Philips says it has created the "world’s most energy-efficient" LED lamp.
Philips researchers developed a tube lighting (TL) replacement TLED prototype that produces a record 200 lumens per watt of high-quality white light (compared with 100lm/W for fluorescent lighting and just 15lm/W for traditional light bulbs).
The prototype TLED lamp is twice as efficient as predecessor lamps, basically halving the energy used.
With lighting accounting for more than 19 per cent of the world’s total electricity consumption, Philips said the technology could drive massive energy and cost savings across the globe.
“This again is a major breakthrough in LED lighting and will further drive the transformation of the lighting industry,” said Rene van Schooten, CEO Light Sources & Electronics for Philips Lighting.
“It’s exciting to imagine the massive energy and cost savings it will bring to our planet and customers.”
The TLED lamp is expected to be marketed for office and industry applications in 2015 before being sold to homes.
Philips said it is the first time that lighting engineers have been able to reach 200lm/W efficiency without compromising on light quality, with all parameters required to meet the stringent requirements for office lighting.
The TLED lamps are intended to replace fluorescent tube lighting used in office and industry, which currently account for more than half of the world’s total lighting.
Conversion to the twice-as-efficient 200lm/W TLED lamps will generate significant energy and cost savings.
In the US alone, for example, fluorescent lights consume around 200 terawatts of electricity annually.
If these lights were all replaced with 200lm/W TLEDs, Philips said the US would use around 100 terawatts less energy (equivalent to 50 medium sized power plants) saving more than $12 billion (£7.8 billion) and preventing the release of around 60 million metric tons of carbon dioxide into the atmosphere.
