Qualirey T8 Bug Zapper Replacement Bulbs 8‑Pack — 13" 10W black & white UV tubes for broad‑spectrum insect attraction

Qualirey 8 Pcs T8 13" 10W replacement tubes are a set of four black UV and four white attractor fluorescent bulbs designed to drop into compatible T8 bug zappers and help reduce flying insects indoors and outdoors.

These glass fluorescent tubes come as a matched kit of 13-inch, 10-watt T8 bulbs: four black-light tubes tuned around 365 nm and four white-attractant tubes covering roughly 280–480 nm. Built for common electronic insect-trap fixtures, the pair of tube types broadens the wavelengths that attract different species while using traditional fluorescent technology for steady UVA output. The kit is intended as a direct swap for many 20W-equivalent electronic exterminator housings and works in living spaces, patios, campsites and other everyday settings.

Which insects do the black and white tubes target?

Each tube type favors a different attraction strategy: the black tubes emit concentrated UVA near 365 nm that appeals to moths, flies and other nocturnal fliers, while the broader-spectrum white tubes produce visible violet-blue light that entices a wider variety of mosquitoes and flying pests. Using both types together increases the chances of luring multiple species into a trap.

• Black tubes: focused 365 nm UVA for moths, certain flies and night‑active insects
• White tubes: 280–480 nm spread to attract mosquitoes and mixed species
• Combined use: broad-spectrum attraction across daytime and nighttime pests

How do I install these T8 replacement bulbs safely?

Installation is straightforward: cut power to the unit, remove the old tube, seat the new T8 tube into the fixture’s slots, and restore power to test. Because the tubes are glass, handle them carefully and avoid forcing the pins; follow the zapper manufacturer’s instructions for your specific model.

• Turn off and unplug the device before removing old tubes
• Align T8 pins with the fixture sockets and rotate or press gently into place
• Test after power is restored and allow a brief warm-up for full UVA output

How durable and safe are these fluorescent replacement tubes?

The bulbs are made from glass fluorescent tube construction intended to deliver consistent UVA energy over extended use. They don’t emit chemical vapors or ozone and operate silently, making them suitable for bedrooms and shared spaces; still, treat the glass as fragile and replace any cracked tubes promptly.

• Glass construction for stable UVA output and longer usable life than some plastic alternatives
• No chemical emissions—light-based attraction only
• Quiet operation—no fan or motor noise from the tubes themselves

Will these bulbs work with my existing trap or outdoor setup?

Qualirey T8 13" 10W tubes are compatible with many electronic insect traps that accept 13-inch T8 fluorescent tubes, especially units designed for 20W fixtures. Confirm socket type and physical length before purchasing to ensure a correct fit.

Who is this for: The Qualirey 8-piece pack suits homeowners, small-business operators and outdoor hobbyists who already own T8-style electronic insect traps and want a ready supply of matched replacement tubes. It’s useful for anyone seeking broader wavelength coverage—both UVA and visible violet-blue—without adding noisy components or chemical agents. Ideal for bedrooms, kitchens, patios, campsites and commercial spaces that accept 13-inch T8 fluorescent tubes, the set gives you four black and four white bulbs to swap multiple fixtures or keep spares on hand.
