Flowtron Replacement UV Bulb Pack for BK-40CCN — 2-Pack BF-190 Compatible Tubes, Easy Install

Flowtron Replacement UV Bulb (2-Pack) for BK-40CCN restores your BK-40 outdoor bug zapper's attracting power with two ready-to-install ultraviolet tubes.

When the original lamp in your Flowtron BK-40 unit dims or burns out, insect catch performance drops quickly — replacing the lamp is the simplest way to bring the device back to peak effectiveness. These two BF-190-compatible UV bulbs are designed to match the BK-40's specifications so you can swap them in without fuss and get reliable insect attraction through the evening and into the night.

How do these replacement bulbs keep my BK-40 working well?

Ultraviolet lamps are the primary visual lure for flying pests; over time light output falls even if the bulb still lights. Putting in fresh BF-190-compatible tubes restores the lamp intensity and helps your BK-40 draw insects the way it did when new.

• Two-tube pack for immediate replacement of both worn lamps
• Same size and connectors as the BK-40 original units for easy fit
• Replaces faded bulbs to recover attraction performance

Are these bulbs easy to replace and install?

Yes — the tubes are manufactured to the BK-40’s socket and mounting style so typical users can swap them without tools beyond basic care. Always disconnect power before handling the lamp, then slide the old tube out and seat the replacement firmly into the sockets.

• Plug-and-play compatibility with Flowtron BK-40 models
• Standard tube ends that align with BK-40 lamp holders
• Instructions: power off, remove old bulbs, install new bulbs, restore power

What does the two-pack offer versus buying one bulb at a time?

Purchasing a pair saves cost and time: if one tube has reached end-of-life, its partner is likely near the same stage too. The two-pack ensures both lamps are matched for brightness and color temperature, which helps the unit operate evenly and reduces the chance of replacing the second bulb shortly after.

• Cost-effective compared with two separate purchases
• Both tubes match in light output for balanced operation
• Reduces downtime by providing an immediate spare

Will these bulbs work in other Flowtron models or brands?

These are specifically BF-190-compatible tubes designed for the BK-40 outdoor bug zapper; they may fit other devices that accept the same tube type and socket, but confirm model compatibility before installing. Always check the recommended lamp part number in your unit’s manual to avoid incorrect fits.

• Designed for Flowtron BK-40 models (BF-190 compatible)
• May fit other devices using the same tube specification — verify first
• Using the correct tube avoids installation issues and preserves performance

Who is this for? This 2-pack is aimed at Flowtron BK-40 owners who want a quick, economical way to restore their unit’s insect-attracting light. It suits homeowners, property managers, and anyone who relies on a BK-40 for outdoor insect control and prefers to keep a matched spare on hand for uninterrupted use during warm months.
