US introduces $60 LED light bulb

A prize-winning light bulb that lasts for 20 years is going on sale in the US on Sunday - also known as Earth Day.

Made by Dutch electronics giant Philips, the bulb swaps filaments for light-emitting diodes to provide illumination.

Using LEDs endows the light with a long life and a hefty price tag. The first versions are set to cost $60 (£37).

Philips has arranged discounts with shops that will sell the bulb meaning some could buy it for only $20 (£12).

The bulb triumphed in the Bright Tomorrow competition run by the US Department of Energy that aimed to find a energy efficient alternative to the 60-watt incandescent light bulb.

The DoE challenged firms to develop a design that gave out a warm light similar to that from an incandescent bulbs but was much more energy efficient.

Philips was the only entrant for the competition and its design underwent 18 months of testing before being declared a winner.

A cheaper and less efficient version of the LED bulb is already sold by Philips in the US and Europe.

LED bulbs face competition from compact fluorescent lights which are almost as energy efficient and cost a lot less.

Sales of more energy efficient bulbs are being aided by official moves to end production of higher wattage incandescent bulbs.

Production of 100 watt bulbs has ceased in the US and Europe. Production of of 60 watt bulbs has been stopped in Europe and is being phased out in the US. From 2014, incandescent bulbs of 40 watts or above will be banned in the US.

  • Bristol Academy extends reach overseas with first foreign students

    With the doors to its brand new £1million training centre officially open, one of the UK's leading apprentice training providers, Bristol based S&B Automotive Academy, is showcasing its world-class facilities by launching a series of foreign student exchanges for the first time in its 41-year history. To get a flavour of what life is like as an apprentice in the UK, the Academy hosted 16 apprentice engineers and bus drivers from the G9 Automotive College in Hamburg, Germany, as part of a Europe-wide vocational training initiative called the ‘Leonardo Programme’ with support from the European Social Fund. In a reciprocal arrangement, S&B will be sending nine apprentices to Germany during February 2012 so that they can get an appreciation of life in the automotive industry on the Continent. A further three German exchange groups are being planned for next year. Designed to assist the development of vocational skills and training across Europe, including work placements for trainees, the Leonardo Programme has a budget of €1.75bn, which is helping to encourage UK organisations to work with their counterparts abroad. In what is expected to be another challenging year for employers in the UK automotive sector, S&B’s Chief Executive, Jon Winter, claims that the exchange initiative will bring many benefits to the Academy and its apprentices: “In a world of global automotive brands, it’s important for our learners to understand the international context of the industry they have chosen to make their career. This new exchange programme will enable apprentices and Academy staff alike to achieve a better understanding of the challenges and opportunities within the automotive arena in Europe. With the Academy’s influence also extending to the USA and Asia, there’s every possibility that this initiative could move further afield in the future.” Continued Winter: “The need for skilled technicians across the world is on the increase and we actively encourage our apprentices to look at broader horizons during their training. Many of them have already learned the phrase ‘Vorsprung durch Gelehrtheit’, quite simply, ‘Advancement through learning.” In the 2010/11 academic year, S&B doubled the number of successful Apprenticeships over the previous year with some 350 apprentices graduating from the Academy. At the same time, achievement levels reached an all-time high with an overall success rate of 85%. For those learners on the Advanced Apprenticeship three-year programme, success rates were even higher, at over 98%.
