I want to know the answer to the following question:
How much more efficient as standard incandescents was the white LED commercially available in 2003?
All the background I'm provided with is that "This produced a commercially packaged white light giving 65 lm/W at 20 mA, becoming the brightest white LED commercially available at the time, and more than four times as efficient as standard incandescents.". Is that enough to answer the question?
Answer: yes
