LED lighting
In 2007 high power, black-body locus LED lights where a new thing. The patented Blender light used these in a bi-color configuration to make the first practical high power, flicker-free, virtual-single-source array light for film and video. Still a leader in output for size, the first units were made by hand in my workshop.
