Description
This is a smart GLS bulb with a clear glass body and a spiral LED filament that coils round a slim central stem, finished with a black collar and a silver-coloured E27 screw cap. It is 12cm long and 6cm in diameter, so it suits any fitting that takes an E27 cap and has room for a bulb of that size. The light is RGBW, which means coloured light as well as white, and its warm white sits at 3000K for a cosy, familiar glow. It draws 4.9W and gives 400lm. The bulb is rated IP20, so it belongs indoors in dry rooms, never outdoors or near water.
Because the glass is clear and the filament is on show, this bulb looks its best in an open pendant, a bare cord set or a lamp with an open shade, where the coiled filament becomes part of the look. It suits a living room, a bedroom, a dining area or a home office, anywhere a softer, adjustable light earns its place. At 400lm it gives a gentle level of light, so we would choose it for mood and accent lighting rather than as the only light in a large room. Switching between warm white and colour from the app lets you set a calm evening glow one night and a splash of colour for a party the next.
It is controlled by app and it is dimmable, so you can bring the brightness down whenever the room calls for it. It also works with a remote control, which is sold separately and does not come in the box. The bulb runs on 220-240V, 50/60Hz mains, carries energy class G and weighs 0.065KG packed. A practical note before you buy: because the glass is clear, pick a shade or pendant that leaves the bulb on view, so the spiral filament and its colours are what people notice first.
