Kentucky Greenhouse Home To World's Largest LED Installation

An AppsHarvest greenhouse under construction in Morehead, Kentucky, is said to be the world's ninth-largest building at more than 2.7 million square feet. It will be outfitted with a $15 million hybrid LED lighting system, making it the world's largest LED installation for a single building. AppHarvest rep won't say exactly how many LED fixtures it takes to make the largest LED (light-emitting diode) installation, but they note that a review of media reports and other publicly available information shows the eight other largest buildings either don't have LEDs or haven't had them all installed at one point.
