 In order to achieve this effect it is necessary to create an intense field of UV light throughout the entire playing space.Because the intensity of light emitted from a typical 'black light' source diminishes significantly with increased distance from the source, covering an entire theatre space with UV light requires either that the 'black light' sources be spaced as close as one meter apart or emit much more light than a typical 'black light'.Another important consideration is that, since most of the space is completely dark, and the form is heavily dance based, a single wrong move by a single performer can negatively impact the entire production.
