DynaTrap 21050 9-Watt UV Light Bulb Replacement for Indoor FlyLight DT3009/DT3019/DT3039

Keep your indoor FlyLight performing at its best

Premium replacement bulbs can help you maintain an efficient, low-maintenance indoor pest solution. The DynaTrap 21050 is a 9-watt UV bulb designed for use with the FlyLight models DT3009, DT3019, and DT3039. When powered by the AtraktaGlo UV light, flying insects are naturally drawn toward the trap, helping you reduce nighttime swarms in kitchens, living rooms, or home offices. The compact bulb is built for continuous use and is color-matched to blend with standard indoor lighting—white when lit and unobtrusive when off.

What this bulb does for your indoor space

The AtraktaGlo UV light is a key component of the DynaTrap system, providing a targeted lure for flying insects. By pairing this bulb with your FlyLight, you can create a steady, passive defense that operates quietly in the background, helping to reduce nuisance buzzing and the need for frequent manual cleaning.

Indoors, the FlyLight traps cover up to 600 square feet, making this replacement bulb suitable for living rooms, bedrooms, kitchens, and small offices. The compatibility with DT3009, DT3019, and DT3039 models ensures you can keep the same reliable setup as your space evolves.

Replacement guidance and best practices

Even when the bulb light remains visible, its ability to attract insects gradually declines over time. For consistent performance, consider replacing the bulb after about 3,000 hours of use (roughly four months of typical operation). Keeping a spare on hand helps you avoid downtime and maintain continuous protection.

Each package includes two 9-watt bulbs, so you’re prepared for routine maintenance or a quick swap when needed. The bulbs measure 6 inches long with a compact 1.75-inch square cross-section, designed to fit neatly inside the FlyLight housing.
