US Open Set Up for Dark Sky-Friendly Outdoor Lights by Adithi Ramakrishnan

William Attardi on August 22, 2025

When the court lights flicker on at the U.S. Open, tennis stars shine under illumination designed to cut light pollution.  The U.S. Tennis Association swapped metal halide bulbs for shielded wedge-shaped LED lights. The complex’s 17 tournament courts and five practice courts were approved as dark sky-friendly last year. Most arenas make the change during scheduled maintenance and renovation, working with sports lighting company Musco. The company lights over 3,000 venues a year including college football stadiums, tennis courts and rail yards. US Open Set Up for Dark Sky-Friendly Outdoor Lights – tEDmag

Pickleball & Tennis Court Illumination by U.S. Architectural Lighting

William Attardi on May 2, 2025

U. S. Architectural Lighting recently introduced Baseline – Pickleball & Tennis Court Lighting. Designed specifically for the court, Baseline uses a Type IV CL precision optic designed especially to meet IESNA / USA Pickleball / USTA Standard Performance Criteria for court photometrics. The luminaires distribute uniform light across the court surface without creating hot spots. To minimize glare, the light is directed at a low angle onto the court surface avoiding direct glare into the eyes of the players to prevent discomfort or distractions during play. The Baseline is available in five sizes in wattages from 85W to 550W, with up to four fixtures per pole, in parallel assembly arrangements, allowing a wide range of lumen packages. https://usaltg.com/product/bas/

 

The Genesis of the U.S. Space Force – On December 20, 2019, President Donald Trump signed the National Defense Authorization Act (NDAA) for Fiscal Year 2020, officially creating the United States Space Force, a new and independent branch of the U.S. military. The establishment of the Space Force marked a historic shift in how the U.S. views and manages its military operations in space, reflecting the growing importance of space as both a domain of strategic competition and national security. The Space Force is tasked with ensuring the U.S. maintains its superiority in space, focusing on both the defense of space assets and the development of offensive capabilities. Its mission includes:

  1. Space Operations: Overseeing space-based systems, such as satellites, that provide essential services to the U.S. military, including communication, reconnaissance, and missile defense.
  2. Space Security: Protecting U.S. space infrastructure from threats, including anti-satellite weapons, cyberattacks, and other potential forms of disruption by adversarial nations.
  3. Space Research and Development: Developing and deploying cutting-edge space technologies, including space-based defense systems, that ensure the U.S. maintains an edge in space exploration and military operations.
  4. Supporting National Defense: Integrating space capabilities into broader national defense strategies, ensuring that U.S. forces can operate effectively in space as part of a multi-domain approach to warfare.

The Space Force is designed to streamline and strengthen the U.S. military’s space operations, which were previously under the purview of the U.S. Air Force. By separating space operations into a distinct branch, the government hoped to increase focus on space as a critical area of national defense and enhance the U.S. military’s ability to respond to emerging threats.
