Does anyone have one of these:

I love anything that "lights up" and these 8'' spheres look really cool on YouTube, so I

ordered one :)

 

It also looks like there are 2 different manufacturers of these, but I may just be confused! :\

 

I wonder if you ever have to change the bulb, or if it even is changable!?

 

They say it does not have a switch, so you need to unplug it to turn it off!?
