Tall Lamp with White Bulb Looks Like a Face

I watched a horror film when I was little (I'm 29 now) and I can't for the life of me figure out the name of it.

This big house is on the coast somewhere and a little girl is fixated upon a tall lamp and the big white bulb looks like a face - she says its her dad (probably dead). It's actually a demon and in the end someone throws the light out the window where it crashes on the rocks near the water.

The last scene is of a cat walking up to the broken glass and then it's eyes change, meaning it's now possessed.

Please help me figure this out!!!

Thank you so much.
