Well that was enormously condescending, especially when you take into account the bewildering ignorance of physics manifested. I'll break it down for you to make it a little easier to understand:

1) CFL and HPS lighting systems generate only heat and light.
2) For every watt of electrical power you give to such a system, it must therefore generate a total of 1W of heat power and light power combined.
3) But the proportion that is heat vs the proportion that is light may vary.
4) Therefore the CFL system must either produce more heat per watt than HPS, or more light per watt, or the same.
5) It is commonly said that HPS produces more light per watt than CFL.
6) It is commonly said that HPS produces more heat per watt than CFL.
7) This is impossible.

Talk of nebulous concepts like light quality is completely irrelevant to the above argument. The breakdown of light energy across the spectrum is also irrelevant to the above argument. Finally, the law of the conservation of energy IS a law of physics - in fact the first law of thermodynamics is essentially a conservation of energy law.
