E27 LED Filament GLS Bulb 8W 1050lm - Warm White 2700K - Energizer

A clear GLS bulb on an E27 screw cap: the familiar pear shape that has lit British homes for a century, rebuilt around LED filaments. Slim filament strips stand upright inside the clear glass, so it reads as a traditional bulb when it is off and glows much the same way when it is on. It draws 8W and puts out 1050 lumens, and the Energizer pack rates that as a 75W replacement. The light is 2700K warm white, the soft yellow tone people associate with old incandescent bulbs rather than anything crisp or blue.

Because the glass is clear, the filaments are part of the look, so this suits fittings that leave the bulb on show: an open pendant over a dining table, a bare flex in a hallway, a table lamp with a slim or partly open shade. The 320 degree beam angle matters here too: light leaves almost the whole surface of the glass, upward as well as down, so it fills a room rather than throwing a pool onto one surface. It sits just as happily inside a closed shade, though you lose the filament detail that makes a clear bulb worth choosing in the first place.

This one is not dimmable, and the pack marks it that way, so put it on a plain on/off circuit and choose a dimmable bulb where a dimmer is fitted. The energy label gives class E, drawing 8 kWh per 1000 hours. The pack prints a 15,000 hour lifespan, expressed there as 15 years. Each unit is a single bulb, sold in multiples of twelve with a minimum order of twelve, which is worth knowing if you are stocking up for a whole house. It sits alongside our wider range of LED bulbs in candle, golf and GU10 forms.

Which light fittings take this bulb?

Any fitting with an E27 Edison screw socket, the larger of the two common screw sizes, where E27 refers to a 27mm thread. Check the cap on the bulb you are replacing.

Can I use it on a dimmer switch?

No. This bulb is non dimmable and the pack marks it so, meaning it belongs on a plain on/off circuit. Choose a dimmable lamp for any dimmed light.

How bright is 1050 lumens in everyday terms?

The pack rates it as a 75W replacement, so it is bright enough for a main ceiling light or a well used reading lamp in a living room.

What does 2700K warm white actually look like?

It is the soft, slightly yellow light of a traditional incandescent bulb, comfortable in living rooms and bedrooms rather than the crisp blue-white of a daylight lamp.

Will the filaments show in an open shade?

Yes. The glass is clear rather than opal, so the upright filament strips are on view whenever the bulb is exposed, which is the point of a filament lamp.

How many bulbs will I receive?

Each unit is a single bulb. The minimum order is twelve units, sold in multiples of twelve, so a first order brings twelve bulbs in total.
