Using Professional Led Moving Head Stage Lights

By Betty Martin


Many bars, nightclubs and music venues have disco or stage lights fitted to illuminate the performances and concerts. Basic effects can be achieved with standard units such as can lights, spots or multiple beamed box units. A better way to put on a spectacular light show is to have professional led moving head stage lights installed.

Moving head units can be purchased in many different sizes and designs and it is important to select the correct type to suit your needs. They will usually be ceiling mounted or attached to metal racks and in some cases are used as standalone units on floors. The units work in a couple of different ways either through sound activation or by having someone to manually control or program them to perform sequenced routines.

Moving heads are extremely versatile due to the way they are designed to rotate and spin in any direction. Many colors can be obtained from a single unit by fitting different led bulbs but better effects are obtained by using multiple light units. Extra features may be utilized when connecting them to a DMX control box and programming different sequences.

If the lights are to be operated using just sound activation they will turn and swivel in conjunction with the music or beat. Direction will be random and not controlled and may also alter depending on the volume levels within the room. When they are connected to a control unit they can simply be programmed to operate to a sequence chosen by the programmer.

When a soloist is lead singer is the focus of the lighting, manual operation through a DMX box allows the operator to better track their movements across the stage while they perform. The unit can also function in the same manner as a single spot to highlight a particular performer or area of interest to the audience. Both the shape and color of the beam can be controlled by the operator to match the light show to the action on stage.

When these lighting units are connected to a DMX box infinite movements and colored patterns can be programmed after a little tuition on how to operate the system. Club or bar logos can be projected onto walls and floors and even small sections of text. The complexity of the effect will depend on the amount of led lights in the units and on how many channels the DMX box has on it.

When installing a more complex system which is fully programmable you will also need the correct type of cable and plugs to connect everything. Any professional lighting system should always be fitted by a trained electrical engineer and checked for safety. Some of the cabling and connectors can be costly but it is advisable to always buy the best quality that is available.

Professional stage lighting will need routine checkups and inspections if it is being used regularly. Glass lenses should be kept clean and free from debris and led bulbs should be replaced in the event of failure. The small motors that control the movements of the unit should also be maintained and inspected from time to time.
