A RGB Prolight LED mounted in a heat-sink, four rubber feet holds the glass ball (or rock) over the LED. Everything that can be illuminated from the bottom can be used. The LED has a effect of 3 watts and emits up to 30 lumen in 140 degrees. The LED uses 350mA, and a heat-sink must be used. The light is so intense that one should not look directly into ray of light.

The Prolight LED is controlled by AVR ATMega8. See Mood light (RGB) controller with 500mA outputs for more information.
