German firm beams its way to largest torchlight record

The world's largest torchlight has been unveiled by German electronics company Zweibrüder Optoelectronics GmbH & Co. KG

Measuring an incredible 400 cm (13 ft 1 in) long and 96 cm (3 ft 1 in) in diameter, the huge light was shown off in Solingen, Germany at an official Guinness World Records certificate presentation ceremony.

The torchlight is an outsized replica of one sold by the "Led Lenser" brand.

It consists of 19 LED´s which is comparable with 250 light bulbs and much for efficient than regular light bulbs. The torch comes to 1000 watts, about as much as a kettle needs.

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 Zweibrueder Optoelectronics.

The record-breaking project was conceived to shine a light on how energy efficient LED lights can now be.

Modern LED lights are now 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.
