A few years ago all we needed to produce light from electricity was a few wires including one that got (intentionally) very hot. From there we moved to passing electricity through a gas with the help of a wirewound ballast and a little thermal switch. In short order we have seen electronics overwhelm lighting. Starting with high-frequency ballasts for fluorescents and metal halide gear. Over the past decade or so we have seen them extend to being the very source of light.
