YUIIP G9 4W LED Bulb, 3000K Warm White, 400 Lumens, 6-Pack

Practical tips

For a crystal chandelier, wall sconce or table lamp with a G9 socket, these YUIIP LED bulbs provide warm white light in a compact bi-pin format. Each bulb uses 4 watts and delivers 400 lumens, making the six-pack useful when you’re replacing several bulbs or keeping matching spares for indoor fixtures.

The G9 base is designed for G9 sockets, and the listed operating voltage is AC 110–130V. The bulb is non-dimmable, so use it in a fixture without a dimmer. It is a little larger than a traditional halogen bulb, compare the bulb’s shape with the available space in the fixture before fitting it.

Want a warm tone without the usual wait for a bulb to brighten? The 3000K colour temperature and instant-on feature make this a practical choice for everyday indoor lighting.

Why it makes sense

Compared with replacing G9 halogen bulbs with another halogen, this LED option uses 4 watts while providing light output described as equivalent to a 40-watt halogen bulb. That gives you a lower-wattage replacement for compatible fixtures, while the 360-degree beam spreads light around the bulb rather than focusing it in one direction. A ceramic base, transparent cover and stated CRI of 83 round out the practical details for home lighting.

The warm white output suits rooms where a softer tone is preferred, including living areas, bedrooms and accent lighting. Use the bulbs in a G9 chandelier for an even look across its multiple light points, or in a compatible wall or table lamp for local illumination. The instant-on design is handy in frequently used spaces, while the six-bulb pack makes it easier to replace a group of matching bulbs together.

Buyers commonly describe installation as straightforward and the 3000K colour as consistent with expectations. Feedback about lifespan is mixed: some report bulbs lasting well, while others say theirs stopped working sooner than expected. The stated operating life is up to 30,000 hours, individual experiences can vary.

Questions before you buy

Will these bulbs fit my light fixture? They have a G9 bi-pin base and are intended for G9 sockets. The bulb is a little larger than a traditional halogen bulb, so check that the fixture has enough room for its shape.

Can I use them with a dimmer? No. These bulbs are non-dimmable and should be used in a fixture without a dimmer.

What kind of light do they produce? Each bulb provides 400 lumens of 3000K warm white light, with a 360-degree beam angle. They are intended for indoor lighting.

Final verdict

For anyone updating indoor G9 fixtures, this six-pack combines a familiar warm-white tone with 400 lumens per bulb and 4-watt LED operation. Choose it for compatible chandeliers, sconces or lamps when you want instant-on, all-around light and do not need dimming.
