Replacement Blacklight Bulb for Flowtron Bf-190 Insect Killer - 40 Watts, T8 Tube, G10Q-4 Base

Replacement for FLOWTRON BF-190, this 40-watt T8 blacklight tube restores the insect-attracting output of your trap or zapper. It matches the original lamp's electrical rating and the G10Q-4 base, so it installs in place of the factory bulb with no modification, and it produces the ultraviolet output that draws mosquitoes, flies and other flying insects into the unit's kill grid or trap.

Key Features & Benefits

• Direct cross-reference replacement for the FLOWTRON BF-190 lamp, matching the original electrical and physical format
• Emits light in the 350-370 nanometer UV-A range, the wavelength band that flying insects see most strongly and are naturally drawn toward
• Restores full attraction power to an insect trap or zapper whose output has faded - UV phosphors degrade long before a tube stops glowing
• Suited to season-long residential and commercial duty, indoors or in covered outdoor fixtures

Product Specifications

• Wattage: 40 watts
• Tube type: T8
• Base: G10Q-4 square 4-pin
• Light output: UV-A blacklight (350-370 nanometer UV-A)
• Cross-reference part number: FLOWTRON BF-190

Whether the unit protects a backyard patio, a barn, a restaurant patio or a loading dock, consistent UV output is what keeps it earning its place. A trap running on a tired lamp gives the impression of working while the insect count climbs, which is why manufacturers recommend a fresh tube at the start of every bug season rather than waiting for a visible failure. Keeping a spare on the shelf also means a burned-out or shipping-damaged tube never sidelines the unit during the weeks it matters most.

Replacement Compatibility

This lamp serves as a replacement for the FLOWTRON BF-190 and fits Flowtron BK-40 and BK-40D zappers, with equivalent 40-watt U-shape lamps also used in Flowtron BK-80D, FC-7600 fly killers, Stinger B4040-class units and Black Flag BZ-40/BZ-40DX zappers. Always match the wattage, tube shape and base of the lamp being replaced; if your fixture's model number is not listed, compare it against the specifications above before ordering.
