Hello, I'm Amkgp. An edit that you recently made to Timeline of lighting technology seemed to be a test and has been removed. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Amkgp (talk) 08:48, 28 April 2020 (UTC)
