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.

These units can be bought in a number of sizes and vary in design considerably so selecting the most appropriate unit for your venue is of utmost importance. Some types can be used as a standalone floor rig, but most will need to be attached to either the ceiling or specialized metal racking. The effects themselves can be controlled manually, programmed to a specific routine or through sound activation when linked to the music system.

This kind of stage lighting is very flexible as the head units are built to spin 360 degrees and rotate in different directions. Varying colors can be emitted from the units depending on how many led bulbs are fitted and even more variations can be obtained by using two or more lighting units. When they are connected to a DMX controller many additional functions can be used.

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.

Like all things, your rig will require some routine maintenance. LEDs will fail after a time and require replacing. Lenses need cleaning of dust and grime to keep a sharp image. Within the unit itself the motors that swivel the heads will also need inspecting to ensure they continue to function properly.
