The online platform for V-Ray users to submit, vote, and collaborate on creative suggestions.
There's currently only a very limited set of ways to control vray lights. Other renderers have a wide range of ways to shape and affect light sources. Ranging from simple barndoor controls, over spotlight control and softness to focus tinting and very fine grained attenuation control (inverse square, half distance, ramp, ranges,..). For reference:

This is extremely useful and I love doing shot lighting with these.
