The Ellumiglow Eco-EL Wire is a cost effective Electroluminescent Wire that is great for costuming applications and portable use projects. This more pocket-book friendly wire provides new colors compared to the standard EL Wire Ellumiglow has been known for, while still providing a great quality EL Wire. The diameter of the jacketing is 2.6mm and has a 0.5mm core, compared to the standard EL Wire core of 0.7mm. This makes the Eco-series a bit more flexible, and doesn't hold its shape quite as well as the standard, which can have different uses for each series. Many people love the new colors, and it doesn't hurt to get a little more for your money these days. If comparing brightness's between the two, the standard wire is still brighter, but does consume more power.
