belt does not use heat. Learn more about improved blood circulation.

For the skin, yes: 660 nm red light works in the upper layers of the skin, and studies show higher collagen density and firmer skin texture after several weeks of regular use. Place the band on your stomach or thighs while you lie down and relax. We don’t promise weight loss or fat loss, as the small studies on this are not convincing. Visit our page on skin recovery.

The box includes a 12V wall adapter, which you can use to plug the belt into a wall outlet. You can also use it with a USB port that supplies 5V at 3 to 4 A, but never use a 12V USB adapter. The controller is attached to a cable that plugs into the band’s DC port, so disconnect it when storing or cleaning the band. A power bank is not included.

Yes, it doesn’t have a battery, so the belt keeps working as long as it’s plugged in. That’s useful if you want to treat multiple areas one after another, for example, your lower back first and then your knee. The recommended time per area is still 10 to 20 minutes, and the timer goes up to 30 minutes. Using it longer on the same spot won’t provide any additional benefit.

A USB port or USB adapter that delivers 5V at 3 to 4 A. Many laptop ports and small phone chargers supply less current than that. Never use a 12V USB adapter, and if in doubt, use a 12V wall adapter.

Because the controller is on the cable and not on the belt, the belt lies flat and comfortably under your back or around your neck. Place the controller next to you, choose your settings, and set the timer; the session will stop automatically. That way, you can truly relax without watching the clock. Position the cable so it doesn’t get caught when you turn over.

In breathing mode, the light gently pulses. Many people turn on this setting when they want to relax during their session, for example, in the evening on the couch. This mode is only available on the wired TheraFlex.

Use the belt for 10 to 20 minutes per area, 3 to 5 times a week, on bare skin, because clothing blocks a lot of light. The fact that it has no battery does not mean longer is better: stick to this time for each area. After using it regularly for several weeks, you can better assess how it works for you, as results vary from person to person.

On the display, choose from three modes: red and near-infrared together, 660 nm red only, or 850 nm near-infrared only. Using both together is a good starting point. Set the brightness from 0 to 100 percent, and start lower if you have sensitive skin. Pulse mode (0 to 1000 Hz) is optional, and since research shows no clear preference for a particular frequency, feel free to choose 0 Hz for continuous light.

No, that’s how it’s supposed to work. Without a timer set, the TheraFlex automatically turns off after about 10 seconds as a safety measure. Press the settings button until you reach the timer, then choose a time between 10 and 30 minutes. The belt will stay on until your session is over.

Red and near-infrared light do not contain UV, but in a few cases, you should consult your doctor first. For young children, we do not recommend use without advice from a doctor or specialist. We do not recommend use during pregnancy because there is not enough research, and if you are taking medication that makes you more sensitive to light or have a medical condition, ask for advice first. Do not place the band over your eyes or on open wounds.

First unplug it from the wall outlet or USB port and disconnect the controller from the band. Wipe the fabric with a soft, dry cloth, without using any cleaning products. Do not put the band in the washing machine or submerge it in water. Coil the cable loosely and store everything in a cool, dry place, away from prolonged exposure to sunlight.

If the wired belt is in stock, it will be delivered the day after you order in the Netherlands. If you order from another European country, it may take a little longer. Next to the order button, you’ll see a countdown showing the latest time to order for next-day delivery. If the belt is temporarily available for pre-order, you’ll find the expected delivery date there. Shipping is free.

The TheraFlex comes with a 2-year warranty against material and manufacturing defects under normal use. If, for example, some of the LEDs stop working due to such a defect, we’ll replace the belt free of charge. You also have 180 days to try it at home, and if you want to return it, you’ll get a free return label through our returns portal and your money back. You can find all the terms and conditions under Returns & Warranties.
