Although gains in device efficiency have enabled LEDs to supplant fluorescent, incandescent, and metal halide lighting technologies, manufacturers continue to design luminaires around these traditional illumination sources. This article series will limit its discussion to the most prolific luminaire in commercial lighting applications (office, education, and healthcare): the semi-indirect linear luminaire, which was populated by linear fluorescent lamps in the previous paradigm.
