Providing, measuring and demonstrating highly effective uplighting

A method for measuring, demonstrating, or verifying uplight relative to an illuminated sports field comprising:

• a. positioning an object at a known trajectory or to a known height relative to the sports field;
• b. measuring a characteristic of the uplight relative the object;
• and
• d. evaluating uplighting performance relative to the illuminated sports field from the determination.

A system for measuring, demonstrating, or verifying uplight relative to an illuminated sports field comprising:

• a. a wide area lighting system including plural solid state light sources in each of plural luminaires positioned and aimed to provide illumination and uplight relative to the sport field;
• b. a launcher or an elevator adapted to either propel an object at a known trajectory or suspend an object to a known height relative to the sports field;
• b. a sensor adapted to measure a characteristic of the uplight relative the object;
• and
• d. a processor adapted for communication with the sensor and having programming to evaluate uplighting performance relative to the illuminated sports field from the sensor measurements.
