EL Wire, also known as Electroluminescent wire is a stiff wire core coated with phosphor and then covered with a protective PVC sheath. When an AC signal is applied to it, it glows an aqua (blue green) color. It looks a little like thin neon. Very bendable, it keeps its shape and you can curl it around your finger. Its an easy way to add some glow to a project, not as bright as LEDs but uses a lot less power! https://elecena.pl/product/17497847/aqua-electroluminescent-el-wire-2-5-meters 2021-04-06 https://elecena.pl/product/17497847/aqua-electroluminescent-el-wire-2-5-meters 2021-05-22
