That is universally true for outdoors, and only partially for indoors (since the last method can provide sun-like light power for just a small zone -- about 2-3 feet -- under the lamp).
Good luck!
I respectfully disagree with this statement. Geometry limitations are different indoors vs out, but indoors has the advantages of both total control and custom training. There are plenty of people getting creative with the shapes of things indoors, so I think the opposite as you; that soon there will be some steps forward in indoor lighting efficiency.
