E27 GLS 7.8W Filament ST64 75W-eq LED Bulb 320° 1055lm - Cool White

This E27 filament LED bulb gives the vintage look of visible glowing filaments inside clear ST64 glass, while drawing just 7.8 watts. It screws into a standard E27 Edison Screw (ES) holder, the cap US buyers know on a classic household light bulb. Output is 1055 lumens at 4000K cool white, with a Ra 80 colour rendering and a wide 320 degree spread, so light travels almost all the way around the bulb rather than in one direction.

At 7.8W the bulb replaces an old 75W incandescent, so it suits open fittings where the filaments are on show, such as pendants over a kitchen island, hallway and landing fittings, or exposed-bulb wall and table lamps. The 320 degree beam throws light evenly across a room rather than spotting one area, giving a crisp, bright cool white that reads as clean daylight-leaning light for living rooms, dining areas and work corners. It is for dry indoor use only and should be kept clear of bathrooms, porches and any outdoor or damp position.

The bulb measures Ø64 by 140 mm and weighs 40 g, running on 220 to 240V AC mains through the integrated E27 cap with no separate driver needed. The clear transparent glass keeps the filament detail visible, and at 135 lm/W it is an efficient way to light a fitting, rated for 25,000 hours of use. Please note this filament bulb is non-dimmable and runs at a fixed output. Our wider E27 filament range includes other shapes and tones if you need to match several fittings.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It uses an E27 Edison Screw (ES) cap, the larger screw-fit standard found on most pendants, table lamps and ceiling fittings. Simply screw it in the same way as the bulb you are replacing. US buyers should note E27 is the equivalent of the standard medium screw base.

What old bulb wattage does it replace?

The LED draws only 7.8W but gives 1055 lumens, which matches the brightness of an old 75W incandescent bulb. The 7.8W figure is the actual power it uses, so it cuts running costs while keeping the same light level. It is rated for around 25,000 hours of use.

Is this bulb dimmable?

No, this is a non-dimmable bulb that runs at a fixed output. Using it on a dimmer switch may cause flicker or buzzing and is not recommended. If you need dimming, choose a bulb listed as dimmable instead.

What does the cool white colour look like?

At 4000K it is a cool white, a clean and bright tone that leans towards daylight without being harsh. It works well in kitchens, hallways and work areas where you want clear, crisp light. The Ra 80 colour rendering keeps everyday colours looking natural.
