Cell Glow recommends: RLT describes the application and LED the light source: a Cell Glow panel is therefore an LED device for targeted red/NIR sessions. Compare wavelengths, measured output and controls, not just the word 'LED'.
Which terms are interchangeable?
An LED can emit blue, amber, red or near-infrared light. Lasers are also being investigated in photobiomodulation. The relevant comparison is therefore not just 'LED or red', but which wavelength, dose, surface area and application a device delivers. For example, blue LED treatment for acne answers a different question than red light for fine lines.
Is laser better than LED?
A laser beam and LED panel distribute light differently. This does not automatically make results from a laser study valid for a home panel. The best source of evidence is research with a comparable device, the same purpose and measurable outcomes in humans. A technical term on a package is not a clinical result.
How do you read the specifications?
Find a list of exact wavelengths, measured light intensity at the recommended distance, session duration and safety instructions. Also ask whether red and NIR can be adjusted separately if that is relevant to you. Don't let the marketing term 'full spectrum' do not take the place of verifiable figures.
