1. The Right Wavelengths

What specific wavelengths does the device offer? General specifications like 600-700 nm or 800-1070 nm aren't really helpful for decision-making, as these ranges are too unspecific. However, studies show that certain wavelengths can deliver specifically effective results. We recommend choosing a device that includes both red light and near-infrared light. Research results indicate 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 primarily penetrates the surface of the skin, about 2 to 3 millimeters. This is particularly effective for treating superficial tissue healing, skin problems, and combating inflammation.

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

Near-Infrared Light:

Near-infrared light has a penetration depth of about 2-5 centimeters, thus reaching deeper tissues. This makes it very suitable for treating bones, joints, and deeper 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 adjusted INDIVIDUALLY and precisely. In addition, all wavelengths can be used individually or together. This way, we can ensure you receive the best possible support.

2. What Power is Needed

 

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 hits the skin and is specified in milliwatts per square centimeter (mW/cm²).

To illustrate: imagine using a flashlight. The more intense the flashlight's beam, the brighter and further the area is illuminated. A weak flashlight, however, only shines briefly and faintly. The same applies to the performance of a red light device – the stronger the power, the more efficient the treatment.

Why is high power important?

• Stronger Cell Activation: More light energy means that 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, so treatment duration can be reduced.

• Larger 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 reach at least 30 mW/cm², but ideally towards 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 superficial skin layers and deeper tissues such as muscles or joints.

If manufacturers do not provide clear information on power density, it is often an indication that the actual power is insufficient. Reputable providers give precise information about their devices and also explain how measurements were carried out to ensure transparency.

3. Choosing the Right Device Size

 

When selecting a red light therapy device, it's crucial to know its intended purpose. Do you primarily want to use the lamp for facial applications or to treat specific ailments like knee problems or nerve pain? In these cases, a small tabletop or portable device might be perfectly sufficient.

However, if you want to treat larger body areas or even the entire body, you should opt for a larger panel. While you could use a smaller device and treat several areas sequentially, this means you'd need 10-20 minutes per spot. For three body parts, that would be almost an hour – and who likes 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 extensive applications.

• Treatment Duration and Frequency: Consider how often and how long you want to use the device. A larger panel reduces treatment time by covering 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 treatment.

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

• User-friendliness: Larger panels often offer additional features like timers, preset programs, or app control, which can make use more comfortable.

Considering a larger device can be worthwhile, as many users find that smaller models, while cheaper, often take more time and are thus used less regularly. A larger panel allows for faster, holistic treatment, which increases the likelihood of it being used more frequently and consistently.

4. Assess the Device's Quality

 

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 decisive aspects:

Materials and Workmanship

• Durable Materials: A reliable red light device should be made from robust materials such as metal housings or high-quality plastic. These materials are resistant and dissipate generated heat well, contributing to safe and long-lasting use.

• Clean Workmanship: Ensure 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 applications.

5. Customer Service and Warranty Services

 

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

Warranty

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

• Scope of Coverage: The warranty should cover not only manufacturing defects but also defects not caused by user error.

• Easy Processing: The process for claiming warranty should be as uncomplicated as possible so that you receive quick support if the device is defective.

Customer Service

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

• Friendliness and Competence: Good customer service not only answers questions friendly but also competently, and offers quick solutions to problems.

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

• Informative Website: A comprehensive manufacturer website 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 effectiveness, craftsmanship, and lifespan of the product. Pay particular attention to reviews that offer detailed insights into the application and benefits of the device.

The quality of customer service can also be well-gauged from customer reviews. Experiences regarding accessibility, responsiveness, and competence of support can show you how the manufacturer reacts in case of problems. Reliable customer service that receives positive feedback is a good sign 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 useful tips and comprehensive information indicates that the manufacturer cares about its customers.
