Cree, the US-headquartered LED maker, has once again set a new benchmark for the efficacy of white-light production.
It has achieved a laboratory demonstration of 231 lumens per watt - which is approximately a ten per cent improvement on the previous record.
Achieved in standard conditions with a single-die component at room temperature and an operating current of 350 mA, the result beats the company's previous best of 208 lm/W.
John Edmond, director of advanced optoelectronics, commented: "It wasn't long ago when 200 lumens per watt was considered the theoretical maximum efficiency [sic] for a lighting-class LED. We broke that barrier in 2010."
"The innovation from our labs is the foundation for our industry-leading XLamp LED family, and an invention that continues our leadership of the LED lighting revolution," he added.
Meanwhile, it has been revealed that EiKO Ltd's next generation of LEDs offer a host of new features.
These features include top quality Cree chip construction, UL and CUL approval and Energy Star-rated performance, as well as greater flexibility when adjusting ambient light levels.
