Using adaptive 0 may be suficient. Try an area_light aray of 17*17 or 33*33 or even
65*65. Adding 
jitter 1 may help but get less improvement when using denser arays.
I agree on more samples in the media, avoid using more intervals when using method 3
(the default) 
as it dramaticaly increase the render time. 100 samples is faster than 10 intervals!
