Description

The Energizer ST64 is a 5W LED filament bulb with gold-tinted glass and an exposed LED filament arrangement designed to replicate the look of Edison-era carbon filament bulbs. The B22 bayonet cap fits standard UK ceiling roses and table lamp holders, and the 64mm diameter ST64 teardrop shape sits comfortably in open pendant fittings, chandeliers and decorative wall lights where the bulb is visible.

Operating at 5W and producing 470 lumens at 2700K, the bulb provides ambient warm white light suited to living rooms, dining areas and bedrooms where soft background illumination is needed rather than task lighting. The gold-tinted glass filters the LED output to give a warmer, more amber tone than clear glass equivalents, and the exposed filament creates a focal point when the bulb is viewed directly. The 320-degree beam angle distributes light broadly around the bulb rather than in a focused cone.

The bulb is non-dimmable and draws 5W on 230V mains, which replaces a traditional 30-40W incandescent bulb in light output while using approximately one-sixth of the power. The ST64 shape measures 64mm in diameter and 145mm in total height including the bayonet cap, so it needs adequate clearance in shallow shades or enclosed fittings. The energy rating of F reflects the decorative filament design rather than maximum efficiency — filament-style LEDs trade some efficiency for the visual appeal of the exposed LED strips.

Frequently Asked

Is this bulb dimmable?

No. The bulb is rated as non-dimmable and should not be paired with dimmer switches. Attempting to dim it may cause flickering, buzzing or premature failure.

What base type does it use?

This bulb uses a B22 bayonet cap, which is the standard UK fitting. It pushes and twists into the socket rather than screwing in like an E27 Edison screw base.

How does the gold tint affect the light output?

The gold-tinted glass filters the LED output to a warmer, more amber tone than clear glass bulbs. It reduces the perceived brightness slightly compared to a clear equivalent at the same lumen rating, but creates a softer, more atmospheric light suited to decorative fixtures.

Will it fit in a standard pendant shade?

The ST64 shape is 64mm in diameter and 145mm tall including the B22 cap. Most open pendant fittings accommodate this size comfortably, but enclosed or shallow shades may be too tight. Check the internal clearance of your fitting before purchasing.
