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 will be removed and the interior of each fixture cleaned. All wires will be replaced and rewired in accordance to UL standards and the lamp will be upgraded to modern LED lighting technology.
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.
Each downlight was received by Grand Light with significant staining to the current exterior finish due to the accumulation of bird excrement. The interior of each fixture had also accumulated a diverse collection of twigs, dirt, and feathers as a result of birds nesting.
All components were carefully removed from each fixture before Grand Light technicians begin to clean each downlight individually.
Inspection of each downlight revealed significant metal rot on nineteen of the sixty eight fixtures. All existing damaged and rotten sections will be replaced with formed steel panels that will be welded or braised into place before being ground weld smooth.
Grand Light technicians are currently removing the pre-refinish from the surface of each downlight through granite media blast to remove all stained finish and foreign material in preparation for a black matte polyester powder coat finish.
