This is an ordinary 48-inch florescent tube being excited by sparks from the improved junk box coil running at 1080VA. The tube is taped to a length of plastic pipe to act as an insulated handle. This is captured video. The little VHS-C camera is on a tripod. I'm out of the frame to the right holding up the tube. Spark contact isn't necessary for light production. The tube glows if it is within 8 feet of the operating coil!
