clinical Versus un-clinical?

I would like to know exactly the added value of the ASPH element in the 50 lux.

What is the clinicalness people are talking about? Can we see some examples of the clinical VS. Un-clinical? Is this quantifiable or simply subjective?

I mean, do the ASPH owners think it's clinical or is it simply the non-owners that think it's "too clinical"?? Is this simply a subjective issue?

Let's see some proofs.

And what is "clinical" anyways?
