Leviton Manufacturing, the Melville-based electric-products maker, said Monday it has acquired ConTech Lighting, a Chicago-based manufacturer of sustainable lighting products and fixtures.

The acquisition, Leviton’s second in the lighting industry since it purchased Anaheim, Calif.-based Intense Lighting LLC last year, allows the Long Island company to expand its product offerings. The two manufacturers will operate separate product distribution networks.

“We are excited to enhance Leviton’s lighting offerings and broaden our portfolio of solutions for customers together with ConTech Lighting,” Don Hendler, chief executive of Leviton, said in a statement.

ConTech Lighting currently employs 107 people and has its global headquarters in Northbrook, Illinois, just outside of Chicago, and a facility in Jiangsu, China.

The companies did not disclose the terms of the deal.
