1. The correct wavelengths

What specific wavelengths does the device offer? General specifications like 600-700 nm or 800-1070 nm are not very helpful in making a decision, as these ranges are too unspecific. However, studies show that certain wavelengths can deliver targeted, effective results. We recommend choosing a device that includes both red light and near-infrared light. Research indicates that the following wavelengths, in particular, offer optimal effectiveness and should be included in a high-quality red light therapy device:

Red light: 

Red light penetrates primarily into the surface of the skin, to a depth of about 2 to 3 millimeters. This is particularly effective for treating superficial tissue healing, skin problems, and reducing inflammation.

The best-researched effective wavelengths: 630nm, 660nm, 670nm

Near-infrared light:

Near-infrared light has a penetration depth of approximately 2-5 centimeters, thus reaching deeper tissue. This makes it very suitable for treating bones, joints, and deep muscles.

The best-researched effective wavelengths: 810nm, 830nm, 850nm

Interesting tip:

At heilys, we place great importance on using the correct wavelengths for our devices. Our research team has worked intensively to make our technology as effective as possible. For this reason, our devices incorporate precisely these wavelengths, which can be individually and precisely adjusted. Furthermore, all wavelengths can be used individually or in combination. This way we can ensure that you receive the best possible support.

2. What power output is required?

The power output of a red light therapy device is a crucial factor for the effectiveness of the treatment. It indicates how much light energy actually reaches the skin and is specified in milliwatts per square centimeter (mW/cm²).

To illustrate this: Imagine you're using a flashlight. The more intense the light, the brighter and farther the area is illuminated. A weak flashlight, on the other hand, only shines briefly and dimly. The same principle applies to the power of a red light device – the higher the power, the more efficient the treatment.

Why is high performance important?

• Stronger cell activation : More light energy means that the skin cells are stimulated more intensely, which can lead to better results in healing and regeneration.

• Shorter applications : A powerful device requires less time to deliver a sufficient amount of light energy, thus reducing treatment duration.

• Greater coverage : With higher power, you can position the device further away and still deliver enough energy for effective therapy to larger areas of your body.

What should the power density be? A high-quality red light therapy device should achieve at least 30 mW/cm², ideally closer to 100 mW/cm², at a distance of approximately 15 cm from the skin. These values ​​ensure that the light can penetrate deeply enough to effectively treat both the superficial layers of skin and deeper tissues such as muscles or joints.

If manufacturers don't provide clear information about power density, it's often an indication that the actual performance is insufficient. Reputable suppliers provide accurate information about their devices and explain how the measurements were taken to ensure transparency.

3. Choose the right device size

When choosing a red light therapy device, it's crucial to know what you intend to use it for. Do you primarily want to use the lamp for facial treatments or to address specific conditions such as knee problems or nerve pain? In these cases, a small tabletop or portable device might be perfectly adequate.

However, if you want to treat larger areas of the body or even your entire body, you should opt for a larger panel. While you can use a smaller device and treat several areas in succession, this means you'll need 10-20 minutes per area. For three body parts, that would be almost an hour – and who wants to waste that much time?

The rule of thumb is: Small devices are ideal for targeted, smaller areas, while larger devices are better suited for large-area applications.

• Treatment duration and frequency : Consider how often and for how long you want to use the device. A larger panel reduces treatment time because it covers more area at once.

• Transport and flexibility : If you want to take the device with you regularly, a smaller, mobile model is more practical, even if it takes more time for the treatment.

• Budget considerations : Larger devices are usually more expensive to purchase. Consider whether the higher price is justified for you by the added convenience and time savings.

• Ease of use : Larger panels often offer additional features such as timers, preset programs or app control, which can make the application more convenient.

Considering a larger device can be worthwhile, as many users find that smaller models, while cheaper, often take more time and are therefore used less regularly. A larger panel allows for faster, more comprehensive treatment, increasing the likelihood of more frequent and consistent use.

4. Evaluate the quality of the device.

The quality of a red light therapy device plays a central role in its effectiveness and longevity. High-quality devices are characterized by optimal wavelengths and solid performance, but there are other aspects that are also crucial:

Materials and workmanship

• Durable materials : A reliable infrared lamp should be made of robust materials such as metal housings or high-quality plastic. These materials are resistant and dissipate heat well, contributing to safe and long-lasting use.

• Clean workmanship : Ensure that the device is cleanly manufactured, without sharp edges or wobbly parts. High-quality connections and a stable construction ensure a long service life and high safety during use.

Certifications and safety standards

• Safety certificates : Certifications such as TÜV, RoHS, or FDA approval in the USA are important indicators of a device's quality and safety. They ensure that the device meets strict standards and has been thoroughly tested to guarantee safe and effective use.

5. Customer service and warranty services

The quality of customer service and warranty terms are crucial indicators of a manufacturer's reliability. Here are some aspects you should consider:

guarantee

• Warranty period : A long warranty period demonstrates the manufacturer's confidence in the product's quality. A minimum of one year's warranty should be standard, but ideally two or more years.

• Scope of coverage : The warranty should cover not only manufacturing defects, but also defects that were not caused by user error.

• Simple handling : The process for claiming under the warranty should be as straightforward as possible so that you receive quick support if the device is defective.

Customer service

• Accessibility : Customer service should be reachable through various channels, such as telephone, email or live chat, and ideally respond quickly.

• Friendliness and competence : Good customer service answers questions not only in a friendly but also competent manner, and offers quick solutions to problems.

• Additional support : Many manufacturers offer additional advice on the optimal use of the device or provide up-to-date information on red light therapy.

• Informative website : A comprehensive website from the manufacturer with instructions, frequently asked questions, scientific information and application examples is also a sign of good customer service.

6. Check the reviews

Customer reviews are a valuable source of information for assessing the actual performance and reliability of a red light therapy device. These testimonials provide important insights into the product's effectiveness, build quality, and lifespan. Pay particular attention to reviews that offer detailed information on the device's use and benefits.

The quality of customer service can also be clearly gauged from customer reviews. Experiences regarding the accessibility, responsiveness, and competence of the support team can show you how the manufacturer reacts in case of problems. Reliable customer service that receives positive feedback is a good indicator of the provider's trustworthiness.

Even if a product doesn't have many reviews yet, other aspects, such as the quality of the website or the available information on optimal use, can help you assess the manufacturer's trustworthiness. A well-designed website with helpful tips and comprehensive information is an indicator that the manufacturer cares about its customers.
