Grand Light has begun restoring sixty-seven historic exterior downlights from Massachusetts Institute of Technology – Kresge Auditorium. The first phase of restoration began with each downlight being inspected and reviewed to measure the severity of finish deterioration and mechanical failure. The exterior finish had been severely stained by bird excrement while the interior of each fixture had accumulated a significant amount of debris from birds nesting. It was determined that the most appropriate method of restoration would be to re-finish each fixture. The current dilapidated finish would first be remove by media blasted with a granite to remove all of the existing finish in preparation for a black matte polyester powder coat finish. All foreign material would also have to be removed and the interior of each fixture cleaned. All wires will be replaced and rewired in accordance to UL standards.
In addition to finish deterioration, a damage inspection and subsequent report for each downlight revealed significant metal rot on a large number of the fixtures. Of the sixty-seven fixtures, nineteen had existing damaged and rotten sections which will require additional metal work to repair and/or replace the corroded metal to match existing components.
