Nope. At least I don't think so.
The definition of candela there was an amount of light per unit of angle. Thus a 10,000 mcd over 7 deg would look as bright as a 10,000 mcd light over 14 deg, IF you're looking straight at it from the front.
Candela isn't the total amount of light put out- only the amount put out in one direction. Thus focusing comes into play.
On the other hand, the one which emits 10,000 mcd over 14 deg will definitely put out much more light power overall. I don't know how to do this with polar coordinates, but it's over twice as much, something like 4x I think.
So in answer to your question:
"I have seen a 11,600mcd green led with a view angle of 15 and a 7200mcd green led with a view angle of 30. Which one would look brighter?"
That depends on the testing conditions. In terms of total luminous power, I do not have the formula to compare them. The 11,600 LED will make a 1 ft spot 10+ ft in front of you appear around 50% brighter than the other, so it generally makes a better flashlight, hands down.
Someone correct me if I'm wrong...
