Description
This is a slim tubular lamp in clear glass, with a straight filament held down the centre and a small screw cap at the base. The glass is left plain rather than frosted, so the filament reads as a bright line rather than a soft glow, and the light it gives is a warm white at 2700K. It draws 4W and puts out 470 lumens, spread all round rather than thrown forward, which suits fittings that show the lamp openly. We reach for it when a fitting needs something taller and quieter than a candle bulb.
It suits fittings where the lamp is on show: multi-arm chandeliers, wall lights with a clear or fabric shade, bedside lamps and small pendants over a side table. The all-round output means it works pointing up or down without a dark side. It is dimmable, though it needs a dimmer made for LED loads to run smoothly; a dimmer is not supplied with the lamp. If you are filling several holders in one fitting, we would keep the whole set to the same warm white so the arms match.
The body is glass throughout, clear and uncoated, with the filament visible end to end. Keep it clean by switching off at the wall, letting the glass cool, then dusting with a dry lint-free cloth; sprays and damp cloths do the filament no favours and can leave marks that show up once it is lit. It carries a three year warranty. We stock it as our plain warm-white option for small-cap fittings, and it pairs happily with clear glass shades, brass arms and dark metal frames where a covered lamp would look wrong.

Frequently Asked
What size is it?
The glass tube measures 45mm across and 110mm tall overall, including the cap, so check the internal height of any small shade before ordering.
Will it work with my existing dimmer?
Only if that dimmer is rated for LED loads. Older dimmers built for filament lamps can cause flicker or buzz at low settings, and a 4W lamp may sit below their minimum load.
How bright is it compared with an old filament bulb?
At 470 lumens it sits close to a 40W traditional lamp, and the 2700K warm white keeps the same yellow-toned light.
Does the clear glass cause glare?
The filament is visible, which is the point of a lamp like this, but it is a low-wattage line source rather than a broad glowing surface. In an open fitting at eye level, a shade or a higher mounting position helps.
How long should it last?
It is rated at 15,000 hours of use, and it carries a three year warranty.
Can I use it outdoors or in a bathroom?
No. Keep it to dry interior rooms and enclosed fittings indoors, away from damp and splashes.
