You should use adaptive for all area_light. Start with adaptive 0, go to
adaptive 1 if you get artefacts (aray at least 5*5), adaptive 2 if you still get
artefacts (aray at least 9*9)...
With adaptive 0, area_light 1*x,1*y, 33,33 (or even 65,65) is almost as fast as
...4,4

With adaptive, the optimum aray size are: 5 (usualy to sparse), 9, 17 (I normaly
start at this density), 33, 65, 129 (this and greater are problbly overkill), ...
