[Lifetime Warranty] 26W 3U 43050 4 Pin Base Bulbs

43050 26W 3U UV Replacement Bulb - Pack of 4

Key Features

• 365nm-368nm UV-A Output:Specifically engineered to emit the precise ultraviolet wavelength that is most attractive to mosquitoes, flies, moths, and other phototactic flying insects.
• 3U Triple-Tube Design:Features a high-surface-area 3U (triple U-bend) fluorescent tube architecture that maximizes UV light dispersion, ensuring consistent 360-degree attraction.
• GX24q-3 4-Pin Base:Equipped with a standard 4-pin push-in base (plug-and-play) for a secure electrical connection and easy installation without the need for tools.
• Ti02 Synergistic Attraction:Optimized to work in conjunction with the Titanium Dioxide (Ti02) coated surface of your trap to produce the CO2 trail that mimics human breath.
• Extended 3,000-Hour Lifespan:Designed for continuous 24/7 operation; provides approximately 4 months of peak attraction power before the UV effective wavelength begins to degrade.

Replaces / Cross-Reference Part Numbers

Compatibility & Fitment

• DynaTrap DT1750:Direct replacement for the 3/4 Acre Decora series traps.
• DynaTrap DT1775:Direct fit for the 1-Acre Decora series high-output traps.
• Industrial/Commercial Use:Compatible with various large-scale indoor and outdoor insect trapping units that specify a 26W 4-pin triple-tube UV-A lamp.
• Note:While the bulb may physically fit some other sockets, it is specifically calibrated for the ballasts used in the DT1750 and DT1775 series to ensure the correct UV-A intensity.

When to Replace

• Diminished Catch Rate:If your trap is catching significantly fewer insects than usual, the UV coating inside the bulb may have degraded, even if the bulb still appears "lit."
• Flickering or Darkened Ends:Heavy blackening at the base of the glass tubes indicates the bulb is nearing the end of its life and should be replaced to prevent ballast strain.
• Seasonal Maintenance:For best results, bulbs should be replaced every 4 months (approx. 3,000 hours) to ensure the light output remains within the specific 365nm-368nm attraction window.

Installation Tips

• Safety First:CRITICAL:Always turn the power switch to "OFF" and unplug the unit before servicing. Allow the old bulb to cool for at least 10 minutes to avoid burns.
• Accessing the Bulb:On most DT1750/1775 models, you must remove the retaining cage and the light housing fasteners (usually black threaded pieces) to reach the bulb assembly.
• Protective Handling:PRO TIP:Use a clean cloth or glove when handling the new bulb. Oils from your skin can create "hot spots" on the glass, which may lead to premature bulb failure.
• The "Click" Lock:Ensure the 4 pins are aligned correctly with the socket. Press firmly until you feel or hear the bulb seat into the silver clips. A loose connection will prevent the bulb from firing or cause it to flicker.
• Clean the Socket:Before inserting the new bulb, use a soft, dry brush to remove any dust or dead insect debris from the socket area to ensure a clean electrical contact.
