The FX-4 is a handy device that contains four light effects in one system. This small device may be affordable, but it packs a powerful punch. The system contains a LED wheel that projects patterns on the dancefloor, a disco ball, a red and green laser that projects laser beams across the room, and a strobe light. Furthermore, the FX-4 is easy to use as it has an Automatic Mode and a Music Mode. This means the system responds automatically to its environment or the music so you won’t have to worry about programming or changing things by hand. However, it is possible to program the system for those who want to do that.
