Mt. San Antonio College’s (Mt. SAC) Hilmer Lodge Stadium was built in 1948 and earned worldwide recognition after the Mt. SAC Relays developed into one of world’s largest track meets. This encouraged the college to pursue a complete facility upgrade that would include new LED lighting to equip the stadium to host other elite-level track and field and cross-country competitions. School officials’ top priority was to improve light levels and visibility while minimizing spill and glare in order to satisfy the International Association of Athletics Federations’ (IAAF) lighting standards and preserve darkness for the surrounding community.
