Cell Glow recommends: Choose a trustworthy RLT device by verifiable measurements, clear wavelengths and accessible service. Cell Glow lists Custom specifications by model and helps you choose for the area and intended use, rather than an empty 'best panel' claim.
What data do you want to see?
Look for a clear model number, wavelengths, measuring distance at the stated irradiance, power supply, manual, return address and warranty conditions. Ask how the light output is measured. A separate number in mW/cm² without distance or measuring method is difficult to compare. Photos of an attractive panel also do not say anything about the actual dose.
What does and does not say a quality mark?
In the EU, CE obligations apply to applicable product categories. For medical devices, the meaning depends on the risk class and intended use; some categories use self-certification. 'FDA approved' is incorrect language used in many American lighting devices. None of these labels automatically prove that every health claim for this specific device is correct.
What red flags are there?
Be careful with promises of cures for various diseases, hidden company data, unverifiable testimonials or a price that seems to only apply with a countdown. Choose a seller who answers questions about maintenance and defects in concrete terms.
