You are on the right track with area lights, just fiddle with the parameters
more.  Increase the number of lights in the grid and increase adaptive,
render time will go down though.  Also, for globe lights use 'circular' and
'orient'.  Jitter may help smooth results at lower grid and adaptive values.
