Almost there [:)] Numeric model identifiers are wrong - your lightsource properties are #2 while the other model properties are #1.

Should be:
lightSourceX#1=5.4
lightSourceY#1=5.4
lightSourceZ#1=7.0
lightSourceColor#1=#ffffff
lightSourceDiameter#1=5.0

ok

PS: #ffffff is very very white.... - to make it realistic you might want to add a touch of yellowish
