Types of stage lighting and how it is used at concerts

If you enjoy attending concerts, you know how much excitement, joy and adrenaline you can feel when you hear your favorite songs and see the musicians on the stage. The musicians take care of the music itself, sound technicians make sure that you hear everything, but the visual component plays an important role on concerts as well. Lightning technicians are the ones who make sure that the light show on the stage goes along with the music, and some performers pay a lot of attention on the light effects during their performance. Sometimes they are even the integral part of the show, and you would not be able to imagine concerts of some performers without memorable visual effect in addition to the music.

Stage lighting can be divided into several categories, according to its function on the stage and the quality of light. The quality of light depends on several aspects, and different effects can be achieved on the stage by using the lights of different quality:

  • Color – color temperature of a lamp is measured in Kelvin and it depends on the material of the lamp. It is controlled by adding one or several filters (colored gels) into the optical path.
  • Intensity – it depends on a variety of factors, such as lamp power, the design and efficiency of the instrument, optical obstructions to the light and so on.
  • Direction – direction of the light determines whether it will be soft and dispersed or formed as a beam.
  • Position – naturally, the position of the stage lights determines the overall quality and effect the light show will create during the performance.

When it comes to the functions of a light show on the stage, it can be used in a variety of ways. Good visual technicians can create a variety of effects only by using stage lights, and they can create a whole new experience for the people attending the concert:

  • Selective visibility – the light used for selective visibility needs to show what is going on the whole stage.
  • The Revelation of form – the perception of three-dimensional stage elements can be altered by using proper lighting, which can create an interesting effect on the viewer.
  • Focus – beam stage light is used to draw the attention of the audience and focus it on one or several objects while distracting them from the rest.
  • Mood – mood on the stage can largely be influenced by light. Imagine the scene all colored in red, and one colored with a soft yellow or white light, and you will get the picture.
  • Location and time of day – when the lightning is the component of the concert, it can be used to display a specific location or time of day. In these cases, visual technicians also use mechanical filters to project different scenes.
  • Composition – the stage lighting can sometimes “paint a picture” and show the audience the specific areas of a stage in different colors and intensity of light.
  • Effect – a variety of special effects can also be used in pop and rock concerts and raves. Colorful lights and laser beams can also be used to create the atmosphere, and they are often combined with smoke and haze machines for additional effect.
