B22 LED Candle Bulb 4.9W 470lm - Daylight 6500K - Eveready

This is a candle bulb on a B22 bayonet cap, the push-and-twist fitting found on the majority of older British light fittings. It draws 4.9W and gives 470 lumens, and the Eveready retail pack rates that as the equal of a 40W conventional candle bulb. The light is daylight white at 6,500 Kelvin, the coolest and crispest of the usual white options. The envelope is opal white rather than clear, so the LEDs inside are diffused into an even glow instead of readable bright points.

Candle bulbs are made for fittings where the lamp itself is on show: chandeliers, wall lights, multi-arm ceiling fittings and small table lamps with clip-on shades. At 6,500K the light reads blue-white and neutral rather than cosy, which suits a kitchen, a home office, a utility room or a hobby bench, and it keeps whites looking white when you are reading paperwork or matching fabric. In a bedroom or a sitting room most people reach for 2,700K or 3,000K instead. The beam spreads to 280 degrees, close to all-round, so it lights an upward-facing shade as readily as a downward one.

This bulb is not dimmable, so put it on a plain switch; on a dimmer circuit expect flicker or buzz. It is rated IP20, meaning no protection against moisture, and carries energy class F. The pack prints a 10-year lamp life at 10,000 hours and more than 10,000 on and off switching cycles, which matters on a hall or landing light that gets flicked constantly. Supply is 220-240V. One box holds a single bulb and the minimum order is five. We also list the same 4.9W 470lm candle on the smaller B15 bayonet cap in warm white 3000K and cool white 4000K.

Will this fit my existing bayonet light fitting?

It takes a B22 bayonet cap, the larger of the two British bayonet sizes, with two pins that push in and twist a quarter turn. Check your old bulb is not the smaller B15 cap, which will not seat in a B22 holder.

How bright is 4.9W compared with an old filament candle?

The pack rates it as a 40W conventional replacement. The figure that matters is the 470 lumens, since wattage now only tells you what it costs to run rather than how much light you get.

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

It is a crisp blue-white with no yellow in it, the coolest of the common white options. It keeps colours honest for working, reading and task areas, and most people find it too stark for relaxing rooms.

Can I put it on a dimmer switch?

No. The specification lists it as non-dimmable, so it should go on a standard on and off switch. On a dimmer circuit you are likely to get flicker, buzzing or a shortened life.

How many bulbs do I actually receive?

Each box contains one bulb. The minimum order on this listing is five boxes, sold in multiples of five, so the smallest purchase is five single bulbs.
