Looks like HPS is a "wasteful lighting technology", and Halophosphate phosphors are "crude" and "energy-hungry".

But the real question is: What will people do with "lower light"? They won't just install more fixtures, as that would be impractical and they won't really notice it.
They use the same power standards, so the power used will be the same. And don't forget that the eye can't notice small light changes well, if I remember correctly.
The article says that LED can use a tenth of the energy as older lamps, so if replacing a 100 Lm/W HPS lamp, that means 1,000 Lm/W efficiency!
