Hello, I'm C.Fred. I wanted to let you know that I removed an external link you added to the page Light-emitting diode, because it seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you. —C.Fred (talk) 17:19, 24 May 2013 (UTC)
