I tend to disagree. UVB is measureable. The amount of UVB that is sufficent can be measured by blood tests. What I am looking for is if anyone has done studies to determine how much or little is enough. It is already known that too much UVB is bad, as well as too little. For most people too much isn't a problem since their lights only produce a fraction of the UVB that would be put out by the sun. There are however, I am told lamps that will produce several times the amount of UVB the sun produces, making it more important to know proper levels.
