I have acquired these searchlights from a lighting company who no longer needed them. I can not find any information about them. I am assuming that the manufacturer "USAsearchlights" is no longer in business. One searchlight seems to work. I am not sure how many hours the bulb has on it. The hour meter does not seem to work. I am not impressed with the brightness. It could just be the power source that was the problem though. The second searchlight has a broken bulb. It just arcs when I turn it on. Any information on these would be appreciated.
