The SC-1201 is the perfect addition to any home haunt or professional haunted house. With 1200 watts of lighting capability, the SC-1201 can produce a very intense lightning show. Flip a switch inside the box and it becomes a dimmer unit. This feature is the reverse of a lightning controller. Lights that are normally ON, dim in reaction to the thunder tracks. Controller also works with our special delayed ThunderTracks included on the CD. (ThunderTracks CD included)
