I want to know the answer to the following question:
What are some of the luminous efficacies of yellow phosphor based white LED compared to blue?
All the background I'm provided with is that "For example, the luminous efficacy of a typical YAG yellow phosphor based white LED ranges from 3 to 5 times the luminous efficacy of the original blue LED because of the human eye's greater sensitivity to yellow than to blue (as modeled in the luminosity function).". Is that enough to answer the question?
Answer: yes
