Here's a neat one - Entertainment Earth (sponsor) has a Star Wars Yoda Lightsaber Table Lamp from United Cutlery, and it's pretty neat. You can outfit it with pretty much any light bulb, including a green one which you can snag at pretty much any Walmart or party supply store for a couple of bucks. This definitely adds a nice glow to the item. See the glowing green animated pic after the jump.
It's basically a Yoda lightsaber hilt mounted on a black base, with a lamp stuck in it. For the asking price ($68.99) the quality is quite good, but the lightsaber part isn't removable. It basically feels like a prop replica, minus the fact that it's got a lamp stuffed in there. As licensed housewares go, it's pretty awesome.
