Altman Lighting, aka Altman Stage Lighting Co., is a manufacturer of Stage, Studio, Architectural, and Video lighting products. Located in Yonkers, NY, Altman is probably the second most well-known name in stage lighting, following ETC. Before ETC's SourceFour was introduced in 1992, Altman's 360, and from 1974, 360Q, series of ERSs dominated venues from Community Theatres to Broadway stages for about three decades. Hundreds of thousands (if not millions) are currently hanging in the US. The 360Q series was discontinued in April 2015.
