I worked on the light fixtures for the US Insurance Institute for Highway Safety, vehicle research center. http://www.iihs.org/iihs/about-us/vrc

These lights were 72,000 watts each, with a total of around three-quarters of a million watts of lights in the crash hall. (Almost as as much power as the German sun installation.) High speed cameras need a lot of light.

I've stood in front of one of the lights in protective gear - but the heat still just goes through your body.

The first time the IIHS lights were turned on it blew a power substation 20 miles away.
