I believe that effect is related to the frequency of the strobe.  If it's too  
close to your brain's alpha frequency, the brain will try to synchronize the  
alpha frequency to the strobe, which results in the kind of sensations you  
described.  In people with epilepsy, that can induce a seizure.  I doubt you'd  
have problems with an intermittent strobe (flashes for a few seconds during a  
ring, than not lit (I wanted to say "silent") in between rings) because the  
synchronization effect requires a few seconds of a steady frequency.
