Rectangular Light plays a very important role in V-Ray. Despite its easy of use, it also gets a 
smoother final
result
. 
Unlike
the
Point
Light
, 
Rectangular
Light
doesn
'
t have the worry about the 
angle of the light. It also allows reflective material to bounce the light around the scene. Other 
type of lights will not be seen in a
reflective
object
. 
Below are some important characters about 
Rectangular Light.
Size does matter
See images below and you will find the size of the Rectangular Light has an affect its intensity.
The Characteristics of Rectangular Light
Shadow changes according to the size.
Larger Rectangular Light spreads out to a larger area, so the shadow is not as clear as you will get 
from a smaller Rectangular
Light
. 
Compare images below and you will see the differences between two different light sizes. The 
one on the left is rendered with smaller light.
If you want to have a stronger
shadow
, 
we
do
not
recommend
you
set
the
intensity
way
high
and
make
the
light
size
really
small
. 
It
