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
