Based in Doncaster, Cooper Lighting and Security Ltd was formed in 2000 by the merger of three companies - Crompton Lighting, Menvier and JSB – which had been acquired by Cooper Industries in the late 1990s. The Crompton Lighting brand is well known in the commercial lighting sector, while Menvier and JSB are market leaders in emergency lighting as well as having a strong position in the market for fire-detection equipment. A fourth brand, Axent, was launched in 2007 to focus on the market for architectural and display lighting.
