The group's principal activities are to develop, manufacture and integrate energy saving technologies and custom electric switchgear. The group operates in three segments: the energy technology segment designs, manufactures and markets energy saving technologies primarily to commercial and industrial customers. The energy saving product is the energysaver(tm) system, which reduces energy consumed by lighting, typically by 20% to 30%, with minimal lighting level reduction. This technology has applications in commercial buildings, factories and office structures, as well as street lighting and parking lot lighting. The power management segment designs, manufactures and markets a wide range of commercial and industrial switch gear and distribution panels for use in telecommunication and Internet network centers. The building control and automation segment provides integration of building and environmental control systems for commercial and industrial customers.
