My LED light strips came tonight. I soldered the wire harnesses up and taped the strips above my chronograph's sky screens. I set up the chronograph in the living room, turned out the lights and turned on the LED's. Seems to work well with spit balls from a straw. I can fire a spit ball anywhere from 65 FPS to 101 FPS. I am anxious to try bullets this weekend, sure hope I have crappy lighting conditions.
