Pros and cons

Pros

Four bulbs in the listed pack, useful when replacing several lamps with the same warm colour.
The dimming option gives more control over ambient light when paired with a compatible trailing-edge dimmer.
The E27 base and compact globe form are listed for fixtures such as chandeliers, ceiling fans and decorative lamps.

Cons

The stated 450-lumen output is modest for buyers who need strong task or room-wide illumination from one bulb.

What to know before buying

Listing details to confirm

The title identifies the bulbs as G45, while technical details give A15 for bulb shape size and elsewhere list Globe(G). The title says 2700K and the detail fields also list warm white, but the listing's claim of 450 lumens and 40W equivalence is not independently verified. The stated 230 Volts differs from the accepted range of 100 to 240 Volts. The listing also names infrared connection and push-button controls without explaining their role for a bulb. Confirm the physical shape and dimmer compatibility for your fixture. The manufacturer warns against incandescent or halogen dimmers and three-level dimmer switches.

Frequently asked questions

Can these bulbs be dimmed?

The listing describes them as dimmable with compatible trailing-edge dimmers. It says not to use incandescent or halogen dimmers or three-level dimmer switches.

What fitting do they use?

The listed base is E27. Check the bulb's physical shape against your fixture because the listing calls it G45 in the title but gives A15 in its shape-size details.

How bright are the bulbs?

The listing states a maximum output of 450 lumens per bulb and a 40W incandescent equivalent. These are listing claims rather than independently verified measurements.

How many bulbs are included?

The product title and item count state a four-pack.
