Description
This is a 5W LED filament bulb with an E27 screw cap, built in the ST64 teardrop shape that gives it its name: broad at the shoulder, tapering down to the cap. The glass carries a gold tint, and slim filament strands run up through the centre so the bulb has something to look at when it is lit and when it is off. It puts out 550lm at 2200K, a deep amber warm white that sits well below the 2700K of a standard warm white lamp. The pack rates it as a replacement for a 40W incandescent.
Amber filament bulbs are meant to be seen, so the fittings that suit this one best leave the glass exposed: a pendant on a plain flex, an open cage shade, a wall bracket that points the lamp outwards, or a table lamp under an open-topped shade. The 320 degree beam angle means light leaves almost the whole surface rather than firing one way, so a single bulb fills a hallway, a snug or the space over a kitchen island with a low, mellow glow. At 550lm this is a mood light rather than a working one, so pair it with something brighter over a worktop.
It is not dimmable, so wire it to an ordinary on and off switch. The energy label gives it class E, and the retail pack prints a 15,000 hour lifespan. It carries an IP20 rating, the usual figure for an indoor lamp in a dry, sheltered position. Each unit is a single bulb, and the minimum order is 12, sold in multiples of 12. Our wider LED bulb range also runs to GU10 spots and B15 candle and golf bulbs.

Frequently Asked
How do I know my fitting takes an E27 cap?
E27 is the larger of the two screw caps, often written as ES. If your old bulb twists in on a wide screw thread rather than pushing and turning on two pins, E27 is the one you want.
How bright is 5W in real terms?
It gives 550lm, and the pack rates that as a replacement for a 40W incandescent bulb. That is enough for a hallway, a bedside or a decorative pendant rather than task lighting.
Can I put it on a dimmer switch?
No. The specification states it is not dimmable, so it should be wired to a standard on and off switch rather than any dimming circuit or smart dimmer module.
What does 2200K light actually look like?
It is a deep amber, noticeably warmer and more golden than the 2700K warm white most people are used to, closer to the glow of an old carbon filament lamp.
Can I use it in an outdoor fitting?
It is rated IP20, which offers no protection against water, so keep it to indoor fittings in dry, sheltered positions rather than anywhere exposed to the weather.
