TheraFlex Wireless Red Light Therapy Belt

Because you’re not tethered to anything during your session. The controller with a 6,000 mAh battery attaches magnetically to the belt, so you can get up, make coffee, or keep working while your session is running. Just like the wired version, it has 120 3-chip LED's with 660 nm red and 850 nm near-infrared light. If you’d prefer more power and no battery, take a look at the wired TheraFlex.

The wireless TheraFlex delivers 143 mW/cm², while the wired one delivers 219 mW/cm². In return, the wireless belt lets you move freely. The wavelengths, LEDs, size, and three modes are the same for both. Since the belt sits directly against your body, we measure on the skin, not at 15 cm as we do with a panel.

No, there are no heating elements in the TheraFlex. A heating belt works with heat; this belt works with light: red at 660 nm and near-infrared at 850 nm, with two 850 nm chips and one 660 nm chip per LED. That light is absorbed in your cells by the mitochondria. Because the LEDs are against your skin, it may feel mildly warm, but the effect researchers are studying comes from the light itself.

No, we don’t promise that. The few small studies on red light and body measurements have mixed results and are too weak to rely on for fat loss. If you want to lose weight, nutrition and exercise remain the foundation. You can wear it on your stomach, for example, for your skin or as a relaxing moment.

Yes, and that’s what most people use the TheraFlex for, too. The belt fastens around your waist, so your entire lower back is exposed to the light while you work or walk around the house. Studies of red and near-infrared light for back and joint problems show that stiffness and pain can decrease and muscles can relax. The 850 nm near-infrared light reaches the muscles around your spine, and you can read more about joint pain and stiffness.

Yes, with the adjustable elastic, the belt also fits around a knee, shoulder, or other joint. Since there’s no cable, you can move around comfortably, although the belt may shift if you move vigorously. Research on photobiomodulation for knee problems shows reduced pain and improved mobility, and many users wear the belt while recovering from an injury. Learn more about recovery after injuries.

That’s possible because you don’t need a power outlet. After your workout, wrap the belt around the muscle group you’ve worked hardest, such as your thighs, lower back, or shoulders, for example while cooling down or in the changing room. Meta-analyses in athletes show that red and near-infrared light can reduce muscle soreness after exercise and speed up strength recovery. Learn all about muscle recovery after training.

If you sit at a desk for long periods, you can wear the belt around your lower back or thighs while you work. Red and near-infrared light releases nitric oxide in your cells, which helps widen small blood vessels, and research shows that this can improve microcirculation in the exposed area. Many users find that an area feels more supple after a session. It’s still just as important to get up and move in between, and you can read more about improving circulation.

Yes. The red light at 660 nm works in the upper layers of the skin, and studies show increased collagen density and smoother skin texture after several weeks of regular use. Place the LED side against your bare stomach or thighs while sitting on the couch or doing something around the house. Choose red light alone or red and near-infrared together, and learn more about skin recovery.

A fully charged 6,000 mAh battery provides about 1.5 hours of light, which is around 3 sessions of 30 minutes. With sessions of 10 to 20 minutes per area, you can get quite a lot done before you need to recharge. For example, you can treat your lower back in the morning and your knee in the evening without having to recharge in between.

The battery is in the controller. Charge it with the cable and plug from the box, and it will be fully charged in about 2.5 hours. You can also charge it with a power bank; charging time then depends on the power bank. If the belt does not seem to turn on, fully charge it first, and keep in mind that you can barely see any light in near-infrared-only mode.

The controller attaches magnetically to the belt, and you can remove it just as easily. Use the compact display to set the mode, brightness, frequency, and timer. Since it sits on the belt, you can feel it when wearing the belt around your neck or lying on your back. If you mainly use the belt while lying down, the wired version with the controller on a cable is often more comfortable.

That is a safety feature, not a defect. If you don’t set a timer, the belt will turn off automatically after about 10 seconds. So choose a session time of between 10 and 30 minutes on the display each time, and it will stay on until the session is over. If it still won’t turn on with a timer set, fully charge the battery first.

Yes, that's what the wireless version is designed for: you can use it at home and on the go, without an outlet. Wear it with the LED side against your bare skin, for example under a loose-fitting shirt at your desk, on the train, or during a break. At 300 grams, you’ll barely feel it. Do not use the belt while driving or cycling.

Gentle movement is fine, such as walking, cooking, or yoga. During sports or vigorous movement, the strap may shift, causing the light to no longer fall on the intended area. Therefore, it’s best to use the belt before or after your workout.

Our recommendation is 10 to 20 minutes per area, 3 to 5 times per week, on bare skin. Set the timer (10 to 30 minutes) on the display for each session, so you don't have to watch the clock while you keep working or move around. Longer or more frequent sessions won't provide additional benefits. Results vary by person, so use it regularly for a few weeks.

There are three modes: red and near-infrared together, red only (660 nm), or near-infrared only (850 nm). If you’re unsure, choose both together. Brightness ranges from 0 to 100 percent, and if you have sensitive skin, start a little lower. The frequency (0 to 1000 Hz) makes the light pulse, but research doesn’t clearly point to a best frequency, so feel free to set it to 0 Hz for continuous light.

The belt uses red and near-infrared light, without UV. Consult your doctor first in these situations:

• for young children, as we do not recommend use without advice from a doctor or specialist;
• during pregnancy, as there is too little research on this;
• if you take medication that makes you more sensitive to light, or have a medical condition.

Do not wear the belt over your eyes or on open wounds.

Remove the controller from the belt before cleaning it. Wipe the exterior with a soft, dry cloth without using any cleaning products. Do not put the belt in the washing machine or submerge it in water. Store the belt and controller in a cool, dry place, away from direct sunlight.

If you order the belt while it’s in stock, it will be delivered to your home in the Netherlands the next day. Delivery to other European countries may take a little longer. A countdown clock next to the order button shows the latest time you can place your order for next-day delivery. If the belt is temporarily available for pre-order, the expected delivery date is shown there instead. Shipping is free.

You have 180 days to try the belt as part of your daily routine. If it’s not right for you, register it in our returns portal to receive a free return label and get your money back. The belt comes with a 2-year warranty against material and manufacturing defects. If any LEDs stop working because of such a defect, we’ll replace the belt free of charge.
