It's more comparing spectrum and intensity of different light sources. The subtility eludes many.
You want to throw shading into it fine but mh's shade.
Each has it's plusses and minuses, strengths and weaknesses.
Mh's didn't start out tailored for corals
It took time
The first high intensity ( yep only reason they got where they are..mh's that is) light sources were hps.

I would not recommend it, the last tank I had seen with Sodium bulbs was 10+ years ago I guess... IMO I would not go back to the stone age

i do not believe that sanjay discussed or specifically mentioned pcs, vhos or nos.
however, he did discuss basic facts about light that would be generally usefully knowledge. one example is that it does not matter what the source of a photon is. it doesn't matter whether it comes from a flashlight, pc, led or mh, but what does matter is the amount of photons being made available over a given area over a certain period of time, that is par (photosynthetically available radiation). it is the amount of par that our corals are given which determines the amount of energy available fro our corals to absorb and thus affecting their health.
