GlowBrick

Glow Bricks are Out of this world!.
Cast in Acrylic with a real bulb in side. These gather ambient light during the day and @ night will amaze you with their glowing.   No Plugs or power needed. Average amount of time the Glow Brick produces light is 8 hours and then it needs more light.  Just put in on your desk in a window by a light and you are ready again. 

The Glow brick is A Great Addition to the Bathroom or a kids bedroom as well for the free source light such as a night light!!!
The Glow Brick makes a great conversation piece as well.  We like to keep ours in the bathroom for those late night excursions so we don't trip over the cat/dog or misc toy that happens to have found its way on the floor.  This odd looking block of acrylic is one extremely strange piece of lighting.  It contains a phosphorescent real light bulb that seems to float within its transparent walls. When it gets dark, the bulb begins to glow a eerie shade of emerald green.  We promise it shouldn't scare your little ones if you use it for a night light though. For some of us a single light bulb in each room of the house is quite satisfactory for our lighting needs. But for gadget loving grown ups like the rest of us geeks that just isn't cool enough. Just a single bulb in each room, what a load of piff!  If you want to get a bit more experimental with your lighting illumination, now you can with the Glow Brick!By the day the Glow Brick is an eye catching artistic display of your unique style. It's really powered by the sun and ambient lighting and soaks up the light during the day and then releases it at night. As well as giving your room a very eerie glow, it's also a great centre piece for any gathering. Wait until your friends lay their eyes on it and we can guarantee that you and your Glow Brick will be talk of the town. The Glow Brick is the next best thing to remote-controlled lighting. In fact it's probably one step better because you don't even have to switch it on! No batteries required (solar powered)
