The Eliminator E-144 Pirahna Mini Double Derby Special Effects Light is a smaller version of the popular E-108 Double Derby, yet it"s a powerful effect for both clubs and mobile DJs in its own right. The Eliminator Pirahna lighting effect features 2 x 120v 300w lamps (EL-64514) that respond sound actively via its internal microphone. The effect light creates a dramatic cluster of 32 multi-dichroic colored laser beams crisscrossing throughout the room.
