Leviton Manufacturing Co., Inc., Little Neck, N.Y., will expand its offering of high-end lighting control systems into stage and studio applications with the proposed acquisition of NSI/Colortran, Tualatin, Ore. Terms of the agreement were not announced.

A division of NSI Corp., Colortran provides lighting control and dimming products for applications such as auditoriums, schools, theaters, television stations and video production studios. Colortran would operate as a separate company, but would be part of the lighting controls division of Leviton, said Dave Harrison, vice president and general manager of the Leviton Lighting Control Division.

Although Leviton has been a player in high-end lighting control systems, this is the company's entree into the growing market for theatrical lighting controls in high schools, universities and theaters. Leviton executives see growth in the theatrical lighting dimming business in the next five years, especially with a commitment from the federal and state governments to fund these projects, said Harrison.
