E14 (SES) LED Filament Golf Bulb 4W 470lm - Warm White 2700K

This is an LED golf bulb on an E14 small Edison screw cap, built the filament way: four slim LED strips run vertically inside clear glass rather than hiding behind a frosted dome. It draws 4W and gives 470 lumens, which the pack puts at the equal of a conventional 40W bulb. The light is warm white at 2700K, the yellow-leaning tone people associate with old incandescent lamps, and it spreads across a 280 degree beam, so it throws light down, sideways and a good way back up past the cap.

Golf bulbs suit fittings where the lamp is part of what you look at: small chandeliers, wall lights with clip-on shades, bedside lamps and pendant clusters with clear or open shades. With clear glass the filaments are on show, which is the point in a bare-bulb pendant and worth thinking about in a reading lamp at eye level, where a shade or a higher fitting keeps the glare off. Check the old bulb before ordering: E14 is the smaller of the two screw caps at 14mm across the thread, and the larger E27 will not fit the same holder.

There is no dimming here: the specification and the pack both say non-dimmable, so put it on a plain on/off switch rather than a trailing-edge dimmer. The pack states a 10 year life at 10,000 hours and more than 8,000 switching cycles, which is the figure that counts on a hallway or landing light flicked on and off all day. It runs on 220 to 240V mains, carries an energy rating of E and is rated IP20, so keep it to dry indoor positions. Each box holds one bulb and the minimum order is five, sold in multiples of five. We stock other Eveready filament bulbs too, including the same 4W 470lm golf on a B15 (SBC) cap and a filament candle at the same output.

Which light fittings take an E14 cap?

E14 is the small Edison screw, 14mm across the thread, used by most small chandeliers, wall lights and bedside lamps. Unscrew the old bulb and compare it before ordering, because the larger E27 will not fit.

Is 4W really as bright as a 40W bulb?

It gives 470 lumens, and the pack rates that as the equal of a conventional 40W lamp. Lumens are the figure to compare when replacing older bulbs, rather than watts.

Can I put this on a dimmer switch?

No. Both the specification and the pack list it as non-dimmable, so it needs a standard on/off switch. On a dimmer it may flicker, buzz or fail early.

What does 2700K warm white actually look like?

2700K is the soft, yellow-leaning white of an old incandescent lamp. It flatters wood, warm paint colours and skin tones, and suits sitting rooms and bedrooms in the evening.

How well does it cope with being switched on and off often?

The pack prints a 10 year life at 10,000 hours and more than 8,000 switching cycles, so it is built for a switch used many times a day.

Will the filaments show through a clear shade?

Yes. The glass is clear and the four vertical filaments are fully on view, which suits open pendants and clear glass shades where the bulb is meant to be seen.
