A number of different technologies make lighting
possible, including various light sources, lighting fixtures (known as
luminaires), and lighting controls. Light sources include the
traditional incandescent and fluorescent lamps, high-intensity-discharge
lamps, and now solid-state devices that promise to change the way we
light our world. Ballasts regulate the power to some of these light
sources. Controlling the lighting systems are switches, dimmers,
occupancy sensors, photosensors, and even automatic systems that can
reduce electric load demand when needed.
The LRC tests, evaluates, and develops
all types of lighting technologies in order to promote lighting that is
energy efficient, reliable, and easy to use.
