glowbrick

“The Glow Brick gathers solar power during the day and then, as night falls, gradually begins to light up. In a darkened room, it shines a comforting green light and gives the impression that its a bulb suspended in mid-air within the room.

And, since the Glow Brick doesn`t need to be turned on each night, it makes your otherwise empty house look like its inhabited during the evening. Style and security in one little acrylic brick.”
