Description

Slim, upright and clear, this is a tubular lamp with a straight filament running the full length of the glass, so the light source itself is part of the look. The output is a crisp neutral white at 4000K, closer to daylight than to the warm yellow of an old filament bulb, and it gives around 470 lumens from a very low wattage. It dims too, provided the circuit already has a dimmer suited to LED loads.

We reach for this one where the bulb is on show: open pendants, cage fittings, clear glass shades and wall lights worn without a shade at all. The neutral white suits kitchens, home offices, workshops and utility rooms, anywhere you want light that reads clean rather than cosy. With an E27 screw cap it takes the most common size in British homes, and at 45mm across the tube sits comfortably inside narrow shades and cluster fittings without crowding its neighbours. On a dimmer it will pull right back for the evening, which makes it workable over a dining table as well as a worktop.

The body is plain clear glass, undecorated, with a filament array that stays visible whether the lamp is lit or cold. Keep that glass clean and it keeps its sparkle: switch off, let the tube cool fully in the fitting, then wipe it with a dry lint free cloth and keep sprays and damp away from the cap. It carries a three year warranty. A dimmer is not supplied with it. Where a room has several exposed lamps on view we would suggest matching them all to this one, since mixed colour temperatures are obvious the moment you look through clear glass.

Frequently Asked

Does it need a special dimmer?

Yes. It will dim, but only on a dimmer rated for LED loads; older dimmers built for filament bulbs may buzz, flicker or refuse to go low. No dimmer is supplied.

How bright is it, and how much does it draw?

It produces 470 lumens from 4W, so it suits general room lighting in multiples or a single point over a smaller space.

What size is the bulb?

The tube measures 45mm in diameter by 110mm in overall length, including the E27 cap.

Is 4000K warm or cool?

4000K is a neutral, slightly cool white. If you want the yellower glow of a traditional bulb for a living room or bedroom, choose a warmer colour temperature instead.

How long should it last?

It is rated at 15,000 hours of average life, which is several years of ordinary household use.

Can I use it in an outdoor fitting?

Fit it indoors. It is intended for enclosed or open fittings in dry rooms, not exposed garden or porch positions.
