Information is sketchy, and perhaps uncertain, but Kentucky Lamp Company was owned by one Roy Burlew, who also founded the Ken-Rad (Kentucky Radio) Corp. in 1902. The two concerns might have been combined into one. They were located in Owensboro. I think GE bought Ken-Rad in 1945 and sold it in 1987. In 1929 the concern was called the Ken-Rad Tube and Lamp Corp. In 1938 they manufactured large tungsten filament lamps. Today the concern is called MPD.
