Description
This is a GLS bulb in the familiar household pear shape, built with LED filaments rather than a coiled tungsten wire. Four straight filament strips run the length of the clear glass, so lit or unlit it looks like a traditional bulb, and the glass is left clear rather than pearled. It draws 8W and gives 1050 lumens, which the pack rates as the equal of a 75W conventional bulb. The cap is E27, the large screw fitting known in the trade as ES, and the light is warm white at 2700 Kelvin.
A clear filament bulb is worth choosing where the bulb itself is on show: open pendants, a glass shade, a wall bracket with the lamp exposed, or a table lamp under a fabric drum. The 280 degree beam spreads light almost all the way round, so a pendant lit with one of these will fill a room rather than throw a pool straight down. At 1050 lumens it is bright enough to be the main light in a bedroom, hallway or dining room, and the 2700K tone keeps the light soft and yellow rather than clinical.
This one is not dimmable, so pair it with a plain on/off switch; on a dimmer circuit a non-dimmable lamp can flicker or hum. The pack prints a 10 year, 10,000 hour lamp life and more than 8,000 on and off switching cycles, which matters on a hall or landing light that gets flicked constantly. Energy class is E, and the rating is IP20, for dry indoor use. Each listing is a single bulb with a minimum order of five, sold in multiples of five. It sits alongside our wider range, including a 7W E27 GLS filament in the same warm white 2700K.

Frequently Asked
How do I know my light fitting takes an E27 cap?
E27 is the larger of the two screw caps used in the UK, also written ES. Take the old bulb out and measure the screw thread: 27mm across means E27, while 14mm is the smaller E14 or SES.
Can I use this on a dimmer switch?
No. The specification lists it as non-dimmable, so run it from a standard on/off switch. Fitted to a dimmer circuit a non-dimmable lamp may flicker, buzz or fail early, even at full brightness.
How bright is 1050 lumens in practice?
The pack rates it as the equal of a 75W conventional bulb, so it is a main-light output rather than a background one. In a bedroom or hallway it will comfortably light the whole room from a single central fitting.
What does warm white 2700K actually look like?
2700K is the soft yellow tone people associate with old filament lamps. It flatters wood, brick and warm paint colours, and suits living rooms and bedrooms far better than a bluer 4000K or 6500K light.
Will the light spread properly inside a shade?
The beam angle is 280 degrees, so light leaves the bulb in nearly every direction rather than in a cone. That suits drum shades, glass pendants and open lanterns where you want an even glow.
Does it run on normal UK mains?
Yes. It is rated for 220-240V supply, which covers UK household mains, and it fits any standard E27 lampholder without an adaptor, driver or separate transformer.
