Purpose and fit

The Flowtron FLW5329988 is a 25W 120V Class B ballast assembly designed for Flowtron bug zappers. It serves as a direct replacement for the Indoor Sconce Fly Killer 40W (FC-4400) and the 80W model (FC-4800). Facility managers and homeowners maintaining these specific units will find it the correct spare part.

Build and connections

The ballast measures 2.5 by 2.5 by 1.6 inches and weighs .68 pounds, fitting the existing housing without modification. It operates on standard 120V indoor supply and uses the original push-button and touch control scheme. The compact footprint allows straightforward installation inside the sconce enclosure.

Upgrade context

This part restores ultraviolet output when the original ballast fails, returning the trap to its rated 25W consumption. It is not a performance upgrade; it simply replaces a worn component. Buyers needing a different wattage, voltage, or compatibility with other fly-killer models should look elsewhere.
