The "Nitebrite 300" flashlight has set a new Guinness World Record for being the world's brightest flashlight, with an impressive 501,031 lumens. Created by Chris Thiel, the product manager at Hacksmith Industries, this compact flashlight can illuminate an entire football stadium. This achievement marks the team's second entry into the Guinness World Records, following their creation of the world's first retractable proto-lightsaber.
