I know the correct answer is based on one of the NCARB study resources, but it seems like that information is outdated. There are now high-performance LED fixtures on the market with efficacies of around 200 lm/W, which are higher than high-pressure sodium.
If a question like this came up on the actual exam, would NCARB expect us to answer based on the study materials, even if they don’t reflect the latest technology?
