On November 29, 2007, at the White LEDs-07 International Conference in Japan, LLF (LED Lighting Fixtures) announced that its LED lighting performance has broken the current record. The prototype of PAR38 self-ballasted lamp developed by LLF (tested by NIST under steady state) has a luminous flux of 659 lm at 5.8 W, a luminous efficiency of 113.6 lm/W, a relative color temperature of 2760 K, and a color rendering index of 91.2. .
The LLF lamp uses Cree's blue-shifted yellow Xlamp LED and OSRAM's red-light Golden Dragon LED, which consumes less than 9% and 30% less energy than incandescent and fluorescent lamps, respectively. The prototype of the LLF scale lamp clearly demonstrates that its LED technology will outperform all existing forms of illumination in performance.
