Energizer 4W G80 Dimmable LED Globe Filament Smokey Bulb - Cool White E27 4000K

The Energizer G80 is an 80mm globe bulb with a smokey glass finish and visible LED filament strips inside, combining the look of vintage incandescent filament bulbs with modern LED efficiency. The bulb delivers 400 lumens of cool white 4000K light from a 4W LED assembly behind an E27 screw base, replacing traditional 40W incandescent globes in pendant fittings, open ceiling roses and table lamps where the bulb itself forms part of the visual design.

Designed for installation in kitchens, bathrooms, workspaces and commercial hospitality settings where crisp visibility is needed, the 4000K colour temperature sits between warm white and daylight, providing clear illumination without the yellow cast of 2700K bulbs or the clinical tone of 6000K daylight equivalents. The dimmable function allows the bulb to be paired with compatible LED dimmers to lower output for ambient lighting or raised to full 400 lumens for task visibility.

The smokey tinted glass softens the brightness of the LED filament strips when viewed directly, reducing glare in open pendant fittings and giving the bulb a mid-century aesthetic that pairs with both industrial metal fittings and polished brass or chrome fixtures. The G80 globe shape measures 80mm in diameter and 123mm in total height including the E27 base, making it suitable for medium to large pendants, wall sconces and table lamps with sufficient shade clearance.

Energizer rates the bulb with a G energy efficiency rating under the updated EU scale and a 15-year lifespan claim based on 3 hours daily use. The 320-degree beam angle provides near-omnidirectional light distribution typical of globe bulbs, with minimal rear shadowing from the internal circuit board.

Is this bulb compatible with dimmer switches?

Yes. The Energizer G80 is rated as dimmable and will work with most LED-compatible trailing-edge dimmers. Performance varies by dimmer model — some older dimmers designed for incandescent bulbs may cause flickering at low settings. For best results, use a dimmer specified for LED loads.

What does 4000K cool white look like compared to warm white?

4000K produces a neutral to slightly cool white light that appears crisper and brighter than the yellow-toned 2700K warm white typically used in living rooms. It works well in kitchens, bathrooms and workspaces where task visibility is needed, but may feel too clinical for relaxed evening settings where warmer tones are preferred.

Will the smokey glass reduce the light output?

The smokey tint softens the visual brightness of the LED filaments when viewed directly, but the rated output is 400 lumens as specified — the tint is accounted for in that figure. The main effect is aesthetic, reducing glare in open fittings rather than significantly dimming the room.

What size pendant shade does this bulb suit?

The G80 measures 80mm in diameter and 123mm in total height. It suits medium to large open pendants, vintage-style wire cage fittings, and table lamp harps with at least 150mm clearance from the socket to the top of the shade. Check your fitting dimensions before ordering.
