I am helping with a haunted trail and we want create a lightning/thunder storm scene. I have access to a large DJ system and also I have a lots of lights Par cans and various floodlights. I am looking for a controller to accomplish lighting that reacts like lightning with sound played through the DJ system. I am aware of I-zombie products and audio-to-light modulator hobby kits. Anybody have any feedback on the i-zombie controllers or any other possible commercial solutions, like an american DJ product or something? Also it must handle at least 800 watts, because the area is going to be around 100x100.

Thanks in advance,
