Lighting company Philips has developed an LED lamp that it describes as “the world’s most energy-efficient”.
It said the prototype tube lighting LED is twice as efficient as those currently used in offices and industry around the world but offers the same amount of light.
The prototype tube lighting produces 200 lumens per watt (200lm/W) compared with 100lm/W for equivalent strip lighting and 15lm/W for traditional light bulbs.
“This is a major breakthrough in LED lighting and will further drive the transformation of the lighting industry,” said Rene van Schooten, chief executive of light source and electronics at Philips.
Philips expects the light to go on the market in 2015, initially to replace office lighting.
