This nifty Mathmos 9V battery light from ThinkGeek “is made from Acrylic and the light is created by 2 LEDs — light appears white when switched off and glows red when turned on.” Click here for one more picture.
An ideal alternative to the tea light the 9 Volts looks great when used in groups to provide an ambient lighting effect. Ideal for use in the home or when entertaining outdoors.
