is this going to be a while?

The trouble is one question leads to another, and some conclusions lead to others. I can't figure out how to ask without the post getting too long. But here is the first of a number of questions.

Is there any relation between degrees Kelvin, and actual illumination (Lux)?

I ask this because I am confused. Light at noon over the tropical oceans is about 150,000 lux, and 5500K (John Tullock). As you go deeper into the ocean the shorter wavelenghts get filtered out eventually leaving blue, but the Kelvin goes up. The question is this blue light of lesser intensity or not (lux again). When we get this straightened ot I will tell you where this is leading. :?
