I interpret the table a little bit different. In the row Heat I should add the percentage infrared because infrared is nothing more than a form of heat radiation when it hits something. Additionally the UV radiation is normally blocked in the lamp glass - it is converted into heat, in other words. Then the picture becomes an other.
And once again, if you use 100 watts in the wavelength range 420-460 nm, it is the same as if you add more than 400 watts of a full spectrum source with respect to the light that is active in photosynthesis. For most of the corals that live deeper than 3 meters in the wild, it is precisely this wavelength ranges that accounts for the photosynthetic growth of corals - virtually no other wavelengths, with the possible exception in the 470 nm area. The white light is needed basically just for the viewer. And that topic is not what I'm discussing right now, I just want to show that we are at a great risk when we concentrate almost all of the energy input in the wavelength regions that are biologically active.
