DMX (Digital Multiplex) controlled lighting is a type of lighting system used in live theater and concert events. This system allows various lights and effects simulators to be connected to one controller. This controller directs all of the lighting effects. DMX lights are specially made for nightclubs, theaters and concert venues. These lights have special cables that transfer large amounts of data back and forth to enable various functions. All DMX controllers and DMX lights exchange information using the DMX 512 protocol. DMX 512 is the universal standard protocol used in the lighting industry.
Many DMX lighting options are available: spotlights, movable can lights, LED lights, laser lights, strobe lights and dimmers. A few different types of DMX strobe lights are available. Xenon lamp strobes produce intense white light for short durations. LED strobes use less electricity than Xenon strobes; however, the effect is not as intense. DMX lighting is also used in other applications such as for theme park attractions and building exteriors. DMX systems are also used to control fog machines, haze machines and snow machines.
Either a lighting control console or a PC-based console runs a DMX controller. A PC-based console is more functional and allows a technical to program a full show in advance. The PC-based console operates under a specific software program. This software provides the ability to program the lighting and effects so that they perform their different functions at specific times or in a sequence.
Most music stores offer DMX fixtures and effects. Specialty theater supply companies may also offer DMX lights, effects and controllers. However, the equipment from these companies is typically high end and thus more expensive. The Internet is another resource for purchasing DMX lights. Renting DMX lights and equipment from a theater rental company is another option.
