In my test scene, the primary light points directly at the urn (used Point At) and casts the shadow on the wall.

The relevant dials for it are as follows:

xScale 349%

yScale 582%

scale 211%

intensity 250%

xtran 0.000

ytran 8.000

ztran 21.000

The other 2 area lights in my scene are very low intensity and were just for side key lighting.
