"The original fixtures were purchased from an industrial lighting supplier in San Leandro, CA about 10 years ago. Since I had no trouble installing the original seven fixtures, it was easy to replace the one which had been destroyed by careless pressure washing prior to an exterior paint job. I live right on the coast and salt mist tends to destroy anything except plastic, so the original purchase was to replace case aluminum floodlights which were "long gone". I wish that all the suppliers with whom I've dealt provided the level of satisfaction that you have. Thank you." RK - CA
