It’s not a flashlight that will fit easily in your pocket: The Lichternacht (Festival of Lights) in Solingen, in the German state of North Rhine-Westphalia, saw the unveiling of the world’s largest flashlight yesterday. Made by Zweibrüder Optoelectronics, it’s four meters long and features 19 high-powered LED lights. Thanks to the flashlight, the company has made it into the Guinness Book of Records. “This flashlight isn’t just a high performer, it came about thanks to high performance - 230 hours of work went into its production,” says Sven Objartel, managing director at Zweibrüder Optoelectronics.  

The lamp wasn’t just devised with its size in mind - it also makes a strong statement for energy efficiency. Today’s LED lights are up to 13 times more efficient than conventional light bulbs, and last 1000 times as long. LEDs (Light Emitting Diodes) are electronic light sources - based on semiconductors - that give off light when supplied with energy. If a luminous flux of 100,000 lumen is supplied to the flashlight, it consumes 1000 watts of energy. In comparison, 250 conventional 40-watt light bulbs consume 10,000 watts of energy.
