The Flowtron Replacement Lamp Ballast is a crucial component for maintaining the efficient performance of your Flowtron Bug Zapper or Fly Killer system. It works in tandem with the UV bulb to ensure it operates at full capacity. The UV bulb acts as the main attraction for insects, drawing them towards the device. When insects come close, they are either immediately zapped and killed by the high-efficiency shock grid, which remains non-clogging for consistent performance, or they are trapped on the hidden adhesive fly boards, depending on the model. This dual-action process ensures maximum insect control. The UV bulb is essential for keeping the Flowtron Bug Zapper and Fly Killer series working continuously, providing round-the-clock protection for your home and outdoor spaces. By replacing the lamp ballast, you help maintain the system's efficiency, ensuring the UV bulb remains functional and your insect control system operates smoothly. This replacement part guarantees you and your family stay safe from unwanted pests year-round.
