<p class="MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri","sans-serif"; color:#1F497D">Any light is damaging if the exposure is long enough. Visible light is what causes fading.</span></p>
<p class="MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri","sans-serif"; color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri","sans-serif"; color:#1F497D">Some LEDs are at least free of any measureable UV radiation. The UV is what does structural damage to the hair.</span></p>
<p class="MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri","sans-serif"; color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri","sans-serif"; color:#1F497D">You have to test the LEDs for UV output. The Cree lamps we have been using at NMNH have no detectable UV, using a calibrated Elsec 765 meter.</span></p>
