Light bulbs that are said to last for more than two decades while consuming very little energy may go on sale later this year.
US firm General Electric, Dutch company Philips and UK-based Sylvania all showcased their products at the Light Fair industry conference in Las Vegas.
Using light-emitting diodes (LEDs) instead of filaments, the bulbs are meant to produce as much light as a 100-watt incandescent alternative.
However, LEDs are not usually cheap.
In April, Philips introduced its LPrize LED that will cost $60 (£37) - but consumes only 9.7 watts while giving off the same amount of light as a 60-watt incandescent lamp.
The company has arranged discounts with shops that will sell the bulb for as little as $20 (£12).
The new EnduraLED from Philips looks similar, but is said to be even more efficient, equivalent to a 100-watt incandescent bulb while consuming nearly four times less energy.
Both Philips and Sylvania said their products are due to appear in stores later this year, while GE plans to sell its bulb early next year. The firm currently sells a 9-watt LED bulb that is made to replace a 40-watt incandescent, for about $50 (£31).
All three bulbs are meant to last more than 20 years, if used about three hours per day. |
