Wiyifada A19 LED Black Light Bulbs, Dimmable 9W, 385–400nm UVA, 2-Pack

For parties, Halloween displays, or body art that call for a fluorescent blacklight effect, these Wiyifada bulbs provide UVA output in the 385–400nm range. Their A19 shape and E26 base fit standard E26 medium-base sockets. The two-bulb pack makes it easy to set up blacklight lighting in more than one fixture.

What stands out

The 385–400nm UVA wavelength is designed to bring out the fluorescent effect in reactive pigments, paints, and dyes. That makes these bulbs a natural fit for glow-in-the-dark decorations, body paint, and themed party spaces. A 150-degree beam angle spreads the light across an area, helping illuminate a display rather than concentrating it in a narrow spot.

Each bulb uses 9 watts and is listed as a replacement for a traditional bulb up to 100 watts. The dimmable feature gives you another way to adjust the atmosphere for a setup, while the two-pack lets you place blacklight illumination in separate areas. Buyers often praise the purple-toned look and the way the bulbs activate fluorescent Halloween props, comments on brightness and longevity vary, so individual experiences should not be treated as a performance guarantee.

What to know

These are A19 LED blacklight bulbs for indoor use, with a standard E26 base and 120V input. They are made for fixtures with an E26 medium socket, so installation is a simple screw-in replacement when the fixture matches those requirements. The stated operating life is 20,000 hours. Their blacklight output serves a different purpose from a standard white room bulb: choose them when you want fluorescent materials to stand out, rather than general-purpose white illumination.

Everyday use

Use the pair to create a coordinated effect across a Halloween display, party room, body-art area, or other indoor space with reactive pigments. For example, placing bulbs in E26 fixtures around a display can help bring glow-in-the-dark props into the overall scene. They are also listed for settings such as Christmas décor, aquariums, bands, and body art. Keep the choice focused on the effect you want: a regular LED is intended for everyday visible lighting, while these bulbs are designed for blacklight ambiance.

Practical questions

What socket do these bulbs use? They have an E26 base, also called a standard medium base, and are intended for matching E26 fixtures.

What makes fluorescent decorations glow? The bulbs emit UVA light at 385–400nm, which creates a fluorescent effect with reactive pigments, paints, and dyes.

Can the light level be adjusted? The bulbs are listed as dimmable, offering an adjustment for the lighting atmosphere in a compatible setup.

Should you buy it?

Choose this two-pack if your project calls for indoor blacklight rather than ordinary white lighting. The 385–400nm UVA output, 150-degree beam angle, dimmable feature, and E26 fit make it a practical match for parties, Halloween props, and other displays using fluorescent or glow-in-the-dark materials.
