BTW, somebody on other forum argued that Lydon's result arnt valid neither because of blue contamination of the experiment.

It seem there is somebody obsessed with blue band spreading such things somewhere, and negating any other thing can have effect.

Of course, saying Lydon experiment was contaminated because some body is unable to accept his results is stupid, as it was very well designed, measured with spectroradiometer and lamp and filters used published. But who dont want to see, dont see
knna Reviewed by knna on . UVb an experiment Quick background: I have been using UVb supplemental lighting for many years now and have always thought it added to the finished product in a couple of ways. I had never promoted it's use on these boards because I felt it was dangerous and had real potential to harm people. That changed a few months back on the other UVb thread, and I came out of the closet in strong support of it's use. Well some here who's opinion I respect (like Weezard) held the opposite view and those discussions led me Rating: 5
