Qualite Sports Lighting is a sports lighting manufacturer headquartered in Hillsdale, Michigan, in business more than 35 years as a lighting partner for high schools, colleges, parks and recreation departments, and professional franchises. Its flagship product, the Q-LED GameChanger, is a high-performance LED system built for any sports venue from youth fields to professional stadiums, using a 50,000-hour lamp life (versus 3,000 to 5,000 hours for older metal halide systems), instant-on capability instead of the 40-minute warmup of traditional stadium lighting, and a 25-year or 10,000-hour comprehensive warranty covering parts and labor. Pickleball and other court facilities are part of Qualite’s broader lighting portfolio, alongside football, baseball, and soccer venues, with color-customizable fixtures and thousands of completed installations nationwide. The Edison Awards named the Q-LED GameChanger a gold-medal innovation winner. Office hours run weekdays 8 to 5, closed weekends.
