E14 Capsule 4W LED Bulb 520lm - Cool White

This E14 capsule LED bulb is a small bi-pin lamp built for the fittings that once took a low-wattage halogen or older capsule bulb. It draws just 4W yet produces 520 lumens, which is enough to stand in for an old 42W bulb while using a fraction of the energy. The colour temperature is 4000K, a cool white tone that reads clean and neutral rather than yellow, and the 320 degree beam spreads light almost all the way around the lamp rather than firing it in one direction. American buyers searching for a candelabra-base capsule will recognise the format, though the cap here is the European E14 Small Edison Screw (SES) rather than the US E12.

The wide 320 degree spread and modest 520 lumen output suit it to small enclosed fittings and decorative fixtures where a compact lamp is needed and the light is shared across the room rather than aimed. Think wall lights, small pendants, lantern shades and multi-lamp fittings where several bulbs work together, as well as cabinet and display fittings that call for a discreet capsule. It is rated IP20, so keep it to dry indoor locations and clear of bathrooms, porches and any damp or outdoor settings. With an efficiency of 130 lm/W it runs cool and economically across long hours.

The bulb measures Ø16 by 54mm and weighs only 14g, so it fits neatly into compact shades and recessed sockets. It runs on 220 to 240V AC mains through the E14 SES cap and is non-dimmable, so pair it with a standard non-dimming switch. Colour rendering is Ra 80, giving honest enough colour for everyday rooms, and the rated lifespan is 20,000 hours. The finish is a plain white capsule body. Our range covers several caps and shapes, so matching lamps for other fittings are easy to find alongside it.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It uses an E14 cap, also called Small Edison Screw or SES, which is the smaller of the two common screw fittings. Check that your fitting takes E14 rather than the larger E27 (ES) before ordering. It will not fit a bayonet or GU10 holder.

What old bulb wattage does it replace?

The LED itself draws only 4W but produces 520 lumens, enough to replace an old 42W bulb. The 4W figure is the actual power it uses, not the equivalent, so you get the brightness of the older lamp at a fraction of the running cost.

Is this bulb dimmable?

No, this is a non-dimmable bulb, so it should be used on a standard on/off switch rather than a dimmer circuit. Fitting a non-dimmable LED to a dimmer can cause flicker or buzzing and may shorten its life.

What does cool white look like in a room?

At 4000K the light is a cool white, a clean and neutral tone that sits between warm yellow and bright daylight. It suits kitchens, work areas and display fittings where a crisp, modern light is preferred over a cosy glow. Colour rendering is Ra 80 for honest everyday colour.
