A few weeks back, I wrote at length about LED strip lighting. Originally, that story had been about more than just LED’s—I’d wanted to cover the entire world of flexible lighting. Since addressable LED lighting proved to be more than enough glowing awesomeness for one article, I never got around to talking about another fun, affordable way to trick out virtually any project: EL wire.
What is EL wire? Electroluminescent wire—more commonly known as EL wire—is probably the simplest solution for adding lighting to a project. It’s a thin, flexible wire that (when powered) gives off a bright, even glow along its entire length. In appearance, it’s not unlike a chemical glowstick or a neon sign. It’s waterproof, stays cool, can be cut to whatever length you want, and as long as the soldered joints are properly insulated, it won’t shock you. All those qualities (and its more-than-passing resemblance to the piping on the Tron outfits) make it a very popular choice for light-up costumes, clothing and accessories. Because it’s very energy efficient, EL wire is also used as accent lighting indoors and in vehicles.
EL wire requires an alternating current source, which means that you’ll need to connect it to a transformer—usually a little battery-powered box you can tuck away someone on your project or in your costume. Greater lengths of EL wire require more power.
