LED Lighting Fixtures Inc of Morrisville, NC, USA, which develops LED-based light fixtures for general illumination, says that its LRP-38 lamp has set a new standard for energy-efficient lighting by producing 659 lumens while consuming just 5.8W of wall-plug power (113.6 delivered lumens per watt), compared with 60W for an equally bright incandescent bulb, according to results of steady-state tests by the US National Institute of Standards and Technology (NIST) on LLF’s prototype PAR 38 self-ballasted lamp.

The lamp uses less than 9% and 30% of the energy consumed by incandescent and fluorescent sources, respectively. The lamp emitted a warm-white incandescent-like color of 2760K with a high color rendering index (CRI) of 91.2.

“The results of this prototype clearly demonstrate that LLF’s LED technology will surpass all existing forms of lighting in terms of performance,” says chief technology officer Gerry Negley. “The prototype lamp verifies that the LLF platform can be deployed in any form factor, which will allow full penetration of the global lighting market,” he adds. “We used Cree Inc XLamp and Osram Opto Semiconductors Golden Dragon products in the lamp, which we believe are the best LEDs available to maximize our proprietary system performance.”

The LRP-38 demonstration is the most energy-efficient, high-CRI white lighting solution ever developed, claims LLF’s Hong Kong managing director, Tony van de Ven. “While there is currently no timetable for a production release, this result shows that LLF’s technology with LED light sources has the ability to surpass 100 lumens per watt from a fixture, which is a revolutionary milestone."
