A panel with more wavelengths only helps if each wavelength delivers meaningful energy. Independent reviewers note that &#8220;bonus&#8221; wavelengths added for marketing often carry almost no usable power, so the count on the box can be higher than the number of wavelengths actually doing anything.<\/p>\n    <h3>Which wavelengths matter most in red light therapy?<\/h3>\n    <p>The most established wavelengths sit in the red range (around 630\u2013660nm) and the near-infrared range (around 810\u2013850nm). These are the two bands with the most photobiomodulation research behind them. Additional wavelengths may have specific uses, but red and NIR are the core of most credible panels.<\/p>\n    <h3>Why do brands add extra wavelengths like 480nm or 1064nm?<\/h3>\n    <p>Partly for genuine reasons and partly for marketing. Some wavelengths have specific applications, but a higher wavelength count also looks impressive on a spec sheet. The key question is how much power each wavelength delivers \u2014 a wavelength present in name only, with a few token LEDs, adds little beyond the number on the box.<\/p>\n    <h3>How do I know if a multi-wavelength panel is legitimate?<\/h3>\n    <p>Ask for the power or irradiance contribution of each wavelength separately, not a single combined figure. A legitimate multi-wavelength panel can show meaningful output per wavelength. If a brand only gives a total, or can&#8217;t break it down, the extra wavelengths may be present in token amounts.<\/p>\n    <h3>Is a dual 660nm and 850nm panel enough?<\/h3>\n    <p>For most purposes, a well-built dual-wavelength panel delivering strong 660nm and 850nm output covers the two most-researched bands. A carefully designed dual panel with high output per wavelength often outperforms a multi-wavelength panel that spreads weak output across many wavelengths.<\/p>\n  <\/div>\n\n  <div class=\"cta\">\n    <p class=\"cta-h\">Get the output per wavelength, not just the count<\/p>\n    <p>Sourcing panels for your brand?
