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/

 

 

What Are Stablecoins and How Do They Work?

Stablecoins are less volatile than other cryptocurrencies (like Bitcoin) and due to crypto assets’ inherent instability, stablecoins are growing in popularity with both crypto and traditional markets. Stablecoins are a type of crypto asset, but one that offers a way to bridge the gap between fiat currencies like the U.S. dollar and cryptocurrencies. Because they are price-stable digital assets that behave like fiat but maintain the mobility and utility of cryptocurrency, stablecoins are a novel solution to crypto volatility: price stability is built directly into the assets themselves.  There are four primary stablecoin types, identifiable by their underlying collateral structure: fiat-backed, crypto-backed, commodity-backed, and algorithmic stablecoins.  What Are Stablecoins and How Do They Work? | Gemini
