The invention consists mainly of two major sub-systems, ie, three colored lamps and a solid state digital computer. The three lamp colors are green, blue and red. The Computer consists of several TTL devices, diodes, capacitors and resistors. The computer electronics generate the trigger pulses for controlling the firing of triacs which are power devices controlling the amount of power delivered to the lamps. Each lamp is driven by one triac. However, each triac has the power capability to drive several lamps. These lamps generally are immersed in water but could also be used out of water.
