An Aquascape bubble light is a vertical 20-watt mood light that is similar to a lava lamp. It contains a vertical water tank, a 12-volt halogen bulb and an air pump disguised in the bottom that pumps columns of bubbles into the tank, according to Amazon.com.
The halogen light shoots a beam of light into the tank through a color wheel that changes the light into four different colors, according to Amazon.com. The transparent vertical tank twists into a column and rests on a dome-shaped plastic stand. Aquascape bubble lights can be purchased at music and DJ stores, as well as online.
