Description

The Energizer ST64 is a 5W LED filament bulb with gold-tinted glass, an E27 screw base and exposed LED filament strips arranged to mimic the look of traditional carbon filament bulbs. Running at 5W on 230V mains, it produces 550 lumens at 2200K, a deep warm white tone closer to candlelight than standard warm white bulbs. The bulb is non-dimmable and serves as a direct replacement for 40W incandescent bulbs.

Designed for decorative fittings where the bulb is visible, the ST64 suits pendant lights, exposed-bulb chandeliers, wall sconces and table lamps where the filament contributes to the aesthetic. The 2200K colour temperature gives a warm amber glow that softens interiors and pairs well with industrial, vintage and hospitality settings. The 320° beam angle provides near-omnidirectional light distribution, useful when the bulb hangs unshrouded.

The gold tint on the glass filters the light slightly, adding warmth to the output and reducing the visual contrast between the glass and the filament when the bulb is off. At 64mm diameter and 145mm height, the ST64 shape is larger than a standard GLS bulb, so check the shade or fitting aperture before ordering. The bulb carries an Energy Rating of F under the updated 2021 EU energy label scale, which recalibrated ratings to reflect higher efficiency standards across LED products.

Frequently Asked

Is this bulb dimmable?

No. The Energizer ST64 is non-dimmable and should not be used with dimmer switches, as this can cause flickering or damage to the bulb.

What colour is the light output?

The bulb produces 2200K warm white light, which is a deep amber tone closer to candlelight than standard 2700K warm white. The gold-tinted glass adds further warmth to the output.

Will it fit my existing E27 light fitting?

The bulb uses a standard E27 Edison screw base, so it fits any E27 lampholder. However, the ST64 shape is larger than a standard GLS bulb at 64mm diameter and 145mm height, so check the fitting or shade aperture to ensure the bulb will sit correctly.

What is the lifespan?

Energizer rates this LED bulb at 15,000 hours of use based on typical operating conditions. At 3 hours per day, this equates to approximately 13-14 years before replacement is needed.
