Description

The Energizer 4W LED GLS is a gold-tinted filament bulb with a visible LED filament arrangement inside the glass, designed to mimic the appearance of traditional carbon-filament incandescent bulbs while running on 4W of power. The B22 bayonet cap fits standard UK lamp holders, and the bulb outputs 320 lumens at 2700K warm white, roughly equivalent to a 30W incandescent in brightness but with significantly lower heat generation.

Intended for decorative fixtures where the bulb itself is visible — pendant lights, wall sconces, table lamps with open shades, exposed-bulb chandeliers — the gold tint on the glass softens the light output and gives the bulb a vintage aesthetic when lit or unlit. The filament layout inside follows the classic incandescent pattern, arranged in vertical loops that glow amber-gold when powered. This makes the bulb itself part of the room's design rather than just a functional component hidden inside a shade.

The bulb measures 60mm diameter and 117mm height, which is standard GLS (general lighting service) sizing and will fit most medium-sized lamp holders without clearance issues. At 320 lumens the output is intentionally modest — this is accent and mood lighting rather than task lighting. The 2700K colour temperature sits at the warmer end of the white spectrum, casting a slight amber tone that pairs well with timber, brass and warm-toned interiors. The bulb is non-dimmable and carries an Energy Rating of G under current UK labelling, reflecting the trade-off between decorative filament design and absolute energy efficiency.

Frequently Asked

Is this bulb dimmable?

No. The bulb is non-dimmable and must be used with a standard on/off switch. Pairing it with a dimmer circuit may cause flickering or failure.

What does the gold tint do to the light output?

The gold-tinted glass softens the light and gives it a slightly warmer amber cast compared to a clear-glass bulb at the same 2700K rating. This enhances the vintage aesthetic and reduces glare when the bulb is visible in open fixtures.

How bright is 320 lumens?

320 lumens is roughly equivalent to a 30W incandescent bulb. This is accent lighting rather than task lighting — suitable for bedside lamps, decorative pendants, and mood lighting in living rooms or dining areas, but not bright enough for reading or detailed work.

Will it fit in a standard lamp holder?

Yes. The 60mm diameter and 117mm height are standard GLS dimensions. The B22 bayonet cap is the most common UK fitting and will work in any fixture designed for a standard incandescent or CFL bulb with a B22 base.
