Hey
@Roger A. Shrubber and
@ttystikk and everyone else.
This 1000w light of any kind will produce 1000w of heat thing has been bothering me for some time, since its one of those things often repeated on here. I'm wondering if its been repeated so much we tend to believe it without question?
So my thoughts until been told this "science fact" were light converted to photosynthesis (no matter how small that is) is been used as that and not turned to heat.
I hear the argument "if you put 100w Y bulb and 100w X bulb in a closed box the same heat will be created because energy cant be destroyed or created and 100w is 100w"
So I just had a google about, which I have tried before, but today I find something interesting, which to me disproves the argument above!
I respect all your opinions so please check out this link and look at the two experiments and tell me if I'm wrong and why I'm wrong if I am.
