E27 (ES) LED Candle Bulb 4.9W 470lm Non-Dimmable - Daylight 6500K

A candle shaped LED bulb on an E27 screw cap, drawing 4.9W and putting out 470 lumens. The retail pack rates it as the equal of a 40W conventional candle bulb, so it is a direct swap for the older filament candles still sitting in many fittings. The light is 6,500K, the coolest of the standard white tones: a crisp blue white daylight rather than the yellow of a traditional bulb. The body is opal white with a smooth tapered tip, so the diodes behind it do not read as bright points through the surface.

E27 is the wider of the two screw caps, so check the old bulb: if the thread is noticeably fatter than a pencil it is E27 rather than the narrower E14. Candle bulbs of this shape suit multi arm ceiling fittings, wall lights and table lamps where part of the bulb is on show. A 6,500K daylight tone is a working light rather than a restful one, which makes it a sensible pick for a home office, a utility room or a craft table where you need to judge colours honestly. The 280 degree beam throws light almost all the way round, so open shades are fine.

There is no dimming, so keep it on a plain on/off switch; a non dimmable LED on a dimmer circuit can flicker or buzz. The pack prints a life of 10 years or 10,000 hours and more than 10,000 switching cycles, which suits a hall or landing light that gets flicked on and off all day. It runs on 220 to 240V mains, carries an energy rating of F and is rated IP20 for dry indoor use. Each unit is a single boxed bulb, and our minimum order is 5, sold in multiples of 5. We stock the same 4.9W 470lm candle on a B15 (SBC) cap in warm white, cool white and daylight.

How do I know my fitting takes an E27 cap?

Take the old bulb out and look at the base. E27 is a screw thread roughly 27mm across, the larger of the two common screw caps; if the thread looks slim and closer to 14mm, your fitting is E14 and this bulb will not screw in.

What does 6,500K daylight look like in the room?

It is a cool blue white, the brightest looking of the standard white tones and much whiter than an old filament bulb. It shows colours and detail clearly, which is useful for reading, sewing or work surfaces, but most people find it too cold for a sitting room.

Can I put it on a dimmer switch?

No. The specification lists this bulb as non dimmable, so it needs a plain on/off switch. Fitted to a dimmer circuit a non dimmable LED can flicker, hum or fail early, whatever position the dial is set to.

Is 470 lumens enough to replace my old bulb?

The pack rates the 470 lumen output as equal to a 40W conventional candle bulb, so it suits fittings that took 40W candles. In a multi arm ceiling light with several bulbs working together that is plenty for general lighting.

Can I use it outdoors or in a damp space?

No. It is rated IP20, which means no protection against water at all, so it is for dry indoor fittings only. Anywhere exposed to weather or splashing needs a lamp and fitting with a higher IP rating.

How long should one bulb last?

The pack prints a life of 10 years or 10,000 hours and more than 10,000 on and off cycles, so frequent switching in a hallway, stairwell or landing should not shorten it noticeably.
