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

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

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/

 

Happy St. Patrick’s Day—whether you’re going fact or legend, it’s a great excuse to celebrate!

St. Patrick is a mix of solid historical fact and popular myth/legend that grew over centuries. He was a real historical figure—a British-born missionary (likely from what is now Scotland or northern England/Wales area) who lived in the 5th century (roughly 385–461 AD). His birth name was probably Maewyn Succat, and he became known as Patricius (Patrick) later. He wrote two surviving documents: his Confessio (Confession) and a letter to Coroticus, which are the main primary sources about his life. These confirm he was kidnapped by Irish raiders as a teenager, enslaved in Ireland for about six years (herding sheep), escaped, trained for the church, and returned as a missionary bishop to convert the Irish to Christianity. He wasn’t the first Christian in Ireland—some communities already existed—but he’s credited with major missionary work and is the patron saint of Ireland.

Many beloved St. Patrick’s Day traditions and stories are myths or later embellishments: Myth: He drove the snakes out of Ireland. Completely legendary. Ireland has had no native snakes since the last Ice Age (about 10,000+ years ago)—the post-glacial island was isolated, and snakes never recolonized it. The “snakes” story symbolizes driving out paganism or “evil”  but it’s not historical. Myth: He used the shamrock to explain the Holy Trinity. This is a charming story, but it doesn’t show up in Patrick’s own writings or early biographies. While the shamrock (a three-leaf clover) became a symbol of Ireland and St. Patrick’s Day, the Trinity analogy is probably a later invention. Myth: St. Patrick was Irish by birth. No—he was Romano-British, captured and brought to Ireland against his will. Other common myths: Green wasn’t always the color associated with him or the holiday; massive parades and “wearing of the green” became big in America first; he didn’t drink green beer or eat corned beef and cabbage, those are more modern Irish-American traditions. In short: The man himself is fact—a brave, devout missionary who helped spread Christianity in Ireland. But many of the fun, magical tales attached to him are myths.
