ABSTRACT:
An insect electrocution apparatus and method of operation utilizing a series connected, dual coil primary of a ballast/step-up transformer to provide increased impedance only during the starting of the insect attracting fluorescent tube. The fluorescent tube is connected between the two primary coils with the fluorescent tube starter and one of the primary coils connected in series with the fluorescent tube filaments. Upon starting, both coils are energized and provide the desired amount of impedance. Once the fluorescent tube ignites, the starter and the second primary coil are operationally removed from the circuit leaving only the first primary coil to provide ballast for the fluorescent tube.
