Replacement Blacklight Bulb

The Flowtron BF130 is a 40 W ultraviolet bulb designed as a direct replacement part for compatible insect-control units. It fits models such as 3ZF09 and 2W547, restoring the high-intensity light that attracts flying pests to the trap. The transparent U-shaped bulb measures 14 1/4 inches in length.

Upgrading From a Spent Lamp

This bulb replaces an exhausted blacklight tube that no longer emits sufficient ultraviolet output to lure insects effectively. The jump is worth it when trap catch rates drop noticeably or the existing lamp shows visible darkening at the ends. It is not suited for fixtures requiring a different wattage, base type or physical dimensions.

Practical Limits of Ultraviolet Attraction

The 40 W high-intensity output defines the effective attraction radius for night-flying insects around the unit. Performance diminishes in areas with competing ambient light sources or during daylight hours when ultraviolet contrast is low. The bulb does not function as a general-purpose light source and cannot be dimmed or used in standard household sockets.

Questions about this item

What are the exact dimensions of the BF130 bulb to ensure it fits my unit?

The bulb measures 14 1/4 inches in length, 2 7/8 inches in width, and 1 11/32 inches in depth.

How do I correctly install this U-shaped blacklight bulb?

Align the U-shape pins with the socket slots and press firmly until seated; the step often missed is ensuring the pins are fully locked to maintain the electrical connection.

When should I replace this 40 W ultraviolet bulb for best pest control?

Replace the bulb annually or when the ultraviolet output visibly dims, as the high-intensity light degrades over time and loses effectiveness against flying insects.
