Animated Lamp - End Results

[Moaddibb]

Hi,
I finally finished with the project and it looks nice, but still, I have few questions:

1. When I shifted from “regular” IK to vertex groups, the behavior changed a bit. Now when I drag the base, it moved the whole lamp, instead of keeping the “head” (shader bone) in its place. Is there a workaround?
2. After rendering, I see those dot. when I increase the sampling (i.e. to 3000) they almost disappear. Is there a better way to get rid of these dots?

256 samples:

3000 samples:

Thanks

These dots are called ‘Fireflies’, search for it on the internet.
