4W Dimmable LED Tubular Filament Bulb E14 - Clear Glass 3000K

This 4W LED tubular filament bulb uses an E14 small Edison screw base and houses four vertical LED filaments inside a clear glass tubular envelope measuring 105mm tall by 27mm diameter. The bulb outputs 400 lumens at 3000K warm white and is compatible with most standard household dimmers, allowing brightness adjustment from full output down to around 10% depending on the dimmer model used.

Designed for decorative fixtures where the bulb remains visible, the tubular shape suits exposed pendant fittings, wall lights with open glass shades, and table lamps where the bulb acts as part of the aesthetic rather than being concealed. The vertical filament arrangement creates a symmetrical glow when lit, avoiding the asymmetry of some single-filament LED bulbs. The clear glass means no light is lost to frosting or coating, delivering the full 400lm through the tube.

The 27mm diameter fits standard E14 candelabra-style fittings commonly used in European and UK decorative lighting, including chandeliers, wall sconces and smaller pendant lights. At 4W draw the bulb generates minimal heat compared to equivalent 40W incandescent tubular bulbs, making it safer for enclosed fixtures and reducing cooling requirements. The LED technology delivers approximately 15,000-25,000 hours of rated life depending on usage patterns, significantly longer than halogen or incandescent alternatives.

The brass-finish E14 base provides a warm metallic accent when the bulb is installed in fixtures where the base remains visible, such as downward-facing or horizontal sockets. The dimmable function works best with leading-edge and trailing-edge LED-compatible dimmers — compatibility with older resistive dimmers varies by manufacturer and may produce flicker or limited dimming range.

Is this bulb dimmable with all dimmer switches?

The bulb is rated as dimmable and works with most LED-compatible leading-edge and trailing-edge dimmers. Older resistive dimmers designed for incandescent bulbs may cause flicker or limited dimming range. If dimming performance is critical, confirm your dimmer is LED-rated before purchase.

What is the light output equivalent to in incandescent watts?

At 400 lumens and 3000K, this 4W LED bulb produces similar light output to a traditional 40W incandescent tubular bulb, but uses approximately 90% less energy.

What fixtures does the E14 base fit?

E14 is the small Edison screw base commonly used in European and UK decorative fittings including chandeliers, wall sconces, and smaller pendant lights. It is smaller than the standard E27 Edison screw found in most UK table lamps and ceiling pendants.

Can this bulb be used in enclosed fixtures?

Yes. The 4W power draw generates minimal heat, making it suitable for enclosed glass shades and lanterns where incandescent or halogen bulbs would overheat. Check the fixture's maximum wattage rating to confirm compatibility.
