ProSound offers a variety of stage lights, used for concerts and plays. ProSound is a company that offers a range of products for stage and other entertainment activities. A well-known version of stage light known as the spotlight is sold by ProSound in a variety of models as of 2015.
Stage lights are found in both low-key and expensive events, and cover the range of laser lighting and other special effects that use lights. Traditional stage lights are found suspended above a stage or at a vantage where they may cast light more effectively upon it. Some of them have remote controls, while others are programmable and yet more have the ability to change color and intensity. Some lights are designed to change focus, to cast light across an entire scene or shine a spotlight upon a specific spot.
Stage lights have been used for as long as stages have been in popularity, which is as early as the 1600s. Companies such as ProSound distribute equipment that functions similarly to equipment that has been used for centuries. These devices have been used extensively to provide cues or to adjust the mood of an event, or act to represent a certain time of day, as well as many other creative functions.
