This question already has an answer here:
I am making an illustration in Cycles Render of a table with a lamp and a Magic-8 ball below it.

(image above is the result of 1000 preview samples).
Here are a couple more view of the scene and its data:
The black ball's material
The lamp's material
Another light source is present.
What the lamp really looks like (y'know, IKEA).
I have tried full global illumination in the render settings, various sub surf modifiers to the lamp and to the ball, Multiple Importance on and off, but this didn't change a thing.
