In quiz 1 of the PDD course, there is a question about efficacy of light sources.
Can someone please verify the statement below, I am finding conflicting information about this:
“The efficacy of an LED light is typically 35-90 LPW”.
Here is an example of a reference I found showing a much higher number: https://www1.eere.energy.gov/buildings/publications/pdfs/ssl/led_energy_efficiency.pdf
