For this feat they are using completely special light.
Instead of the sun the green sulfur bacteria use the weak
jets of hot sources of the deep sea for their photosynthesis.
Hum... photo-synthesis, photo is greek for light, right? The bacterias
you described seems to use the heat energy to do whatever is done and
not light energy, therefore it couldn't be called photosynthesis, could
it? I'm not a biologist and i don't even know much about it, but that
just seemed wrong.
It seemed strange to me too, but if these hot water jets are as hot as
350C, they would be hot enough to emit some near-infrared and even a
bit of red light by black-body radiation, at the tail end of the curve.
Still, even if it emits a little red light the energy source would be
heat, as the generates little light. For what i know any eletromagnetic
wave that we can't see is just eletromagnetic wave, not light
