What exactly is "unseen blue light"?
- betaby 10y agoIt's perfectly "seen". LED without filter has blue spike in spectrum. http://www.ledsmagazine.com/content/dam/leds/PrintArticles/volume-12/issue-10/1510LEDs_F6f1.png http://www.ledsmagazine.com/content/dam/leds/PrintArticles/v...
- jackyinger 10y agoI think they mean that there is a lot of blue light emitted, but it is not super obvious because they emit longer wavelength light as well (reds & greens).
