IES stands for Illuminating Engineering Society. The IES standard file format was created for the electronic transfer of photometric data over the web. It has been widely used by many lighting manufacturers and is one of the industry standards in photometric data distribution. An IES file is the measurement and distribution of a lights intensity. You can think of it as digital instructions for how a 3d light should be represented.
If you use IES lights in your visualizations, why not try the free library.
Daniel Tal even references it in his book, Rendering in Sketch-up. Daniel is an amazing resource as a landscape designer, SketchUp guru, author and teacher. Find Daniel's book on amazon.
