    That would be completely determined by wattage. I'm not aware of any formula for that, but I've reached out to my nephew over at the U to see if he knows of anything.

    UVC is defined as 100nm to 280nm. Based on my interpretation of the above chart, that is too wide of a range to generalize.


    100nm light does not penetrate at all. Something like 99.999% of 100nm light is absorbed within 1CM of water.

    But 200NM light penetrates about as well as red light and the 280nm light penetrates almost as well as blue light.

    True story, cypho. It gets even more complicated when looking at the effect of the salts and turbidity yadda yadda yadda. To the OP, is this in regards to uv sterilization?
