The project on Retrofit Integrated Classroom Lighting System (R-ICLS) sought to develop 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 has developed and demonstrated four R-ICLS options that give schools a "good", "better", "best-pendant and "best-recessed" mehtods to combine state-of-the-art luminaires, lamps, ballasts, sensors, and controls into cost-effective, retrofit system solutions. Finelite and the CLTC are key project members.

The four system configurations have been installed and monitored in three different California school sites. A contractor installed 13 total classrooms with the R-ICLS systems, including monitoring equipment, before the 2008/2009 school year began. Data collection is complete, teacher surveys are complete, and analyses of the results is in progress. The final report is expected in fall 2009.

Images from the pre- and post-retrofit classrooms are shown below for the "Best-recessed" configuration. The video is courtesy of Finelite, Inc. 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). The system configurations report is provided in the current project information section. The data analyses report is pending final review by the research team.

One major outcome of this project is the development of the High Performance Recessed Fixture by Finelite. The product is featured in Finelite's brochure.
