G9 LED bulb, 6000K

For anyone replacing a G9 halogen bulb in a chandelier or another listed fixture, this LED version offers a bright, cool daylight colour and a lower stated wattage. It produces 400 lumens while using 4W, compared with the 40W halogen equivalent described in the listing. The ceramic body and transparent PC shade are practical details, but the key buying question is whether a 6000K light suits the room: it is a cool white rather than a warm, soft glow.

Technical details

The bulb is rated at 400 lumens and 6000K, with a colour rendering index above 82. Its stated power use is 4W, and the listing compares it with a 40W halogen bulb, claiming 90% energy savings. It is described as dimmable, instant-on, and free from flicker and buzzing. The body is white ceramic, with a transparent PC shade, the listing attributes heat dissipation to the ceramic construction and gives a lifespan claim of over 30,000 hours, plus a two-year warranty.

Those are listing claims, not a guarantee of how long an individual bulb will last in every fixture. One limitation is the colour temperature: 6000K can look stark beside warmer bulbs, so matching the existing lighting matters if you want a consistent feel across a room.

Compatibility

The G9 fitting is the defining compatibility detail. The listed uses include crystal chandeliers, pendants, table and floor lamps, wall sconces, ceiling fans, bathroom and vanity lights, and under-cabinet lighting. For a quick visual check, compare the G9 bulb currently in a chandelier with the replacement before fitting it, the product information does not give dimensions, so it does not confirm clearance for every enclosed or compact fixture. It also does not name compatible dimmer models. If you plan to use dimming, the bulb’s dimmable label alone does not establish that it will work with a particular dimmer.

Usage tips

Choose this bulb where a bright, cool-white effect is wanted, such as task lighting or a fixture where daylight colour is preferable to a warmer ambience. A cluster of matching bulbs in a chandelier will keep the colour more consistent than mixing 6000K LEDs with warm-white bulbs. Its 4W rating may appeal when replacing a 40W halogen, but compare the light output as well as wattage: the stated brightness is 400 lumens, which may not suit a fixture that needs stronger illumination.

It’s a good option if you need a G9 replacement, prefer cool daylight colour, and want the lower stated power use. It may not suit you if you’re aiming for a warm, cosy light or need confirmed compatibility with a specific dimmer.

Buying questions

Does it replace a 40W halogen? The listing describes it as a 40W halogen equivalent, with 400 lumens from 4W. Check that this brightness suits the fixture and the job.

Can it be dimmed? It is described as dimmable, but no particular dimmer compatibility is provided. If dimming is essential, that missing detail matters.

What colour of light does it give? It is rated at 6000K, described as cool daylight white. That is a different look from warm-white lighting.

Before buying

This G9 bulb makes most sense as a like-for-like fitting replacement when you want cool, bright light and the stated 400-lumen output is enough. It is a less convincing choice for a softly lit living space or a setup where the exact dimmer match is important. Check the socket, available space and desired light colour against the bulb you are replacing, the product details do not provide dimensions or specific dimmer pairings.
