Functional Devices introduced a series of half-light controllers that provide independent control for multiple ballast light fixtures from a single existing wall switch. The new two-stage and three-stage half-light controllers can reduce a building’s light output, says Functional, enabling lighting users to enjoy the benefits of lighting control with just a simple toggle of their wall-based light switch. The half-light controllers from are compatible with the market’s range of fluorescent and HID lamps, and represent a simple alternative to costlier and more complicated dimming systems and components.
