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.

Manual operation can also be achieved by using a DMX box and this is particularly beneficial when focusing on an artiste who moves around whilst performing. Single spotlight type effects may be aimed at different areas of the stage. Different kinds of shapes and colors can also be input and then will be emitted from the units.

For better effects these moving head units can be connected to a DMX box enabling different combinations of movements and patterns to be programmed. Pictures and shaped objects can also be projected on to various areas of the room and this creates some interesting effects. The amount of led lights in the unit and channels used to program the light will determine the complexity of the effects that may be obtained.

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.
