Flowtron BF-190 40 Watt U-Shape UV Replacement Bulb for BK-40D.
Family-owned since its start in 1920, Armatron International began operations as an automobile radio manufacturer. After over 80 years of innovation, it is known today through its Flowtron division as a worldwide leader in outdoor products. From the 1920s through the 1960s, the company advanced its manufacturing and design capabilities to include tape players and stereo systems for automobiles and for home use. Responding to increasingly fierce competition from the Far East, the company began diversifying into other product lines. In 1974, the Flowtron Outdoor Products Division was formed to design, develop and manufacture electric heaters and electronic insect killing devices for residential and commercial use. In 1980, the company changed its corporate name from Automatic Radio Manufacturing Company to Armatron International, Inc. to better reflect its expanded line of consumer products. Today, through its Flowtron Outdoor Products Division, the company designs, develops, manufactures and sells a select line of lawn and garden products. Its products are distributed to major retailers in the USA and Canada and to foreign markets throughout the world. All products are proudly manufactured in the USA in facilities in Malden, MA, and Ft. Wayne, IN.
