Osram Sylvania, the Danvers, Mass.-based lighting subsidiary of Siemens, announced it has signed an agreement with Townsend Ventures, LLC, to increase its stake in Encelium Technologies from 15 percent to 100 percent. Financial terms of the deal were not disclosed.

In announcing the move, Osram said taking full ownership of Encelium will improve its position in two key global growth markets, LED-based technologies and lighting controls and Light Management Systems (LMS).

Encelium, headquartered in Teaneck, N.J., is essentially a software technology development company concentrating on advanced, addressable lighting control and energy management systems for commercial and industrial buildings. Since its founding in 2001, Encelium has grown to employ approximately 70 people in the United States and Canada. Taken under the Osram Sylvania umbrella, Encelium will become part of Osram's General Lighting - LMS business unit, which includes the rest of the company's lighting management products. The Encelium brand will continue to be developed, an Osram spokesperson said, alongside the company's existing lighting controls, which are primarily marketing under its Optotronic brand.
