Replacement Ballast for 80W Units

This Flowtron ballast replaces the original component in compatible 80W fly killers and bug zappers. It supports the indoor commercial FC-7600, indoor stun unit FC-4700, and outdoor BK-80D models. The unit restores proper lamp ignition and regulation for continued insect control.

Thermal and Electrical Behaviour

The ballast manages the electrical load for an 80W ultraviolet lamp during continuous operation. Its metal housing dissipates heat generated by the internal windings without active cooling. Normal use produces a low audible hum typical of magnetic ballast designs.

Compact Metal Construction

Measuring 2.8 by 1 by 1.7 inches and weighing 10.88 ounces, the ballast fits within the existing fixture enclosures of the listed models. Wiring connects to the lamp holders and mains supply through the original terminals. The single-piece metal casing resists corrosion in humid outdoor environments.

Questions about this item

How do I install the Flowtron FLW5322790 ballast in my FC-4700 unit, and what is the common mistake?

Disconnect power, open the housing, disconnect the old ballast wires, mount the new 2.8"L x 1"W x 1.7"H unit, and reconnect matching leads. The frequent error is reversing the input and output wires, which prevents the 80W lamp from striking.

What maintenance or replacement will the Flowtron FLW5322790 ballast need over time?

The ballast itself is a sealed metal component with no user-serviceable parts. It requires no routine maintenance. Replacement is only necessary if the unit fails to start the 80W lamp or emits a loud humming noise during operation.

What is the first limit that appears when the Flowtron FLW5322790 ballast runs continuously in a BK-80D zapper?

The primary limit is thermal. The compact 10.88-ounce metal casing relies on the fixture's enclosure for heat dissipation. During sustained 80W operation, insufficient airflow around the 1.7-inch high body will cause the internal thermal protection to cycle the unit off.
