The project on Retrofit Integrated Classroom Lighting System (R-ICLS) developed retrofit lighting solutions for classrooms to ensure that the luminaires, sensors, and controls work together to provide proper lighting for general and A/V requirements together with lighting for the white board. The project team developed and demonstrated four R-ICLS options that give schools a "good", "better", "best-pendant" and "best-recessed" methods to combine state-of-the-art luminaires, lamps, ballasts, sensors, and controls into cost-effective, retrofit system solutions.
Project team: Finelite and the CLTC
Four levels of R-ICLS systems were developed and demonstrated in 13 classrooms in three schools in California . Results have shown a range of equipment and installation costs and energy use impacts with positive teacher feedback. Finelite has commercialized the R-ICLS systems.
An image from the post-retrofit classroom is shown below for the "Best-recessed" configuration. The existing lighting layout consisted of three rows of 4-lamp, 4-foot, T12 fluorescent troffer style fixtures (4 units per row) and were replaced with three rows of 2-lamp, 4-foot, T5 fluorescent troffer style fixtures (4 units per row).
