Using Professional Led Moving Head Stage Lights

By Betty Martin


Music venues, bars and clubs will frequently have stage or disco lights to enhance the atmosphere for concerts and live performances. Using standard equipment such as spotlights, can lights or beamed box lights will give a basic show and range of effects. A more professional and spectacular display can be achieved with professional led moving head stage lights.

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.

Stage lighting of this design has enormous flexibility; they can spin through a full 360 degrees and are able to rotate in many directions. Using a variety of LED bulbs in differing colors the operator can achieve any number of hues; adding a second unit can open up the whole spectrum. By linking the system to a DMX controller the number of functions is increased even further.

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.

This type of lighting can be controlled manually via a box as well and this is often very useful when lighting a performer who moves around on stage. Single beamed spotlight effects can be used to illuminate a solo performer and can be moved and kept on them as they move around the stage. Various colors and shapes can also be controlled by the person operating the control unit.

You need not be a trained lighting expert to get great results from a DMX controller. With a little practice and tuition on the system the results can be very dramatic. Text can be produced so the name of the band or club can be projected onto a backdrop or dance floor. Any number of shapes and colors can transform a bland room into a dazzling show. The more channels and LEDs that are available, the more complex and stunning the effects can be.

To install a full programmable, complex system, you will need to purchase cabling and connectors to ensure everything that needs to "talk to each other" can do so. The best person to do this work is a qualified electrical engineer who can also make sure the wiring is safe and not a hazard to the public, operator or performers. High quality connectors and cable can be expensive, but always buy the best you can afford.

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.
