Flowtron BF-35 Replacement UV Bulb 3-Pack - Reliable Bug Zapper Bulbs

In this review the Flowtron BF-35 Replacement UV Bulb 3-Pack is evaluated for anyone who owns a Flowtron BK-15 outdoor bug zapper and needs a ready replacement. The bottom line: this three-pack is the practical choice for homeowners who want a quick, cost-effective way to restore their unit's insect-attracting power, since the UV bulb is the primary element that draws mosquitoes and other pests toward the shock grid.

Key Features

• Pack size: The 3-pack offers a lower cost per bulb and keeps spare bulbs on hand so a failed lamp does not leave a zapper useless for long.
• Compatibility: Designed to work with the Flowtron BK-15 Outdoor Bug Zapper so fitting and operation are straightforward without guessing about size or output.
• Primary attractor: The bulb provides the ultraviolet light that lures insects to the non-clogging, high-efficiency shock grid, restoring the zapper's effectiveness.
• Simple replacement: Customers report the bulb is an easy fit, making bulb swaps quick and fuss-free for routine maintenance.
• Bright UV output: The lamp produces a clear, bright UV light that customers say improves insect catch rate compared with dim or aging bulbs.

Who It's For

This 3-pack is best for homeowners, renters with outdoor living spaces, and anyone who already owns the Flowtron BK-15 and wants to keep it operating at peak performance. It is particularly useful for those who prefer having spare parts on hand so a burnt-out bulb does not interrupt evening time outdoors.

Those who should look elsewhere are buyers seeking a universal bulb for many different zapper brands or people who want an integrated replacement unit that includes grid cleaning features; this product is a straight replacement lamp tailored for the Flowtron BK-15 model.
