HELP IN LIGHTING IN SKETCHUP vray

Good pm mga masters. Pahelp naman po regarding sa lighting in Vray Sketchup. 
I experimented using IES , rectangle and spot light found in Sketchup for Vray. I followed this certain tutorial : http://www.sketchupartists.org/tutorials/sketchup-and-v-ray/lighting-with-v-ray-for-sketchup-definitive-guide-part-1/ 

Nalagay and naset up ko na po yung both Emmissive and lighting based on the tutorial above pero di po lumalabas yung effect ng lighting.
 

Thank you in Advance.
