Hello, I'm Elfabet. I noticed that you added or changed content in an article, LED art, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. ''The external link you added is not a reliable, neutral, secondary source, as such it was removed. It also seems there may be a violation of WP:ADVERTISEMENT, and/or a conflict of interest. Please do your best to contribute to Wikipedia constructively~ Cheers!'' Elfabet (talk) 21:27, 14 June 2019 (UTC)
