LONDON —For the seven-week X-Factor Live UK arena tour, which featured live performances by the top eight finalists from the 2013 series, the visuals included two video walls and 59 Clay Paky Sharpys. With all that luminous firepower, the production needed an even brighter followspot. LD Jonathan Rouse chose five Robert Juliat Lancelots, a 4000W HTI discharge unit, and a Robert Juliat Manon as a truss spot.
