Replacement UV Bulb for Bug Zappers

This 15 watt U-shaped twin-tube bulb fits compatible indoor and outdoor insect traps. It uses a 4-pin base for a secure connection and emits ultraviolet light to attract flying pests. The compact lamp measures 22 centimetres in height and 7.7 centimetres in width.

Practical Limits of UV Attraction

The bulb operates at a 365 nanometre wavelength and 60Hz frequency to lure insects effectively. Coverage extends up to 1000 square feet when installed in a suitable zapper unit. It requires a fixture with an internal 4200V grid to eliminate pests on contact. Performance depends on the surrounding trap housing and power supply.

Deciding Specification: Wattage and Base Type

Match the 15 watt rating and 4-pin base exactly to your device specifications before purchase. An incorrect wattage or pin configuration will prevent the bulb from lighting or seating properly. This single compatibility check determines whether the part will function in your existing unit.
