The first outdoor night baseball game was played in Massachusetts in 1880, when event organizers erected 36 lamps to generate approximately 90,000 foot-candles of light onto the playing field. Sports promoters quickly came to appreciate how illuminating playing fields would open their sports to a broader audience that would not otherwise be able to attend events during the day when they were working. In the more than 100 years since this first event, metal halide lighting systems have been the standard for almost every night time sports activity, not just for baseball and football, but also horse-racing, skiing, and golf.
