I finally finished the 1000W xenon searchlight project that I started earlier this year. The power supply is a slightly modified arc welder coupled with an automotive ignition coil for the starting pulse.
This is the searchlight's beam shooting skyward behind a large pine tree in my back yard. The beam is very difficult to capture on video.
