DiCUNO G9 LED Bulbs, 4W, 4000K Natural White, 400 Lumens, 10-Pack

A softer, warmer atmosphere and clear task lighting call for different kinds of light. These DiCUNO G9 LEDs give indoor fixtures a natural-white 4000K glow suited to spaces where you want bright, even illumination. Each bulb uses 4W and produces 400 lumens.

Usage tips

Use these bulbs in indoor fixtures designed for a G9 bi-pin base and 120V bulbs. Their compact format is intended for common G9 replacements in fittings such as wall sconces, chandeliers, floor lamps and table lamps, check the fixture’s available space and socket before installing. They are non-dimmable, so use them with a standard on/off control rather than a dimmer. For a kitchen work area, bathroom vanity or dining space, the 4000K natural-white light provides a clean, bright look. The 360-degree beam angle helps spread light around the bulb rather than concentrating it in one direction.

Pros

The 4W LED output is rated at 400 lumens, equivalent to a 40W halogen bulb, making this a practical choice when replacing compatible G9 halogens while using less power per bulb. A 10-pack is useful when several fixtures need the same light colour, or when you want matching bulbs for a room. The ceramic base and PC construction are designed for everyday household lighting, while a stated operating life of up to 25,000 hours can mean fewer replacement changes over time.

Buyer feedback commonly highlights the brightness and neutral-white appearance, with some noting that the bulbs light kitchen spaces effectively and fit their fixtures. This complements the stated 400-lumen output and 4000K colour temperature, while keeping the choice grounded in the type of light the bulbs are designed to provide.

Questions before you buy

Will these bulbs work with a dimmer? No. They are non-dimmable, so use them in a fixture controlled by a regular on/off switch.

What socket do they fit? They use a G9 bi-pin base. Match that base to your fixture and check the available space so the bulb fits properly.

What kind of light do they produce? Each bulb produces 400 lumens of 4000K natural-white light, with a 360-degree beam angle. That makes them suitable for indoor spaces such as kitchens, bathrooms and dining areas where clear, evenly distributed light is useful.

Should you buy it?

A solid pick if you need several matching G9 bulbs for indoor fixtures and want natural-white light without choosing a dimmable setup. The 10-pack, 4W consumption and 400-lumen output make this DiCUNO set a straightforward fit for compatible household lighting, from a single room refresh to replacing bulbs across multiple fixtures.
