Description

A slim clear glass tube with a Z-folded filament running its length, this is a decorative lamp meant to be looked at rather than hidden. The glass is left clear so the filament stays visible and reads as a bright line of warm light, and the 2700K colour sits comfortably with brass, wood and painted plaster. It draws 4W and takes the standard larger screw cap, E27. Dimming is possible with a suitable dimmer, which lets you bring the filament down to a low glow in the evening.

We reach for lamps like this where the fitting leaves the bulb on show: bare flex pendants over a kitchen island, an open cage, or a wall light with a shallow shade. At 185mm the tube is tall enough to fill a generous pendant without looking lost, while the narrow body keeps it neat inside a small opening. It suits anyone who likes the look of an old filament lamp but wants the modest running cost of LED. Several hung at staggered drops over a dining table make an easy, informal arrangement.

Construction is straightforward: clear glass over the filament assembly, with the screw cap at the base. Let it cool, then wipe the glass with a dry lint-free cloth; clear tubes show fingerprints and dust sooner than frosted ones, so an occasional wipe keeps the light crisp. It carries a three year warranty. It is intended for indoor fittings on a household supply, and no dimmer comes with it. Where the flex and lamp are both on display, we would choose the clear glass every time, and keep the shade shallow so the tube is not cut off halfway.

Frequently Asked

How much light does it give out?

It produces 300 lumens of warm white light at 2700K, which is a gentle, ambient level rather than a task brightness. It works best in decorative fittings, or in multiples where you want several points of light.

What are the dimensions?

The tube is 185mm tall and 30mm in diameter, so it stays slender inside a shade or cage while still filling a taller pendant.

Will it work with my existing dimmer?

It is dimmable, but it needs a dimmer suited to LED loads. Older resistive dimmers made for filament lamps can flicker or buzz with a 4W load, so check the dimmer is rated for LED and that its minimum load is low enough.

Which fittings take this cap?

It has an E27 cap, the larger of the two screw sizes, so it goes into any standard E27 lampholder.

How long should it last?

It has an average life of 15,000 hours, and it carries a three year warranty.

Does the clear glass cause glare?

The filament is visible and bright to look at directly, which is part of the appeal. In a seating area, dim it slightly or hang it above eye level so the filament reads as a warm line rather than a hotspot.
