Too much light??

Yes there is such a thing as "too much light." It is species dependent however. Photoinhibition is possible and varies dependent on the species of coral/zooxanthellae being investigated - essentially blasting corals with tons of light can be a waste of hydro. But excessive lighting can also produce some unique effects so "too much light" is a relative term depending upon your goals (growth, fluorescence, etc.)

ahh yes, a waist of money yes, but not to much light which will fry the coral, it will just stop using it.

so basicly you have said there is to much light but you are not in the context of this topic, we are not talking about "how much can I get away with and I don't want to use any extra hydro whatso ever"

but rather will to much light kill my corals, I re read the article you listed and a few others and not one of them is saying that the lights we are using in this hobby will kill our corals if they are properly adjusted to the light.
