Osram Vintage 1906 Globe Gold E27 3.4 W – spiral filament, 470 lm

It cannot. In the product information, the bulb is clearly marked as non-dimmable. If there is a dimmer in the light fixture, the bulb may flicker, buzz, or be damaged prematurely. For a dimmable light fixture, it is recommended to choose a model specifically marked as dimmable.

A spiral filament means that the LED filament wire is coiled inside the bulb instead of being a straight wire. When lit, it appears through the glass as a twisting glowing line, which is the whole point of the lamp: it is intended to be seen, not hidden under a lampshade. The golden glass softens the hue of the glow to be warmer.

It is clearly larger than a standard bulb: its 95 mm diameter is roughly the size of a large apple, and the total length is 139 mm. A standard E27 bulb has a diameter of 60 mm. Therefore, measure the available space in your light fixture before ordering, especially if the bulb will be placed inside a lampshade or cover.

Not on its own. 470 lumens is equivalent to a 40-watt incandescent bulb, meaning the lamp provides ambient light and highlights itself as a decorative element. If you also need sufficient general lighting, use multiple lamps or supplement the lighting with other light sources. The primary purpose of a decorative lamp is to look good.
