Dichroma 41050 7W UV Replacement Bulbs for Dynatrap — 4-Pack, 3,000‑Hour Life

Dichroma 4 Pack 41050 7-Watt UV replacement bulbs are direct-fit tubes designed to restore UV attraction in compatible Dynatrap mosquito traps, helping your trap perform like new.

When your Dynatrap starts catching fewer insects, the culprit is often a dim or burned-out UV lamp. These Dichroma bulbs are sized and powered to match common Dynatrap models so you can swap tubes quickly and keep glue boards and mechanical components doing their job. They’re sold as a four-pack and rated for long run times, making them a convenient replacement option for seasonal or year-round use.

Which Dynatrap models work with these Dichroma bulbs?

These 7W 41050 bulbs are compatible with several Dynatrap mosquito trap models that use the same tube length and connector style. Check your trap’s manual or the existing tube’s markings before ordering to confirm fit. They are not intended to function as an independent trap; they replace the UV light inside a unit.

• Compatible models: DT1050, DT1100, DT1210, DT1250, DT1260
• Same size and connector style as OEM 41050 7W tubes
• Do not use these bulbs outside an enclosed trap housing

How long will each replacement bulb last, and when should I change them?

Each Dichroma tube is rated for up to 3,000 hours of continuous operation, which commonly equals about four months of nonstop use. Actual life depends on how frequently the trap runs and environmental factors; dimming or a noticeable drop in catches signals it’s time to replace the tube. Replacing the bulb on schedule keeps the trap’s adhesive boards and airflow systems performing efficiently.

• Rated life: up to 3,000 hours (approx. 4 months continuous)
• Replace when lamp output visibly dims or captures decline
• Routine seasonal replacement recommended for consistent performance

What insects do these UV bulbs help attract, and how do they work with the trap?

The bulbs emit ultraviolet light frequencies attractive to a range of flying pests such as mosquitoes, gnats, and certain moths; once drawn in, insects are captured on glue boards inside the trap. The bulbs themselves don’t kill insects chemically—they provide the visual stimulus that lures pests into the Dynatrap’s capture chamber. For optimal results, use fresh glue boards and maintain the fan and collection area.

• Attracts mosquitoes, gnats, small moths and other flying insects
• Works with glue boards inside the unit—no insecticide in the bulb
• Best results when combined with clean glue boards and functioning fan

What should I know about handling, installation, and warranty?

The light tubes are glass and fragile, so handle carefully during installation—avoid dropping or applying sideways pressure. If a bulb arrives broken or fails early because of shipping damage, contact the seller for a replacement. Dichroma provides after-sales support for product issues and can help troubleshoot fit or operation questions.

• Fragile glass tube—handle with care during replacement
• Contact seller for replacements if damaged in transit
• After-sales support available for fit and function questions

Who is this for? Dichroma’s 4 Pack 41050 7W UV replacement bulbs suit homeowners, property managers, and anyone who already uses compatible Dynatrap models and wants to maintain steady insect capture without switching trap brands. They’re ideal for people who prefer straightforward part-for-part replacements, seasonal maintenance shoppers ordering multiple bulbs at once, and users who want reliable, commonly sized tubes to keep outdoor living areas, patios, and light-commercial spaces more comfortable during insect season.
